STEERING SYST EM
1) When steering wheel is fully turned or during low-
speed driving :
As a large current flow is supplied to the solenoid, the
solenoid plunger moves right while the spool valve,
unitized with the plunger, is pushed right . The power
steering reaction chamber and oil reservoir tank are
connected by a path, making the reaction pressure 0
kPa (0 kg/cm', 0 psi) . In this condition, the reaction
pressure does not work on the reaction piston, nor does
the reaction piston operate . So, light, effortless steering
as with conventional power steering, can be enjoyed .
