Abstract

Die Kolben (5) einer hydrostatischen Maschine (1) sind in Zylindern (4) bewegbar und einer zyklischen Hubbewegung unterworfen. Ein Steuerkörper (12) weist eine Niederdruck-Steueröffnung (13) und eine Hochdruck-Steueröffnung (14) auf, um die Zylinder (4) zyklisch, alternierend mit einer Niederdruckleitung und einer Hochdruckleitung zu verbinden. Ferner weist der Steuerkörper (12) eine Zusatzöffnung (20) zum Beaufschlagen der Zylinder (4) mit einem vorkomprimierten Druckmedium auf. Erfindungsgemäß ist die Zusatzöffnung (20) mit einer geregelten oder gesteuerten Vorkompressionseinrichtung (23) verbunden, die durch eine Regel- oder Steuereinrichtung (24) so angesteuert wird, daß sich in den Zylindern (4) beim Übergang von der Niederdruck-Steueröffnung (13) zu der Hochdruck-Steueröffnung (14) ein kontinuierlicher, stetiger Druckaufbau einstellt.
