御弁。 A cylindrical outer valve member having a radial passage formed therein, and a cylindrical inner valve fitted within the outer valve member for relative rotation and having a radial passage formed at a position corresponding to the passage. In the pressure control valve, the pressure control valve is provided with a member and performs communication cutoff control between the oil pump and the tank by relatively rotationally displacing the two valve members, wherein a channel is provided at an opening on the outer surface side of the radial passage of the inner valve member. A pressure control valve characterized in that the bottom surface of the channel is a cylindrical surface.
