ABSTRACT:
A system for hydrostatic pressure release of the rocker in the bearing box in an axial piston machine. The pressure-relief system includes slots in the rocker bearing box connected with axial passages through the pistons, pressure pockets in the guide shoes and passageways through the rocker. In order to render the forces in the pressure-relief system essentially constant and speed-independent, the pressure-relief devices of the rocker bearing and four individual slots, two of which are parallel to each other in the region of each of the two bearing surfaces on the rocker and which are connected to the pressure pockets in the guide shoes by the passageways through the rocker.
