Abstract

Druckmittel betätigtes Aggregat, insbesondere Schwenkmotor (1), umfassend einen Zylinder (3) mit axial am Innendurchmesser verlaufenden Rippen (5), der endseitig von zwei Deckeln (11;13) verschlossen ist, eine Motorwelle (7) mit Flügeln (9), die dieselbe axiale Erstreckung besitzen wie die Rippen des Zylinders, wobei die Flügel der Motorwelle und die Rippen des Zylinders zusammen mit dem Zylinder, den Deckeln und der Motorwelle einzelne Arbeitskammern (15;17) bilden, einen ersten und einen zweiten Druckmediumanschluss (33;35) für zwei jeweils durch eine Rippe getrennte Arbeitskammern, ein Verbundsystem zwischen den Arbeitskammern, das mindestens paarweise Arbeitskammern verbindet, wobei die Anordnung der verbundenen Arbeitskammern derart ausgeführt ist, dass die Arbeitskammern, die mit dem ersten Druckmediumanschluss verbunden sind, sich mit denen abwechseln, die mit dem zweiten Druckmediumanschluss verbunden sind, wobei mindestens zwei Arbeitskammer unterschiedlicher Zuordnung der Druckmediumanschlüsse mit einem Druckkompensationselement (37) verbunden sind, das von einem Ausgleichsraum (39) gebildet wird, der von einem beweglichen Trennelement (41) unterteilt wird, wobei jeweils ein Teilausgleichsraum (39a;39b) mit mindestens einer Arbeitskammer eines Druckmediumanschlusses (33;35) verbunden ist.
