Abstract
Offenbart ist eine hydraulische Kolbenmaschine, bei der eine Vielzahl von Kolben (4) über jeweils eine Feder (6) in Rückführrichtung vorgespannt ist. Die Feder (6) taucht in eine Axialausnehmung (28) des Kolbens (4) ein, wobei ein außerhalb der Feder (6) liegender Ringraum des Kolbens (4) über einen definierten Verbindungsquerschnitt (46) mit einer Zylinderöffnung (12) verbunden ist.
