Power Steering Pump: Description and Operation
Vane Type Power Steering Pump W/Integral Reservoir
DESCRIPTION
The hydraulic pump is a submerged, vane-type design. Submerged pumps have a housing and internal parts inside the reservoir and operate
submerged in fluid.
OPERATION
There are two openings at the rear of the pump housing. The larger opening contains the cam ring, pressure plate, thrust plate, rotor and vane
assembly and the end plate. The smaller opening contains the pressure line union, flow control valve, and spring. The flow control orifice is part of
the pressure line union. The pressure relief valve, located inside the flow control valve, limits pump pressure.
