Power Steering Pump: Description and Operation
POWER STEERING PUMP
DESCRIPTION
DESCRIPTION
Hydraulic pressure for the power steering system is provided by a belt driven power steering pump. The pump shaft has a pressed-on drive pulley that
is belt driven by the crankshaft pulley.
OPERATION
The power steering pump is a constant flow rate and displacement, vane-type pump. The pump internal parts operate submerged in fluid. The flow
control orifice is part of the high pressure line fitting. The pressure relief valve inside the flow control valve limits the pump pressure. The reservoir is
attached to the pump body with spring clips. The power steering pump is connected to the steering gear by the pressure and return hoses.
Note: Power steering pumps have different pressure rates and are not interchangeable with other pumps.
