Abstract
A power steering valve system includes an input shaft and an output shaft which are aligned on a common axis, and also includes a control valve mechanism which is located offset from the axis in order to reduce the overall length of the valve system. The control valve mechanism includes a spool valve, a displacement of which from its neutral position controls the flow of a hydraulic oil from an oil pump to or from a power cylinder to assist in directing the steerable road wheels in a given direction. The input and output shafts are operatively associated with a motion translating mechanism which translates the magnitude of a relative torsion between the two shafts into a linear displacement. The motion translating mechanism is operatively associated with the spool valve to displace it from the neutral position in accordance with the magnitude of relative torsion between the two shafts.
