Abstract (en)

[origin: US4527966A] An apparatus for an hydrostatic compensation of hydraulic pumps and motors of gear type in which two intermeshing gears are mounted on shafts which are supported by bearings or journal-bearings which can slide within the cavity of a pump or a motor housing closed on both lateral sides by covers. Compensation chambers between the bearings and the covers are delimited by grooves respectively provided in the faces facing bearings and covers. A part of one side of the grooves provided in the bearings is in alignment with one of the grooves provided in the corresponding cover. Deformable tightness seals are arranged in said grooves.
