ABSTRACT:
A toroidal type transmission system includes a toroidal transmission mechanism, an actuator for continuously vary a transmission ratio by varying the angle of inclination of power rollers of the toroidal transmission mechanism, a forward-reverse changeover mechanism provided on the input side of the transmission mechanism for changing the direction of input rotation inputted to the toroidal transmission mechanism, a first control valve for controlling a fluid pressure supplied to the actuator only when the input rotation is in the forward direction, a second control valve for controling a fluid pressure supplied to the actuator only when the input rotation is in the reverse direction, a reverse detecting means for detecting the direction of the input rotation, and a selector valve for selecting the first or second control valve in dependence on the direction of rotation detected by the detecting means.
