  • Power steering hydraulic system with a low pressure expansible reservoir
    Patent number: 4203287
    Abstract: A power steering system has a pump, a steering gear and pressure and return passages. The pump does not include a cover member which conventionally provides space for the storage of excess fluid. The return passage has an expansible chamber included therein which accommodates the fluid volume change within the system resulting from fluid temperature changes thus permitting hermetic sealing of the system. An aspirator can also be included within the expansible chamber to improve the inlet pressure condition at the pump.
