Description

Die Erfindung bezieht sich auf eine Spritzpistole zum Versprühen von Farben und ähnlichen viskosen Medien, die pneumatisch antreibbar ist, bestehend aus einem Pistolengehäuse zur Aufnahme der den Antrieb, die Vermischung und/oder die Dosierung bewirkenden Bauteile der Spritzpistole, einem von dem Pistolengehäuse abstehenden Griffstück und einem an dem Pistolengehäuse abnehmbar befestigten Vorratsbehälter zur Aufnahme des zu verarbeitenden Mediums, wobei das Gehäuse der Spritzpistole einen Luftführungskanal aufweist, durch den die die Zerstäubung bewirkende Druckluft einer Zerstäuberdüse zuströmt, sowie auf eine Vorrichtung zur Führung und/oder Verteilung von Gasen, insbesondere von Druckluft, mit einem Gehäuse, in dem ein Luftführungskanal vorgesehen ist.The invention relates to a spray gun for spraying paints and similar viscous media, which is pneumatically driven, consisting of a gun housing for receiving the drive, the mixing and / or the dosage-causing components of the spray gun, a projecting from the gun body handle and a reservoir on the gun housing removably mounted for receiving the medium to be processed, wherein the housing of the spray gun has an air duct through which the sputtering effecting compressed air flows to a spray nozzle, and to a device for guiding and / or distribution of gases, in particular compressed air , with a housing in which an air duct is provided.

Bei den bekannten Spritzpistolen dieser Art sind die Flächen der einzelnen Bauteile, die mit der zur Zerstäubung vorgesehenen Druckluft in Berührung kommen, damit der Reibungswiderstand gering gehalten wird, glatt ausgebildet. Diese Ausgestaltungen haben sich in der Praxis zwar bewährt, eine Steigerung der Zerstäuberleistung ist hierbei aber nur durch eine Erhöhung des Förderdruckes möglich. Dies erfordert einen mitunter erheblichen Bauaufwand und ständig eine erhöhte Leistungsaufnahme, so dass dadurch der Wirkungsgrad und die Wirtschaftlichkeit einer Spritzpistole ungünstig beeinflusst werden.In the known spray guns of this type, the surfaces of the individual components which come into contact with the compressed air intended for atomization, so that the frictional resistance is kept low, smooth. Although these embodiments have proven themselves in practice, it is only possible to increase the atomizer output by increasing the delivery pressure. This requires a sometimes significant construction costs and constantly increased power consumption, so that thereby the efficiency and economy of a spray gun are adversely affected.

Aufgabe der Erfindung ist es daher, eine Spritzpistole bzw. eine Vorrichtung zur Führung und/oder Verteilung von Gasen in der Weise auszubilden, dass allein mit baulichen Maßnahmen eine Erhöhung der Luftgeschwindigkeit und damit eine Steigerung der Fördermenge des zu verteilenden bzw. weiterzuleitenden Mediums zu erzielen ist. Der dazu erforderliche Bauaufwand soll gering gehalten werden, auch soll die Funktionalität im vollen Umfang gewährleistet sein, dennoch soll eine erheblich höhere Menge des Mediums mit gleichem Energieaufwand aber höherer Geschwindigkeit transportiert werden können.The object of the invention is therefore to form a spray gun or a device for guiding and / or distribution of gases in such a way that alone with structural measures to achieve an increase in the air velocity and thus an increase in the delivery of the medium to be distributed or forwarded is. The required construction work should be kept low, also the functionality should be fully guaranteed, yet a significantly higher amount of the medium with the same energy consumption but higher speed can be transported.

Gemäß der Erfindung wird dies bei einer Spritzpistole der vorgenannten Art dadurch erreicht, dass die von der strömenden Druckluft beaufschlagten bzw. benetzten Flächen des Luftführungskanals und/oder der Zerstäuberdüse und/oder einer Luftkappe ganz oder teilweise mit einer strukturierten Oberfläche versehen sind, indem in diese aneinander anschließend oder mit seitlichem Abstand zueinander angeordnet Vertiefungen und/oder Erhöhungen eingearbeitet sind.According to the invention this is achieved in a spray gun of the aforementioned type, characterized in that the acted upon by the flowing compressed air or wetted surfaces of the air duct and / or the atomizer nozzle and / or an air cap are wholly or partially provided with a structured surface by in this successively or laterally spaced depressions and / or elevations are incorporated.

