Power Steering Pump: Description and Operation
POWER STEERING (P/S) PUMP
The power steering pump is a vane type and is driven by the V-ribbed belt from the crankshaft.
FLOW CONTROL VALVE
As the discharge rate of the Power Steering (P/S) pump increases in proportion to the pump revolution speed, a flow control valve is added to control
it so that the optimum amount of fluid for steering operation is supplied according to the engine speed (driving condition). Described below is its
operation at different engine speed.
When Idling
The fluid discharged from the pump is supplied through the clearance around the rod in orifice A1 to the gear box.
