Abstract

Schwenkmotor, 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 (19,17) 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 zum ersten Druckmediumanschluss gehörigen Arbeitskammern sich mit denen abwechseln, die mit dem zweiten Druckmediumanschluss verbunden sind, wobei zwischen mindestens zwei Arbeitskammern die mit verschiedenen Druckmediumanschlüssen verbunden sind mindestens ein Druckbegrenzungsventil (36) innerhalb des Schwenkmotors angeordnet ist.