Die Vorrichtung zur Führung und/oder zur Verteilung von Gasen ist dadurch gekennzeichnet, dass die von der strömenden Druckluft beaufschlagten bzw. benetzten Flächen des Gehäuses ganz oder teilweise mit einer strukturierten Oberfläche versehen sind, indem in diese aneinander anschließend oder mit seitlichem Abstand zueinander angeordnet Vertiefungen und/oder Erhöhungen eingearbeitet sind.The device for guiding and / or distributing gases is characterized in that the areas acted upon by the flowing compressed air or wetted surfaces of the housing are wholly or partially provided with a structured surface by successively in this or laterally spaced recesses and / or elevations are incorporated.

Die projezierten Flächen der Vertiefungen und/oder Erhöhungen können jeweils kreisförmig, rechteckig, oval, elliptisch, linsenförmig oder polygon ausgebildet sein.The projected areas of the depressions and / or elevations may each be circular, rectangular, oval, elliptical, lenticular or polygonal.

Auf den von strömender Druckluft beaufschlagten Flächen können regelmäßig ausgebildete Vertiefungen und Erhöhungen, vorzugsweise gleichmäßig verteilt, angeordnet sein. Es ist aber auch möglich, auf den von strömender Druckluft beaufschlagten Flächen unregelmäßig ausgebildete Erhöhungen und Vertiefungen ungleichmäßig verteilt anzuordnen.On the acted upon by flowing compressed air surfaces regularly formed depressions and elevations, preferably evenly distributed, can be arranged. But it is also possible to disperse unevenly distributed on the surfaces acted upon by flowing compressed air irregularly formed elevations and depressions.

Die Vertiefungen und/oder Erhöhungen können auch als in Strömungsrichtung ausgerichtete, vorzugsweise sich überlappende Schuppen gestaltet sein.The depressions and / or elevations can also be designed as flow-aligned, preferably overlapping flakes.

Die Vertiefungen und/oder Erhöhungen sollten eine laterale Ausdehnung von 1 bis 10 mm und eine maximale Tiefe bzw. eine Höhe von etwa maximal 3 mm aufweisen.The depressions and / or elevations should have a lateral extent of 1 to 10 mm and a maximum depth or a height of about a maximum of 3 mm.

Werden die Flächen einer Spritzpistole bzw. einer Vorrichtung, die mit Druckluft unmittelbar in Berührung kommen, gemäß der Erfindung ausgebildet, so ist bei gleichem Energieaufwand wie bei herkömmlichen glatten Berührungsflächen eine erhebliche Erhöhung der Fördergeschwindigkeit gegeben, so dass die Fördermengen wesentlich gesteigert werden können, ohne dass es einen erhöhten Energieaufwand bedarf. Durch die vorgesehenen Vertiefungen und/oder Erhöhungen wird nämlich der Luftwiderstand an den Oberflächen der Bauteile verringert. Je nach Art und Anordnung der Vertiefungen und/oder Erhöhungen können Steigerungen der Fördermengen bis zum 30 % erzielt werden. Ohne großen Bauaufwand, vor allem aber ohne eine zusätzliche Leistungsaufnahme des Förderaggregates, wird auf diese Weise die Fördermenge eines zu verarbeitenden Mediums beachtlich gesteigert.If the surfaces of a spray gun or a device that come into direct contact with compressed air, formed according to the invention, so with the same energy consumption as in conventional smooth contact surfaces, a significant increase in the conveying speed is given, so that the flow rates can be significantly increased, without that it requires an increased energy expenditure. The provided depressions and / or elevations namely the air resistance is reduced at the surfaces of the components. Depending on the nature and arrangement of the depressions and / or elevations increases in flow rates up to 30% can be achieved. Without large construction costs, but especially without an additional power consumption of the delivery unit, the delivery rate of a medium to be processed is considerably increased in this way.

