Abstract

PURPOSE: To automatically obtain an optimal transmission ratio through simple operation, by regulating the degree of opening of a throttle valve of an engine to control a changing servomotor and a clutch servomotor.
CONSTITUTION: A main servomotor MS comprises a spool valve 35 fitted in the central part of a valve hole 34 provided in a control casing 33, and a right and a left input pistons 36, 37 fitted in the right and left parts of the valve hole 34. The cam face of a rotary cam 40, which moves in connection with the throttle valve of the engine, is in contact with the outer end face of the left input piston 36. The lower end of a restricting plate 41 is in contact with the outer end face of the right input piston 37. An oil chamber b communicates with a left oil chamber e of a servo-cylinder 48. An oil chamber c communicates with a right oil chamber f of the servo-cylinder 48. An output piston 54, which defines the oil chambers e, f, is coupled to the hydraulic changing servomotor CHS and the clutch servomotor CLS through an operating arm 132, an operating cam 131 and a clutch operating rod 135.
