Abstract

Ein Hydrauliksystem weist einen hydraulischen Motor (10), dessen Einlaß über eine Zuführleitung (12) an eine Druck­ quelle (22) und dessen Auslaß über eine Rückführleitung (14) an eine Rücklaufdruckquelle (24) angeschlossen sind, und ein druckgesteuertes Ventil (40) auf, das bei einem bestimmten Druck in der Rückführleitung (14) die Zuführleitung (12) unterbricht, und nachfolgend in eine weitere Stellung ver­ schiebbar ist, in der der Einlaß des hydraulischen Motors (10) mit der Rücklaufdruckquelle (24) verbunden ist.
