Abstract

Offenbart ist eine hydraulische Kolbenmaschine, insbesondere eine Doppeltaumelscheibenpumpe, mit einer Vielzahl von Kolben, die in einem Zylinder verschiebbar geführt sind, und die jeweils einen Arbeitsraum begrenzen, in den Druckmittel über ein Saugventil zuführbar und aus dem Druckmittel über ein Druckventil abführbar ist. Der Kolben ist von einem Druckausgleichs-Druckmittelströmungspfad durchsetzt, der erfindungsgemäß durch ein in den Kolben eingesetztes Kapillarrohr gebildet ist.
