Abstract

Verdrängerzellenpumpe zum Fördern eines Druckfluids aus einem Vorratsbehälter zu einem Verbräucher, mit einem Gehäuse, das von einer Antriebswelle durchsetzt ist und in dem ein Saugkanal, ein Auslaßkanal, ein Stromregelventil und ein Strombegrenzungsventil angeordnet sind, mit einem Deckel, in dem eine gehäuseseitige Steuerplatte und eine deckelseitige Stirnplatte vorgesehen sind sowie ein Rotorsatz. Gehäuse (2) und Stirnplatte (5) sind mit Saugnieren versehen, die derart ausgestaltet sind, dass ein Abheben der Schieber vom Kurvenring auch bei geringen Drehzahlen des Rotors verhindert wird.

Figure 00000001
Displacement cell pump for conveying a pressure fluid from a storage container to a consumer, with a housing which is penetrated by a drive shaft and in which a suction channel, an outlet channel, a flow control valve and a flow limiting valve are arranged, with a cover in which a housing-side control plate and a cover-side end plate are provided as well as a rotor set. Housing (2) and end plate (5) are provided with suction kidneys, which are designed in such a way that the slide is prevented from lifting off the cam ring even at low rotor speeds.
