ABSTRACT:
A hydraulic power steering system has a steering valve which operates in accordance with steering input signals generated by a steering wheel operated metering pump and follow-up signals generated by a pair of follow-up cylinders to effect a desired turn. The steering valve acts in response to a relatively large signal, representing a desired sharp or full turn, to interrupt or block the follow-up signal whereby sharp turns may be accomplished without requiring as many turns of the steering wheel as would be necessary if follow-up flow were nullifying the input signal.
