C: FLUID PUMP AND RESERVOIR TANK
1. ALL MODELS EXCEPT 3.0 MODEL
The fluid pump is a vane type driven by the engine via belt.
The reservoir tank is mounted on the vehicle body.
The fluid pump incorporates the flow control valve, pressure-sensitive valve, and relief valve, each
performing the following functions:
! The flow control valve regulates the flow rate of discharged fluid to a constant level irrespective
of the engine speed.
! The pressure-sensitive valve returns the fluid to the reservoir tank when there is no steering in-
put.
! The relief valve protects the system from an excessively high pressure which may occur, for ex-
ample, when the steering wheel is turned all the way.
