ONE-WAY VALVE (IN POWER STEERING SPEED SENSOR)
When the vehicle is moving at high speed, negative pressure develops at the 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.
RELIEF VALVE (IN POWER STEERING SPEED SENSOR)
When the vehicle is moving in reverse, the power steering speed sensor also turns backward and pumps fluid in the opposite direction. To avoid
building up pressure in the reaction chambers that would increase steering effort while driving in reverse, the inlet and outlet-ports are connected by a
second internal passage containing a relief valve that allows the fluid to recirculate.
