end cover.
As the high pressure area is filled, oil flows under the vanes in the rotor slots, forcing the vanes to follow the inside surface of the cam ring. As the
vanes reach the restricted area of the cam ring, oil is forced out from between the vanes. When excess oil flow is generated during high-speed
operation, a regulated amount of oil returns to the pump intake side through a flow control valve. The flow control valve reduces the power required to
drive the pump and holds down temperature build-up.
When steering conditions exceed maximum pressure requirements, such as when the wheels are turned against the stops, the pressure built up in the
steering gear exerts pressure on the spring end of the flow control valve inside the pump. The 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 power steering pump.
Under normal power steering pump operating conditions, 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 be maintained without pump assistance.
However, under these conditions, steering effort will be significantly increased.
