Description

Die Erfindung bezieht sich auf Flüssigkeitsverteiler, die insbesondere zum Aufspritzen von Anstrichfarben auf die Wagenkasten von Kraftfahrzeugen Verwendung finden und im wesentliehen aus einem Farbbehälter bestehen, der mit einem einen Teil des Apparats bildenden Räume, in welchem Luft zusammengepreßt wird, in Verbindung gebracht werden kann.The invention relates to liquid distributors, in particular for spraying paints onto the car bodies of motor vehicles Find use and essentially consist of a paint container that with a space forming part of the apparatus in which air is compressed can be associated.

Gemäß der Erfindung sollen diese Flüssigkeitsverteiler mit einer Vorrichtung versehen werden, welche ermöglicht, im Augenblicke des Schließens die Flüssigkeit zurückzuhalten, die sich zwischen der Verschlußvorrichtung und der Austrittsöffnung befindet. Zu diesem Zwecke wird in die Ausspritzleitung ein Schieber eingeschaltet, der mit einer öffnung versehen ist, um die Verbindung zwischen Behälter und Austrittsdüse herzustellen. Dieser Schieber bildet einen Kolben und erzeugt durch seine Verao Schiebung beim Verschließen der Verbindung einen Unterdruck in der Austrittsdüse, so daß ein Ansaugen der Farbe bewirkt wird, die etwa in der Düse zurückgeblieben ist, und das Auftreten von Flecken vermieden wird, die sich sonst durch die Düse beim Verschließen der Verbindung zwischen Behälter und Austrittsdüse bilden wurden.According to the invention, these liquid distributors are to be provided with a device which enables the liquid to be retained at the moment of closing is located between the closure device and the outlet opening. To this end If a slide is switched on in the injection line, which is provided with an opening, to establish the connection between the container and the outlet nozzle. This slide forms a piston and generated by its verao Shift when closing the connection a negative pressure in the outlet nozzle, so that a Sucking in the paint that is roughly left in the nozzle is caused and the occurrence Avoid stains that would otherwise pass through the nozzle when closing the connection between the container and the outlet nozzle.

Die Zeichnung stellt eine Ausführungsform des Erfindungsgegenstandes beispielsweise dar, und zwar zeigt Abb. 1 den Apparat in der Ruhestellung. Abb. 2 zeigt den Apparat in Arbeitsstellung, in welcher der Verteiler die Verbindung zwischen dem Behälter und der Austrittsdüse herstellt.The drawing shows an embodiment of the subject matter of the invention, for example, namely Fig. 1 shows the apparatus in the rest position. Fig. 2 shows the apparatus in working position, in which the manifold is the connection between the container and the outlet nozzle manufactures.

Der Apparat besitzt einen Behälter 1 von bestimmtem Rauminhalt, der beispielsweise der Farbmenge entspricht, die zum Bespritzen eines Wagens erforderlich ist. Dieser Behälter 1 steht in Verbindung mit einer Austrittsdüse 2, deren Ende pfeifenartig abgeschnitten ist und dazu dient, den Earbenstrahl auf die zu behandelnde Fläche zu richten. Ein Verteiler in Gestalt eines Schiebers 3, der unter der Einwirkung einer Gegenfeder 4 steht und durch einen Griff 5 gesteuert wird, welcher mittels einer Achse 6 an den Körper des Apparats angelenkt ist, ermöglicht die Herstellung der Verbindung des Behälters 1 mit der Düse 2 durch einen Kanal 3', der durch den Körper des Verteilers hindurchgebohrt ist. Der Schieber 3 verschiebt sich in dem Räume 4', der durch den Kanal 2' mit dem Düsenkanal 2 in Verbindung steht.The apparatus has a container 1 of a certain volume, which corresponds, for example, to the amount of paint required to spray a car. This container 1 is connected to an outlet nozzle 2, the end of which is cut off like a pipe and serves to direct the earbone jet onto the area to be treated. A distributor in the form of a slide 3, which is under the action of a counter spring 4 and controlled by a handle 5 articulated to the body of the apparatus by means of an axis 6, enables the connection of the container 1 to the nozzle 2 to be made a channel 3 'drilled through the body of the manifold. The slide 3 moves in the space 4 ', which is connected to the nozzle channel 2 through the channel 2'.

Der Farbbehälter 1 steht durch seinen mit einem Stutzen 7 versehenen Deckel mit einer Druckluft- oder Druckgasquelle in Verbindung, die ihren Druck auf die Farbe ausübt und sie durch die Düse 2 hindurch nach außen treibt. Bei der in der Zeichnung veranschaulichten Ausführungsform bringt man auf dem Stutzen 7 eine zweckmäßig aus zwei Körpern bestehende Kautschukbirne 8 an, die mit der Hand betätigt werden kann.The paint container 1 is through its provided with a nozzle 7 cover with a Compressed air or compressed gas source in connection, which exerts its pressure on the paint and it propels through the nozzle 2 to the outside. When illustrated in the drawing Embodiment brings one expediently consisting of two bodies on the connecting piece 7 Rubber bulb 8, which can be operated by hand.

Die Arbeitsweise des Apparats ist folgende: Nachdem man den Farbbehälter 1 gefüllt und den erforderlichen Druck mit der Birne 8 er- 6g zeugt hat, nimmt man den Apparat in die Hand und richtet die Düse 2 gegen die Fläche, die bespritzt werden soll. Man betätigt dann den Griff 5 derart, daß die Verbindung zwischen der Düse 2 und dem Behälter 1 hergestellt wird. Ist das Aufspritzen beendet, so läßt man den Griff 5 los und der Schieber 3 wird unter der Einwirkung seiner Feder 4 in die Verschlußstellung zurückgeführt. Bei dieser Verschiebung erzeugt der Schieber einen Unterdruck im Räume 4' und in dem Kanal 2', der mit der Austrittsdüse 2 in Verbindung steht. Es ergibt sich hieraus, daß zu derselben Zeit, wo der Schieber in die Verschlußstellung gebracht wird, in der Austrittsdüse ein Unterdruck erzeugt wird, so daß einige Farbtropfen, die etwa in der Düse verblieben sind und beim Austreten aus der Düse Flecken erzeugen könnten, in den Raum 4' hineingesaugt werden, der eine Saugöffnung mit Verschluß besitzen kann.The operation of the apparatus is as follows: After the paint container 1 has been filled and the required pressure has been generated with the bulb 8, the apparatus is taken in hand and the nozzle 2 is directed towards the surface to be sprayed. The handle 5 is then operated in such a way that the connection between the nozzle 2 and the container 1 is established. When the spraying has ended, the handle 5 is released and the slide 3 is returned to the closed position under the action of its spring 4. During this displacement, the slide generates a negative pressure in the space 4 'and in the channel 2', which is connected to the outlet nozzle 2. It follows from this that at the same time that the slide is brought into the closed position, a negative pressure is generated in the outlet nozzle, so that some paint drops that have remained in the nozzle and could create spots when exiting the nozzle are in the space 4 'are sucked in, which can have a suction opening with a closure.
