Power steering gear with integral rotary valve for directing hydraulic pressure fluid to and from a piston nut and in which a sector gear actuated plunger provides a drag load on piston nut screw so that the valve body will be grounded and the valve spool will be immediately turned relative to the valve body on rotation of the stub shaft before there is lash take-up between the threads of the piston nut and screw which drivingly connect the valve body to the piston nut and sector gear.
