  • Patent number: 8001884
    Abstract: A swivel motor has a plurality of work chambers and a join system between the work chambers that joins the work chambers at least by pairs. The arrangement of the joined work chambers is carried out in such a way that the work chambers which are connected to the first pressure medium connection alternate with those which are connected to the second pressure medium connection. At least two work chambers associated with different pressure medium connections are connected to a pressure compensation element, and the pressure compensation element is formed by a compensation space that is divided by a movable dividing element. A partial compensation space is connected in each instance to at least one work chamber of a pressure medium connection, and the dividing element is held in an initial position by oppositely acting springs. The spring force characteristic is formed by a spring arrangement which comprises a plurality of springs and has at least one coil spring and one elastomer spring.

  • Patent number: 7992693
    Abstract: Presented is a vibration damper that includes an outer cylinder with a lateral surface, a pin-shaped fastening element that includes a stop surface, and a mounting coupled to the lateral surface. The mounting defines a through-hole that is configured to receive the pin-shaped fastening element and extends circumferentially with respect to the lateral surface. The mounting includes a formation that extends in a radial direction with respect to the cylinder. The formation cooperates with the outer cylinder to form a socket for the stop surface. The stop surface rests against the mounting in an axial direction of the pin-shaped fastening element.
