Swash plate design hydrostatic axial piston machine for e.g. axial piston motor for adjusting delivery volume of pump, has recess formed corresponding to groove and extending in swivel direction and ending in distance to edges of surface

摘要

The machine has a slidingly mounted swivel disk (20) designed as a swingable mounted swivel cradle and comprising a cylindrical bearing surface (22) with which the swivel disk pivots in a bearing shell. The bearing shell is formed with a hollow cylindrical surface. The surface comprises a recess (27), which supplies hydraulic fluid via an inlet channel (44). The recess is formed corresponding to a groove (28) with an ornamentation-similar basic pattern-shaped curve, and extends in a swivel direction over the surface and ends in certain distance to edges (34, 36) of the surface.
