Abstract

Die Erfindung betrifft eine Kolbenpumpe mit einem Kolben, der mit seiner Stirnfläche und einem Pumpenzylinder einen Arbeitsraum begrenzt, der über Rückschlagventile mit einem Hydraulikmediumsvorrat und mit einem Arbeitszylinder verbunden ist, welcher Kolben entgegen der Kraft einer Feder axial hin- und herberwegbar ist. Gemäß der Erfindung wird vorgeschlagen, daß der in den Arbeitsraum hineinragende Abschnitt des Kolbens mit einem Fortsatz mit geringerem Durchmesser versehen ist, der sich über einen Absatz an die Stirnfläche des Kolbens anschließt und der ein verdicktes freies Kolbenende mit einer dem Absatz zugewandten Dichtfläche aufweist, daß zwischen dem Absatz und der Dichtfläche wenigstens eine Ventilscheibe vorhanden ist, die dichtend in dem Pumpenzylinder geführt und durch die die Verbindung des Arbeitsraums zum Rückschlagventil verschließbar ist und die eine axiale Dicke aufweist, die kleiner ist als der Abstand zwischen der Dichtfläche und dem Absatz, so daß die Ventilscheibe zwischen dem Absatz und der Dichtfläche axial hin- und herbewegbar ist, wobei die Ventilscheibe mit wenigstens einer Durchbrechung versehen ist, durch die der Arbeitsraum mit dem zweiten Rückschlagventil verbindbar ist und die bei der Anlage der Ventilscheibe an der Dichtfläche geschlossen ist.
