<p>A hydraulic pressure control valve, wherein a valve body (12) having six oil grooves on its outer periphery at specified intervals is rotatably disposed in a cylindrical casing (10) having six oil grooves (11) on its inner periphery at specified intervals, and throttles are constructed on both sides of the respective oil grooves, thereby two throttling units each of which consisting of six throttles, are constructed and respective two throttles facing to each other in the radial direction among respective six throttles constructing respective throttling units have regions in which throttle areas do not substantially change until the relative angular displacement between the valve body (12) and the casing (10) reaches a predetermined magnitude. <IMAGE></p> |
