Abstract
Offenbart ist eine Kolbeneinheit einer Radialkolbenmaschine. Die Kolbeneinheit hat einen Stufenkolben und eine Rolle bzw. einem Rollenkörper. In einem Anlagebereich zwischen dem Stufenkolben und der Rolle ist eine hydrostatische Druck- bzw. Kraftentlastung vorgesehen, die dort ein Druckfeld bildet. Der Stufenkolben hat benachbart zur Rolle zwei Halteabschnitte. Erfindungsgemäß sind diese elastisch und/oder der Stufenkolben hat in einem Bereich seiner Stufe zwischen seinem Hauptabschnitt und den Halteabschnitten je eine Schwächung. Damit können sich die Halteabschnitte an die Rolle schmiegen und eine Spalt bzw. Abstand dazwischen verringern.
