Abstract
An idle speed control valve for use in controlling the idle speed of an engine wherein the control valve utilizes a pilot valve to control a valve lift assist force generated by a pressure acting on a differential area associated with the valve. The control valve is actuated in response to a desired speed signal generated by sensed engine conditions as compared to the actual speed of the engine.
