The control valve consists of a rotor (which rotates
together with the steering shaft), a pinion (which is
-
connected to the rotor and torsion bar), and a sleeve
(which rotates together with the pinion) . Oil grooves C
and D are located in the rotor and sleeve to form oil flow
passages V, through V4 .
The pinion and rotor are meshed with adequate clear-
ance. They utilize a fail-safe design .
