Abstract

Schwenkmotor (1) mit mehreren Arbeitskammern (15,17) und einem 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 (33) verbunden sind, sich mit denen abwechseln, die mit dem zweiten Druckmediumanschluss (35) verbunden sind, wobei mindestens zwei Arbeitskammer unterschiedlicher Zuordnung der Druckmediumanschlüsse mit einem Druckkompensationselement (37) verbunden sind und das Druckkompensationselement 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 verbunden ist und das Trennelement von entgegengesetzt wirksamen Federn (43,45) in einer Ausgangsstellung gehalten wird, wobei die Federkraftkennlinie von einer mehrere Federn umfassenden Federanordnung gebildet wird, die mindestens eine Schraubenfeder (45) und eine Elastomerfeder (69) aufweist, wobei für die Elastomerfeder mindestens ein Volumenkompensationsraum vorliegt.

Figure imgaf001
A swing motor (1) having a plurality of working chambers (15,17) and a composite system between the working chambers, which connects at least in pairs working chambers, wherein the arrangement of the connected working chambers is designed such that the working chambers, which are connected to the first pressure medium connection (33), alternate with those connected to the second pressure medium port (35), at least two working chambers of different association of the pressure medium ports are connected to a pressure compensating element (37) and the pressure compensating element is formed by a compensating space (39) provided by a movable separating element (39); 41), wherein in each case a partial compensation chamber (39a, 39b) is connected to at least one working chamber of a pressure medium connection and the separating element is held by oppositely acting springs (43, 45) in a starting position, wherein the spring force characteristic curve comprises a spring comprising a plurality of springs order is formed, which has at least one coil spring (45) and an elastomeric spring (69), wherein there is at least one volume compensation space for the elastomeric spring.
