Steering: Description and Operation

1982 CORVETTE
Power steering equipment consists of a recirculating ball type steering gear and linkage to which a hydraulic power mechanism has been added as part of the steering linkage. The hydraulic mechanism furnishes additional power to assist the manual operation so that the turning effort at the steering wheel is greatly reduced. The hydraulic mechanism consists of three basic units: a hydraulic pump and reservoir, a control valve, and a power cylinder.
