ABSTRACT:
The hydrostatic piston machine is provided with hydrostatic bearing pockets at least one of which is provided with an unthrottled flow of high-pressure medium while at least one other pocket is provided with a throttled flow of high-pressure medium. And the pockets are sized relative to each other so that the pockets receiving the unthrottled flow compensate for 70% to 95% of the force on the bearing while the pockets receiving the throttled flow compensate for 30% to 5% of the bearing forces applied.
