Elantra GLS Wagon L4-2.0L (2000)
Steering Gear: Description and Operation
LEFT TURN (COUNTERCLOCKWISE)
The power steering oil pump generates the oil pressure and the oil enters into the rotary valve. And the torsion bar is twisted by the force between the
steering wheel rotation and the resistance of the tire to the ground. At a high speed of vehicle, the oil passing the rotary valve comes into the solenoid
valve through the lower hole and goes out through the upper hole flowing the connecting space of piston. At this time the piston goes back due to the
spring force overcoming the solenoid plunger. The oil flows through the space between the piston and side wall. And then the oil flows again into the
rotary valve and finally is drained to reservoir through the drain hole between the rotary valve and the torsion bar. Therefore the oil pump pressure
does not affect the steering effort. As the vehicle speed decreases the hole of piston connecting the left chamber and right chamber is gradually closed
as the oil pressure produced by oil pump is delivered to the left chamber. Therefore, the steering effort is reduced.
RIGHT TURN (CLOCKWISE)
