速機の油圧制御装置。[Scope of Claim for Utility Model Registration] A driving pulley and a driven pulley each consisting of a fixed conical plate and a movable conical plate, a V-belt wound between both pulleys, and a fixed conical plate that is attached to the movable conical plate when hydraulic pressure is applied. A driving pulley cylinder chamber and a driven pulley cylinder chamber are formed on the driving pulley and the driven pulley, respectively, so as to apply a pressing force in a direction that brings the plate closer to the plate, and an oil drain that is movable in the axial direction integrally with the movable conical plate of the driven pulley. a pressure correction chamber for centrifugal hydraulic pressure correction formed by;
In a hydraulic control device for a continuously variable transmission, the oil passage that supplies oil to the pressure compensation chamber can supply oil when the gear ratio is smaller than a predetermined value, and when the gear ratio is larger than the predetermined value. A hydraulic control device for a continuously variable transmission, characterized in that the hydraulic control device is configured to be shut off.
