Operation
1. During parking and low speed driving
Return port
1) The SSPS control unit outputs nearly maximum electrical current.
2) The solenoid rod pushes the PCV spool to the right side.
3) The hydraulic pressure coming from pump is not supplied to the reaction device as the spool orifice is cut off.
4) The hydraulic pressure is cut off and the manipulation of steering wheel becomes lighter.
2. In medium and high speed driving
Return port
1) The shaft operating force of solenoid rod is reduced due to the reduction of output current from the SSPS control
unit.
2) The coil spring pulls the PCV spool toward solenoid valve to open it.
3) The hydraulic pressure from pump flows to pinion reaction area through orifice and applies reaction force to
reaction plunger.
4) At this time, the reaction plunger transmits the reaction force to V-groove in input shaft to provide heavy steerability.
