Abstract
A hydraulic drive system for use with a vehicle power steering pump has a hydraulic motor connected in series with a power steering mechanism and a bypass line extending in bypassing relationship with the motor. A bypass valve is disposed in the bypass line to control the flow through the bypass line such that, when a steering force applied to a vehicle steering wheel is increased, the bypass flow is substantially in proportion to the steering force.
