Hydrostatic driving mechanism for fitting to units like an engine cooling fan in an internal combustion engine uses a source of pressurized substance to feed a steering booster pump and a unit like an engine cooling fan.

摘要

A source of pressurized substance (2) feeds a steering booster pump (7) and a unit like an engine cooling fan with a hydrostatic driving mechanism (5) for a vehicle's internal combustion engine. The fan has its own hydromotor (13). Steering booster pump and fan are connected in series. The source of pressurized substance feeds the steering booster pump by overriding the fan.
