Cruise Control Systems: Operation: Servo

Servo consists of an actuator motor, safety magnetic clutch, control arm and a position sensor. When servo receives a signal from CCM, it engages safety magnetic clutch and activates motor. Motor causes control arm to move, which will open or close engine throttle valve.

When motor rotates forward, control arm also rotates (via safety magnetic clutch, gears and drive shaft). Control arm pulls a cable connected to engine throttle valve and opens valve accordingly. When motor rotates in a reverse direction, control arm also rotates in a reverse direction and engine throttle valve closes.
