Sliding piston joint of a hydrostatic piston machine |
摘要 |
A sliding piston joint of a hydrostatic piston machine has a piston having a recess or cavity and a sliding shoe having a head portion receivable into the recess or cavity of the piston so as to support the latter. The sliding shoe has a base portion having a surface which faces away from the piston and faces toward a hydrostatic pressure zone generated during operation of the machine. The head portion of the sliding shoe and the piston have surfaces which are in sliding contact with one another. A throughgoing passage extends through the sliding shoe so that a portion of working fluid flows from the hydrodynamic pressure zone to the contacting surfaces of the sliding shoe and the piston to thereby relieve the latter.
