Power Steering Pump Speed Sensor: Description and Operation
One-Way Valve
One-Way Valve
Pressure develops at the power steering speed sensor inlet because the power steering speed sensor is pumping faster than the fluid can be supplied. To
compensate for this, the outlet and inlet ports are connected internally by a passage containing a one-way valve that lets output fluid recirculate to the
inlet port to equalize pressure.
