This paper discusses, in combination with an internal combustion engine, a system for regulating engine speed by regulating the air flow across a throttle valve in an air intake passage. It comprises an engine air intake valve and means of sensing an operating variable representative of engine speed and sending an electrical signal representative of the engine speed to the engine air intake valve. The engine air intake valve comprising a common housing having a first actuator chamber and a second valve chamber, a rotary electrical actuator mounted in the first chamber, the actuator comprising an electrical rotor, the second valve chamber defining an air passageway having an inlet on one side of the throttle valve and an outlet on the other side of the throttle valve, the rotor comprising an axial extension having a cylindrical side surface movable rotationally along a cylindrical surface of the second valve chamber, and a flow port in the cylindrical side surface of the second valve chamber intermediate the inlet and outlet thereof. The area of the flow port is determined by the rotational position of the axial extension of the rotor across the flow port in response to the electrical signal generated by the sensing means.
