Claims

[Scope of utility model registration request]

A control piston that receives the tip of a hydraulic pressure setting spring and increases the strength of the hydraulic pressure setting spring by advancing the piston is provided so as to be able to move forward to a regulated position, and the hydraulic pressure of the oil supply circuit for the hydraulic clutch in a hydraulic clutch type transmission is controlled according to the control piston. A hydraulic control device comprising a pressure regulating valve configured to act behind a control piston through a throttle, the throttle being configured as a throttle with a variable degree of restriction, and a temperature regulating valve for sensing the temperature of hydraulic oil. A hydraulic control device for a hydraulic clutch type transmission, characterized in that a sensor is provided, and the throttle and the temperature sensor are connected in such a way that the higher the temperature of hydraulic oil, the higher the degree of restriction of the throttle.
