Taurus V6-182 3.0L VIN 1 FI Flex Fuel (1997)
^
The fluid in the opposite end of the power cylinder is forced to the control valve and back to the pump reservoir.
^
When the driver stops applying steering effort, the valve is returned back to a centered position by the torsion bar.
^
When this occurs, pressure is equalized on both sides of the piston and the front wheels tend to return to a straight-ahead position.
VAPS
The rotary design control valve directs fluid flow using relative rotational motion of the power steering gear input shaft and control and valve
sleeve. When the steering wheel is turned, resistance of the wheels and the weight of the vehicle causes a torsion bar to deflect.
^
The deflection changes the position of the valve spool and sleeve ports, directing pressurized fluid to the appropriate end of the power
cylinder.
^
The difference in pressure forces on the piston helps move the steering gear sector shaft to assist turning effort.
^
The piston is attached directly to the steering gear sector shaft. The steering gear housing functions as the power cylinder.
