Abstract
A speed control actuator includes a diaphragm forming a movable wall of a variable pressure chamber. An output member is fixed to the diaphragm to impart diaphragm movement to a throttle valve of the automotive vehicle. Three solenoid valves are mounted on a common bracket and are disposed in the variable pressure chamber for controlling vacuum and atmospheric pressure into the chamber. Two of the three solenoid valves are normally biased open to assure disengagement of the actuator.
