Turning of the steering wheel is converted into linear
travel through the meshing of the helical pinion
teeth with the rack teeth. Power assist steering is
provided by an open center, rotary type control valve
which directs oil from the pump to either side of the
integral rack piston.
Road feel is controlled by the diameter of a torsion
bar which initially steers the vehicle. As required
steering effort increases, as in a turn, the torsion bar
twists, causing relative rotary motion between the
rotary valve body and the valve spool. This move-
ment directs oil behind the integral rack piston,
which, in turn, builds up hydraulic pressure and
assists in the turning effort.
