ABSTRACT:
A diaphragm assembly is linked to an engine throttle valve to control vehicle speed in accordance with applied fluid pressure. A speed sensor angularly positions a shaft in accordance with vehicle speed. Fluid pressure is modulated in accordance with the shaft position to control the diaphragm assembly. Momentarily depressing a button actuates a clutch assembly comprising a friction disc, a bifurcated spring and a tapered cam so that the vehicle speed is maintained at the speed the vehicle is travelling at the time the button is depressed.
