Cruise Control Servo: Description and Operation

This unit is a variable position diaphragm assembly that positions the throttle when the cruise control system is activated. Controlled vacuum from the regulator is applied to the servo and atmospheric pressure moves the diaphragm and linkage, positioning and holding the throttle to desired cruise speed.
