ABSTRACT:
A reaction mechanism of a hydraulic control valve including a control valve for regulating hydraulic pressure by controlling hydraulic fluid disgorged from a pump, an input member mechanically connected to the control valve and operated by a driver, the input member having a smaller diameter portion and a larger diameter portion, an annular reaction regulating member into which the smaller diameter portion of the input member is slidably inserted, a diameter of the annular member being equal to or less than the larger diameter portion of the input member, a biasing member for normally urging the annular member toward the larger portion of the input member, and a member for supplying the hydraulic pressure regulated by the control valve into an area between the annular member and the large diameter portion of the input member to displace the annular member from the larger diameter portion of the input member against the biasing member.
