Abstract
A power steering apparatus includes a power steering fluid supply pump which is driven through a clutch. A sensor detects changes in vehicle speed and effects operation of the clutch to decrease the rate at which the pump is driven in response to an increase in vehicle speed. When the vehicle speed exceeds a predetermined speed, the clutch is disengaged and the pump is not driven. When the clutch is disengaged, the steerable vehicle wheels are turned without power assist.
