VALVE-CONTROLLED POSITIVE DISPLACEMENT MACHINE

A valve-controlled hydrostatic positive displacement machine (DDU) is proposed, with a plurality of cylinder-piston units which are each activatable or deactivatable, via at least one low-pressure valve and via one high-pressure valve, for adjusting a volume flow of the positive displacement machine...

Beschreibung
Zusammenfassung:	A valve-controlled hydrostatic positive displacement machine (DDU) is proposed, with a plurality of cylinder-piston units which are each activatable or deactivatable, via at least one low-pressure valve and via one high-pressure valve, for adjusting a volume flow of the positive displacement machine. According to the invention a valve body of the high-pressure valve is embodied as a valve slide, and operative faces acted upon in or counter to a displacement direction are essentially pressure-balanced.
