Claims (2)

1. Ausgleichsrotationspumpe mit einer eine Pumpkammer (15) bildenden Gehäuseanordnung (11), einem in der Pumpkammer drehbar angeordneten Pumpelement (17), das zwei sich vergrößernde Fluidkammern (55) und zwei sich verkleinernde Fluidkammern (57) bildet, wobei die Gehäuseanordnung einen mit den beiden sich vergrößernden Fluidkammern in Verbindung stehenden Fluideinlaß (49) und einen mit den beiden sich verkleinernden Fluidkammern in Verbindung stehenden Fluidauslaß (63) bildet, wobei das Pumpelement einen sich zusammen mit einer Antriebswelle (31) drehenden Rotor (25) aufweist, der eine Mehrzahl von Schlitzen (27) bildet, von denen jeder einen radial bewegbaren Rollenschieber (29) aufnimmt, wobei die Pumpkammer von einer durchgehenden gekrümmten Wandfläche (21) begrenzt ist, die zwei Einlaßbogenflächen von in der Drehrichtung des Rotors fortschreitend zunehmendem Radius und zwei Auslaßbogenflächen (65) von fortschreitend abnehmendem Radius aufweist, wobei jede der Auslaßbogenflächen mit einer Nockenfläche für große Verdrängung versehen ist; und wobei jeder der Schlitze eine Antriebsfläche (73), die sich gegen den benachbarten Rollenschieber anlegt und diesen antreibt, wenn das Pumpelement in einem Pumpbetrieb arbeitet, sowie einen gegenüberliegende Fläche (75) aufweist, dadurch gekennzeichnet, daß jede der Antriebsflächen einen wesentlichen Flächenabschnitt (77) aufweist, der mit Bezug auf eine Radillinie unter einem negativen Winkel ausgerichtet ist, wobei aufgrund des Eingriffes zwischen jedem der Rollenschieber und dem zugehörigen negativen Flächenabschnitt die auf den Rollenschieber einwirkende, radial nach außen wirkende Gesamtkraft verringert und dadurch ein Prellen des Rollenschiebers vermindert wird.
2. Ausgleichstrotationspumpe mit einem Pumpelement (17) nach Anspruch 1, gekennzeichnet durch einander diametral gegenüberliegende Einlässe (53) und einander diametral gegenüberliegende Auslässe (59) in einer Stirnplatte (39) der Kammer.
