The device (20) has a main pump (24) i.e. rotary pump, serving to feed hydraulic motors (26A, 26B) with fluid. An auxiliary pump (25) serves to maintain a minimum fluid pressure in an auxiliary duct. The main pump and the auxiliary pump are actuated jointl...

The circuit has a motor assembly (230) connected to a hydraulic pump (212) by a return line (206). A force-feeding pump (214) deducts fluid in a fluid reservoir and forcedly supplies the fluid to the circuit at a level of a series line (204). An exchange b...

Braking system for a vehicle with at least a hydraulic motor, supplied by a close circuit with a variable capacity pump. The braking system comprises both friction braking and hydrostatic braking systems. Braking command means are configured to command fri...

Hydraulic circuit for the hydrostatic transmission of a vehicle comprising at least one hydraulic motor (10), two main lines (12, 14), a parking brake (30, 32) having braking means, release control means (38) for supplying the release chamber from a first ...

The system consists of brake discs (14, 16) connected to the rotor (10) and stator (12), and a piston (18) that moves between brake application and release positions and is normally urged towards the application position by a spring (20). The piston is loc...
