Chapter 8. Power assisted steering system.
SECTION 1. GENERAL DESCRIPTION
The hydraulics of this power-assisted steering system are actuated by a specially designed steering
valve system.
Non Load reaction valve blocks the L,R cylinder ports in neutral condition and does not transmits the
reaction load of the tire to the steering wheel in neutral.Generally the system is used for the vehicles
that treat heavy equipment or low speed traveling.
Hydraulic circuit consists of Independent system.
The oil from tank flows into gear pump of orbitrol via filter,and the quantity of oil in the proportion
to the rotations of steering wheel flows into steering Cylinder Via "R"-port at right turn and via "L"-
port at left turn.
As follow figure shows components composition of power steering system on the vehicle with the
Orbitrol
