Abstract

Die Erfindung betrifft ein hydrostatisches Triebwerk (7), das als Verstellmaschine mit einem stufenlos verstellbaren Verdrängervolumen ausgebildet ist und als Pumpe und Motor betreibbar und mit einem Verbrennungsmotor (2) trieblich verbunden ist, wobei das Triebwerk (7) im Pumpenbetrieb mit einer Saugseite Druckmittel aus einem Behälter (9) ansaugt und in eine zu mindestens einem Verbraucher (V) geführte Förderleitung (10) fördert und wobei das Triebwerk (7) im Motorbetrieb als hydraulischer Starter zum Starten des Verbrennungsmotors (2) ausgebildet ist, wobei dem Triebwerk (7) im Motorbetrieb an der Saugseite Druckmittel aus einem Druckmittelspeicher (25) zuführbar ist. Das Triebwerk (7) ist mit einer Ausschwenkfeder (55) versehen ist, mittels der bei abgestelltem Verbrennungsmotor (2) eine das Verdrängervolumen des Triebwerks (7) steuernde Verdrängervolumenstelleinrichtung (50) in die Stellung mit maximalem Verdrängervolumen beaufschlagt ist, so dass ein direkter Startvorgang des Verbrennungsmotors (7) durch den Motorbetrieb des Triebwerks (7) ohne zeitlich unmittelbar vorheriges Verstellen der Verdrängervolumenstelleinrichtung (50) des Triebwerks (7) erfolgt.