Die in Figur 1 dargestellte und mit 1 bezeichnete Spritzpistole dient zum Versprühen von Farben und ähnlichen viskosen Medien und besteht im Wesentlichen aus einem Pistolengehäuse 2 zur Aufnahme der zum Betrieb der Spritzpistole 1 erforderlichen Bauteile, einem von dem Pistolengehäuse 2 abstehenden Griffstück 3 sowie einem Vorratsbehälter 5 zur Aufnahme des zu verarbeitenden Mediums. Zum Auslösen eines Spritzvorganges ist ein verschwenkbar gelagerter Betätigungshebel 6 vorgesehen, bei dessen Verstellung mittels der über eine Druckluftleitung 7 zugeführten Druckluft das aus dem Vorratsbehälter 5 angesaugte Medium vermischt mit Luft aus einer Zerstäuberdüse 4 ausgestoßen wird.The spray gun shown in FIG. 1 and designated 1 is used for spraying paints and similar viscous media and consists essentially of a gun housing 2 for receiving the components required for operating the spray gun 1, a handle 3 projecting from the gun housing 2 and a reservoir 5 for receiving the medium to be processed. To initiate an injection process, a pivotally mounted actuating lever 6 is provided, in the adjustment by means of the compressed air via a compressed air line 7 compressed air sucked from the reservoir 5 medium mixed with air from a spray nozzle 4 is ejected.

Der Vorratsbehälter 5 ist bei dem gezeigten Ausführungsbeispiel in einem Ansatzstück 8 eingeschraubt, das fest mit dem Pistolengehäuse 2 verbunden und in das ein Kanal 9 eingearbeitet ist, der an den Vorratsbehälter 5 und an einen Ringraum 10 angeschlossen ist. Der Ringraum 10 ist durch eine Hülse 12 geschaffen, in die eine Düsennadel 13 eingesetzt ist. Entgegen der Kraft einer Druckfeder 14 ist die Düsennadel 11 mit Hilfe des Griffstückes 6 nach rechts verstellbar, so dass durch die der Spritzpistole 1 zugeführte Druckluft das zu verarbeitende Medium aus dem Vorratsbehälter 5 angesaugt und durch die Zerstäuberdüse 4, die mittels einer Düsenmutter 11 an dem Pistolengehäuse 2 und der Hülse 12 abgestützt ist, ausgestoßen wird.The reservoir 5 is screwed in the embodiment shown in an extension piece 8, which is firmly connected to the gun body 2 and in which a channel 9 is incorporated, which is connected to the reservoir 5 and an annular space 10. The annular space 10 is created by a sleeve 12 into which a nozzle needle 13 is inserted. Contrary to the force of a compression spring 14, the nozzle needle 11 by means of the handle 6 is adjustable to the right, so sucked by the spray gun 1 supplied compressed air to be processed medium from the reservoir 5 and through the atomizer 4, by means of a Nozzle nut 11 is supported on the gun housing 2 and the sleeve 12 is ejected.

Um die Luftgeschwindigkeit in dem Pistolengehäuse 2 sowie zwischen der Zerstäuberdüse 4 und einer dieser zugeordneten Luftkappe 15 zu erhöhen, sind bei der Spritzpistole 1 sämtliche von der strömenden Druckluft beaufschlagten bzw. benetzten Flächen eines in dem Pistolengehäuse 2 vorgesehenen Luftführungskanals 21, somit dessen Innenmantelfläche 22, sowie der Zerstäuberdüse 4 und der Luftkappe 15 - und auch die in dieser eingeformten Kanäle 16 - mit Vertiefungen 51 und/oder Erhöhungen 52, die unterschiedlich ausgebildet sein können, versehen. Auf diese Weise wird der Luftwiderstand verringert, so dass die Fördermengen, ohne dass eine erhöhte Leistungsaufnahme notwendig ist, wesentlich gesteigert werden.In order to increase the air velocity in the gun housing 2 as well as between the atomizer nozzle 4 and an air cap 15 associated therewith, in the spray gun 1, all areas of an air duct 21 provided in the gun housing 2, ie its inner jacket surface 22, are acted upon or wetted by the flowing compressed air. as well as the atomizer nozzle 4 and the air cap 15 - and also the channels 16 formed therein - with depressions 51 and / or elevations 52, which can be designed differently. In this way, the air resistance is reduced, so that the flow rates, without an increased power consumption is necessary to be substantially increased.

Auch bei den in den Figuren 4 und 5 dargestellten und mit 31 bzw. 41 bezeichneten Vorrichtungen zur Führung und/oder Verteilung von Gasen sind die von diesen beaufschlagten Flächen eines Gehäuses 32 bzw. 42 zu dem gleichen Zweck auf den Innenmantelflächen 33 bzw. 43 mit Vertiefungen 51 und/oder Erhöhrungen 52 ausgestattet. Die Vorrichtung 31 ist hierbei mit einem als Düse ausgebildeten Austrittsglied 34, die Vorrichtung 41 dagegen mit einem Einlassglied 44, so dass diese als Diffusor wirkt, ausgestattet.Also in the devices shown in Figures 4 and 5 and designated 31 and 41 for guiding and / or distribution of gases are acted upon by these surfaces of a housing 32 or 42 for the same purpose on the inner circumferential surfaces 33 and 43, respectively Wells 51 and / or ridges 52 equipped. In this case, the device 31 is equipped with an outlet member 34 designed as a nozzle, whereas the apparatus 41 is equipped with an inlet member 44, so that it acts as a diffuser.

