Abstract

Offenbart ist eine ventilgesteuerte Kolbenmaschine - insbesondere Radialkolbenmaschine DVR - mit mehreren Kolben-Zylinder-Einheiten und mit einem Niederdruckanschluss und mit einem ersten Hochdruckanschluss. Jede Kolben-Zylinder-Einheit hat ein mit dem Niederduckanschluss verbundenes Niederdruckventil und ein mit dem ersten Hochdruckanschluss verbundenes erstes Hochdruckventil. Dabei ist an der Kolbenmaschine ein weiterer Hochdruckanschluss vorgesehen, wobei jede Kolben-Zylinder-Einheit ein damit verbundenes weiteres Hochdruckventil hat. Das Niederdruckventil und die Hochdruckventile sind aktiv steuerbar.
