Description
DEUTSCHESGERMAN
Die Erfindung betrifft einen die als Klappenventile ausgebildeten Saug- und Druckventile enthaltenden zylindrischen Ventileinsatz für Pumpen, insbesondere für Zahnradpumpen und andere Pumpen mit rotierendem Verdränger, die bei Drehrichtungswechsel ihre Förderrichtung nicht umkehren dürfen. Er unterscheidet sich von den bekannten ähnlichen Ausführungen darin, daß die Klappe des Saugventils eine zylindrische Dichtfläche besitzt, die der Innenfläche der den Ventileinsatz aufnehmenden Bohrung des Pumpengehäuses entspricht, die den Sitz für die Klappe bildet.The invention relates to a suction and pressure valve containing the designed as flap valves cylindrical valve insert for pumps, especially for gear pumps and other pumps with rotating Displacers that are not allowed to reverse their conveying direction when the direction of rotation is changed. He differentiates differs from the known similar designs in that the flap of the suction valve is cylindrical Has a sealing surface that corresponds to the inner surface of the bore of the pump housing that receives the valve insert corresponds to that forms the seat for the flap.
Diese Bauart bringt gegenüber den bisher bekannten Konstruktionen, wo neben der Klappe des Druckventils auch für die Klappe des Saugventils eine Sitzfläche innerhalb des Ventileinsatzes vorhanden sein mußte, eine wesentliche Vereinfachung in Konstruktion und Herstellung sowie Raumersparnis. Während man derartige Ventileinsätze der bisher bekannten Konstruktionen wegen der schwierigen Bearbeitung des innerhalb des Ventileinsatzes liegenden Saugventilsitzes oft zweiteilig ausführen mußte, kann der Ventileinsatz nach der Erfindung einteilig ausgeführt werden. Eine besondere Bearbeitung der Saugventilsitzfläche entfällt überhaupt, da diese durch die Aufnahmebohrung im Pumpengehäuse bereits vorhanden ist.This design brings compared to the previously known constructions, where next to the flap of the pressure valve There is also a seat inside the valve insert for the flap of the suction valve had to be, a significant simplification in design and manufacture as well as space saving. While you have such valve inserts of the previously known constructions because of the difficult Machining of the suction valve seat located within the valve insert often had to be carried out in two parts, the valve insert according to the invention can be made in one piece. A special processing of the There is no suction valve seat surface at all, as this is already present due to the mounting hole in the pump housing is.
Die Zeichnung zeigt als Beispiel die Anwendung des neuen Ventileinsatzes bei einer Zahnradpumpe für gleichbleibende Förderrichtung bei wechselnder Drehrichtung, wozu zwei Einsätze erforderlich sind, α ist das Pumpengehäuse mit den Bohrungen h, die zur Aufnahme der Ventileinsätze c vorgesehen sind. Diese tragen in den Stirnwänden befestigte Bolzen f, auf denen die Klappe d des Saugventils bzw. die Klappe e des Druckventils drehbar gelagert sind. Die Klappen d, e werden durch Federn g auf ihre Sitze gedrückt. Der Sitz für das Druckventil e befindet sich am Ventileinsatz c, während der Sitz des Saugventils durch die Innenfläche der den Ventileinsatz c aufnehmenden Bohrung b im Pumpengehäuse a gebildet wird.The drawing shows as an example the application of the new valve insert in a gear pump for constant delivery direction with alternating direction of rotation, for which two inserts are required, α is the pump housing with the bores h, which are provided for receiving the valve inserts c . These carry bolts f fastened in the end walls, on which the flap d of the suction valve and the flap e of the pressure valve are rotatably mounted. The flaps d, e are pressed onto their seats by springs g. The seat for the pressure valve e is located on the valve insert c, while the seat of the suction valve is formed by the inner surface of the bore b in the pump housing a that accommodates the valve insert c.
Durch Drehung der Zahnräder h, i im Sinne der eingezeichneten Pfeile entsteht an der rechten Seite Ventileinsatz für PumpenBy rotating the gears h, i in the direction of the arrows shown, a valve insert for pumps is created on the right-hand side

Bei einem Drehrichtungswechsel schließt das rechte und öffnet das linke Saugventil d und schließt das linke und öffnet das rechte Druckventil e, so daß in jedem Fall bei ,S" Saugwirkung und bei D Druckwirkung herrscht.a suction action and a pressure action on the left, which causes the right suction valve d and the left pressure valve e to open and the conveyed medium to flow in the direction of the arrows shown. When the direction of rotation changes, the right suction valve closes and the left suction valve d opens and the left suction valve closes and the right pressure valve e opens, so that there is suction in every case with "S" and pressure effect with D.
