Abstract

Eine hydrostatische Maschine (1) weist eine in einem Gehäuseraum drehbar gelagerte Zylindertrommel auf, in der Arbeitszylinder ausgebildet sind, in welchen Arbeitskolben bewegbar sind. Ein Steuerteil (2) dient zum Verbinden der Arbeitszylinder der Zylindertrommel mit zwei Druckfluidanschlüssen (4, 5), wobei einer der Druckfluidanschlüsse (4; 5) einen Hochdruck und der jeweils andere Druckfluidanschluß (5; 4) einen Niederdruck führt. Ferner sind zwei unabhängige Spülventile (18, 19) vorgesehen, die jeweils einem der Druckfluidanschlüsse (4, 5) zugeordnet sind. Jedes der Spülventile (18, 19) verbindet den zugeordneten Druckfluidanschluß (4, 5) mit dem Gehäuseraum, wenn der Druck in dem zugeordneten Druckfluidanschluß (4, 5) einen vorgegebenen Schwellwert unterschreitet.
