ABSTRACT:
A compact construction for a vehicle steering gear is provided of the rotary valve type which utilizes a torque rod having an end connected to a worm shaft and the opposite end connected to a steering spindle wherein axial load oil pressure on the torque rod is minimized to avoid breakage. This is accomplished by hydraulic circuitry which routes high inlet pressure to the valve housing directly to the valve grooving instead of to an end of the valve body where it would exert an axial force on the torque rod.
