Claims (22)
dadurch gekennzeichnet,
daß der Rotationskörper (41) axial in der Kammer (40) so verschiebbar ist, daß er sich mit seinen Stirnflächen an den Endflächen der Kammer anlegen kann,
daß Rotationsflächen des Rotationskörpers (41) mit Gegen flächen der die Kammer (40) bildenden Teile des Rotations gehäuses (35) und des Kolbens (37) zwei gegensinnig zwi schen jeweils einem Anfang und einem Ende verlaufende Scherkanäle bilden, die sich in Umfangsrichtung erstrecken,
daß die Scherkanäle an ihrem Anfang jeweils mit einem Re servoir (52) verbunden sind und an ihrem Ende jeweils in einen Verbindungskanal oder einen Ringspalt (54) münden, der zwischen einer der Stirnflächen des Rotationskörpers (41) und der anliegenden Endfläche der Kammer (40) endet,
daß das Volumen des Reservoirs (52) größenveränderlich ist,
und daß Steuerelemente zum wechselseitigen Verschließen und Öffnen der Verbindungen zwischen den Anfängen der beiden Scherkanäle und dem Reservoir (52) in Abhängigkeit von der relativen Drehrichtung des Rotationskörpers gegenüber dem Rotationsgehäuse und dem Kolben vorgesehen sind.
