    valve varies according to the vehicle speed.

OPERATION PRINCIPLE

During Parking (When Turning The Steering Wheel To The Right)

Nissan Maxima. OPERATION PRINCIPLE

  1. Power steering solenoid valve is closed while a vehicle is stopped.
  2. Pinion "1R", "2R" and "3R" are closed depending on steering torque of steering wheel.
  3. Oil pressure "P" in the gear housing assembly is the sum of oil pressures occurring in "2R" and "3R". This
    results in a light steering force because of high pressure.

During High-speed Operation

Nissan Maxima. During High-speed Operation

  1. Power steering solenoid valve is opened during high-speed operation.
  2. Pinion "1R", "2R" and "3R" are closed depending on steering torque of steering wheel.
  3. Oil pressure "2R" does not occur because the power steering solenoid valve is on full throttle.
  4. Oil pressure "P" in the gear housing assembly includes only oil pressure occurring in "3R" and results in a
    heavy steering force.
