gear also exerts pressure on the spring end of the flow control valve. The end of the valve houses the pressure relief valve. High pressure lifts the relief
valve ball from its seat and allows oil to flow through a trigger orifice located in the outlet fitting. This reduces pressure on the spring end of the flow
control valve which then opens and allows the oil to return to the intake side of the pump. This action limits maximum pressure output of the pump to
a safe level.
Under normal power steering pump operating conditions, the pressure requirements of the pump are below maximum, causing the pressure relief valve
to remain closed.
In the event of a power steering pump drive belt failure, manual steering control of the vehicle can still to be maintained. However, under these
conditions, steering effort will significantly increase.
