Description

Spritzgerät Bei Spritzgeräten, die mit einer vom Hauptkolben unter Druck gesetzten Hilfsflüssigkeit und einem von dieser bewegten Hilfskolben arbeiten, ist die Rückführfeder, die den Hilfskolben nach Beendigung des Druckhubes in die Ausgangslage zurückschiebt, in der Spritzflüssigkeit untergebracht, wo sie von den schleifenden Bestandteilen sehr angegriffen wird.Sprayer For sprayers that have one of the main ram below Pressurized auxiliary fluid and an auxiliary piston moved by this work, is the return spring that moves the auxiliary piston into the Moves back to the starting position, housed in the spray liquid, where they are from the abrasive components is very attacked.

Der größtmögliche Durchmesser dieser Rückführfeder ist dabei nicht größer als der Durchmesser des Hilfskolbens. Bei besonders hohen Hubzahlen hat sich ergeben, daß auch bei voller Ausnutzung der gegebenen Grenzen die Rückführfeder zu schwach ist bzw. sehr bald bricht.The largest possible diameter of this return spring is not here larger than the diameter of the auxiliary piston. With particularly high stroke rates show that even with full utilization of the given limits, the return spring is too weak or breaks very soon.

Zur Beseitigung dieser Mängel ist gemäß der Erfindung die Rückführfeder des Hilfskolbens in einem die Kolbenführung umgebenden, mit der Hilfsflüssigkeit in Verbindung stehenden Ringraum angeordnet und der Hilfskolben an seinem der Hilfsflüssigkeit zugekehrten Ende mit einem der Rückführfeder .als Auflage dienenden Bund versehen. Das Auflagebund kann mit Aussparungen versehen sein, die den Zutritt :der Hilfsflüssigkeit zum Ringraum ermöglichen.To remedy these shortcomings, the return spring is according to the invention of the auxiliary piston in a surrounding the piston guide, with the auxiliary liquid arranged in communicating annular space and the auxiliary piston at its the auxiliary liquid The end facing the return spring is provided with a covenant serving as a support. The support collar can be provided with recesses that allow access: the auxiliary liquid to allow annulus.

In der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung schematisch dargestellt.In the drawing is an embodiment of the subject matter of Invention shown schematically.

Abb. z zeigt den Hilfskolben mit den benachbarten Teilen des Spritzgeräts im Schnitt, Abb.2 eine Stirnansicht des Hilfskolbens allein.Fig. Z shows the auxiliary piston with the adjacent parts of the sprayer in section, Fig. 2 is an end view of the auxiliary piston alone.

In einem Zylinder 519 ist ein Hilfskolben 522 geführt, der am hilfsflüssigkeitsseitigen Ende einen Bund 522R aufweist. In diesem sind Aussparungen 5221' (Abb. 2) vorgesehen. Die Rückführfeder 523 liegt gegen diesen Bund 522a an und ist in einem die Kolbenführung 519a ringförmig umgebenden Raum 519v untergebracht. Dieser Raum steht durch die Ausschnitte 522b bei angelüftetem Hilfskolben mit der Hilfsflüssigkeit in Verbindung. Die Feder 523 liegt alsfl in der schmierenden Hilfsflüssigkeit statt im Spritzgut, was für ihre Lebensdauer vorteilhaft ist.An auxiliary piston 522 is guided in a cylinder 519 and has a collar 522R at the end on the auxiliary fluid side. In this recesses 5221 ' (Fig. 2) are provided. The return spring 523 rests against this collar 522a and is accommodated in a space 519v that surrounds the piston guide 519a in an annular manner. This space is connected to the auxiliary liquid through the cutouts 522b when the auxiliary piston is lifted. The spring 523 is located in the lubricating auxiliary fluid instead of in the spray material, which is advantageous for its service life.

Der Hilfskolben fördert das durch dieExnlaßöffnlmg 524 dem Zylinderraum zufließende Spritzgut über ein Kugelrückschlagventil 27 der Spritzdüse zu. Der Ventilkörper ist entsprechend mit 26, der .darin vorgesehene Rücklaufkanal mit 37 und die Zwischenplatte zwischen Haupt- und Hilfszylinder mit 20 gekennzeichnet.The auxiliary piston conveys this through the outlet opening 524 to the cylinder space inflowing spray material via a ball check valve 27 to the spray nozzle. The valve body is correspondingly with 26, the return channel provided therein with 37 and the intermediate plate marked with 20 between the main and auxiliary cylinders.
