(3) OPERATION
▶ During parking and low speed driving
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.
▶ In medium and high speed driving
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.
