Power Steering Pump Speed Sensor: Description and Operation
General Description
Power Steering Speed Sensor
Power Steering Speed Sensor
The power steering speed sensor is a trochoid-rotor, hydraulic pump combined with a relief valve and a one- way valve. It is driven by the speedometer
gear shaft which in turn is driven by a helical gear on the differential,
The power steering speed sensor turns only when the car is moving, controlling the gain control valve.
The constant pressure is generated by the pressure control valve.
This pressure is used as a reference pressure for the response to the car speed. By introducing this pressure to the power steering speed sensor through
the sensor orifice, the pressure downstream of the orifice is changed according to the speed of the car.
This pressure is then used to operate the gain control valve.
