Patent FR-2547621-A1 (FR)
Title: Gear pump or motor with axially pressurised bearing members
Inventor: FAUSTEN WILHELM
IPC: F04C15/00
Filed: 1984-04-27
Abstract: The gear pump or motor is lubricated by the pump or drive medium and comprises a housing (1-3) with inlet and outlet connection and contg. at least two externally meshing gears (4,5) on shafts carried in bearing members (8,9). At the axially outer faces of these members, sealed leak oil spaces (12) and pressure chambers are arranged, the latter providing axial pressure compensation. The main shaft (6) extends through a housing recess (10) into the drive or output compartment. An axial bore (14) in the other shaft (7) connects the spaces. Leak oil from the spaces is discharged  (e.g. to the engine sump) via a connection near the recess (10), e.g. via an axial bore (15) in the shaft (6) which may contain a throttle (16). Leak oil pressure may be monitored by a sensor (22).
Patent FR-2563879-A1 (FR)
IPC: B60K5/12
Filed: 1984-05-04
Abstract: The invention relates to an antivibration support to be inserted between the frame and the engine of a vehicle. The support comprises two deformable chambers filled with liquid, separated by a deformable partition, and communicating with one another through a restricted passage, namely an operating chamber whose lateral wall forms a support and joins two rigid parts fixed respectively to the frame and to the engine, and a compensating chamber. When abnormally high thrusts are applied to the engine, the deformations of the wall are limited by abutment, against a ring immersed in the operating chamber and borne by the first rigid part, of a central foot fast to the second rigid part, and passing with clearance through the ring and/or of an overlapping sole terminating this foot.
