摘要： A device for biasing a cylinder drum in a variable-displacement axial piston machine against an associated slide valve member comprises a compression spring means, the axial piston machine having between the cylinder drum and the drive disk a synchronizing shaft which at each of its ends has a universal joint of the so-called tripoid type for angularly rigid but pivotable connection with the drum and disk, respectively, the synchronizing shaft furthermore being supported at each end approximately axially from the cylinder drum and drive disk, respectively, by a link pin. In order to provide a biasing device which requires less space adjacent the cylinder drum and thus allows a more compact design thereof, the compression spring means is mounted between a link pin bearing cup axially movably arranged in the center of the drive disk, and an abutment means, which is co-axial with and adjustably secured to said disk and the machine shaft associated therewith, such that the biasing force is applied to the drum from said abutment means under the intermediation of the synchronizing shaft.
