Prelude L4-2.2L SOHC (1994)
As the car is driven, the rotors start turning and the fluid returns to the reservoir, reducing the fluid pressure at the gain control valve. Therefore, the
gain control valve begins to move to the right. The orifice resistance on the pump and reservoir sides is appropriately balanced, with the result that the
reaction chamber is in the medium range and the steering resistance is moderate.
When the car is moving at high speed, the sensor reduces the pressure further and the gain control valve moves further to the right. The orifice
pressure on the pump side is low and the pressure on the reservoir side is high, the fluid pressure in the reaction chamber is also high giving the
steering wheel less assist.