In den Figuren 6a bis 13 ist in Abwicklungen im Einzelnen jeweils schematisch dargestellt, wie die Vertiefungen 51 und/oder die Erhöhungen 52 ausgebildet sein können.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 6a to 13, each of the developments in detail shows schematically how the recesses 51 and / or the elevations 52 can be formed.

Gemäß Figur 6a sind die in die Innenmantelfläche 22 eingearbeiteten Vertiefungen 51 in ihrer projezierten Fläche kreisförmig gestaltet und mit seitlichem Abstand zueinander regelmäßig angeordnet. In Figur 6b sind die Vertiefungen 51 dagegen seitlich versetzt an der Innenmantelfläche 22 angebracht. Nach Figur 6c grenzen die Vertiefungen 51 unmittelbar aneinander an, nach Figur 6d sind die im Durchmesser größer als bei den vorhergehenden Ausgestaltungen gewählten Vertiefungen 51 in Reihe angeordnet.According to FIG. 6 a, the indentations 51 incorporated in the inner lateral surface 22 are circular in their projected area and arranged regularly at a lateral distance from one another. In contrast, in FIG. 6b, the depressions 51 are attached laterally offset on the inner lateral surface 22. According to FIG. 6c, the recesses 51 adjoin one another directly, and according to FIG. 6d, the recesses 51, which are larger in diameter than in the previous embodiments, are arranged in series.

Die Figuren 7a und 7b zeigen Schnittdarstellungen des Pistolengehäuses 2, so dass die Vertiefungen 51 und die Erhöhungen 52 als solche erkennbar sind.Figures 7a and 7b show sectional views of the gun body 2, so that the recesses 51 and the elevations 52 are recognizable as such.

Gemäß Figur 8 können die Vertiefungen 51' oval bzw. elliptisch gestaltet sein, in ihrer projezierten Fläche sind die in Figur 9 dargestellten Vertiefungen 51" als Sechskant ausgebildet.According to FIG. 8, the depressions 51 'can be oval or elliptical; in their projected area, the depressions 51 "shown in FIG. 9 are formed as hexagon.

Nach Figur 10 sind in die Innenmantelfläche 22 in regelmäßigen Abständen zueinander kreisförmige Vertiefungen 51 sowie sechseckige Vertiefungen 51" eingearbeitet, nach Figur 11 dagegen kreisförmige Vertiefungen 51 sowie quadratische Vertiefungen 51'''. Figur 12 zeigt die Anordnung von kreisförmigen Vertiefungen 51 und mehreckigen Vertiefungen 51'v in der Innenmantelfläche 22.Referring to Fig. 10, circular depressions 51 and hexagonal depressions 51 "are incorporated in the inner circumferential surface 22 at regular intervals, whereas circular depressions 51 and square depressions 51 '" are shown in Fig. 11. Fig. 12 shows the arrangement of circular depressions 51 and polygonal depressions 51 ' v in the inner circumferential surface 22nd

Die Innenmantelfläche 22 des Luftkanals 21 der Spritzpistole 1 -wie auch die anderen von Druckluft beaufschlagten Flächen - kann aber auch, wie dies der Figur 13 zu entnehmen ist, mit Erhöhungen 52' - und/oder Vertiefungen - ausgestattet sein, die in Form von Schuppen gestaltet sind. Die Innenmantelfläche 22 ist somit gewissermaßen mit einer Haifischhaut überzogen, durch die der Strömungswiderstand der strömenden Druckkluft herabgesetzt wird.The inner lateral surface 22 of the air channel 21 of the spray gun 1 -as well as the other acted upon by compressed air surfaces can also, as can be seen in Figure 13, with elevations 52 '- and / or depressions - be equipped in the form of dandruff are designed. The inner lateral surface 22 is thus to a certain extent covered with a shark skin, by means of which the flow resistance of the flowing pressure gap is reduced.
