Abstract

PURPOSE: To prevent overrun of an output shaft by applying a specified fluid signal to a ration control valve when the rotating speed of an output shaft reaches a present value to enlarge a torque transmission ratio.
CONSTITUTION: A ratio control valve 10 for controlling the ratio of control oil pressure of the primary pulley control valve 8 to that of the secondary pulley control valve 7 is disposed between both valves 7, 8, and a fluid signal from car velocity detection means 12 connected to a governor 11 is input to the ratio control valve 10. In this arrangement, when the rotating speed of an output shaft reaches a preset value, a specified fluid signal is applied from the car velocity detection means 12 to the ratio control valve 10 to enlarge the torque transmission ratio, whereby the rotating speed of the output shaft is decreased to prevent overrun of the output shaft.
