Abstract

Die vorliegenden Erfindung betrifft eine Steuerscheibe (2) insbesondere für Flügelzellenpumpen welche eine Saugöffnung (4) und eine Drucköffnung (3) aufweist. Um eine Entlüftung von Luft zu ermöglichen, welche über die Saugöffnung (4) mit angesaugt wurde, ist an der Drucköffnung (3) der Steuerscheibe (2) eine Entlüftungsvorrichtung vorgesehen, welche in Form einer nutförmigen Aussparung (6) in der Steuerscheibe (2) ausgebildet ist.

Figure 00000001
The invention relates to a control disk (2), in particular for vane pumps, which has a suction opening (4) and a pressure opening (3). In order to enable ventilation of air that was also sucked in via the suction opening (4), a ventilation device is provided on the pressure opening (3) of the control disc (2), which is in the form of a groove-shaped recess (6) in the control disc (2) is trained.
