<p>The hydraulic power steering apparatus of the present invention has plungers being installed movably at part of a casing of a hydraulic control valve and a reaction chamber being formed at one side of said plungers, and varies hydraulic pressure to be supplied to a hydraulic pressure reacting portion for generating restriction force corresponding to supplied hydraulic pressure according to vehicle speed and quantity of relative movement between a valve body and a casing of hydraulic control valve, thereby the supplied hydraulic pressure being increased as the vehicle speed becomes higher and steering angle becomes larger.</p> |
