Swivel motor

摘要

Swivel motor, comprising a cylinder and a motor shaft as well as end caps which define a working space. A number of ribs on the inner surface of the cylinder and the same number of vanes on the motor shaft subdivide the working space into working chambers which are alternately supplied with hydraulic medium. Seals inside grooves in the ribs and vanes hydraulically separate the working chambers from one another. The swivel motor is characterised in that the seals are designed in one piece as a disc body, and there is an intermediate space in each case between the seals and the groove side walls in the static rest position, the disc body performing a sealing function via its end faces, its surfaces determining the disc height, and a side wall during the swivel motor operation.
