摘要： PURPOSE:To enable a stale control to be attained by comparing the present engine speed with the preset idle speed and controlling a negative pressure actuator for driving a throttle valve to be driven by a negative pressure or atmospheric pressure introducing mode. CONSTITUTION:A negative pressure actuator 1 for controlling an idle speed opens and closes a throttle valve 7 through an idle adjusting lever 4 by an output of the negative pressure actuator 1, and its negative pressure chamber performs supply and cutoff of a negative pressure by the first negative pressure selector valve 2 provided interposing in a negative pressure hose 6. While the second negative pressure selector valve 3, serving as a three-way valve, is provided interposing between the first negative pressure selector valve 2 and the negative pressure chamber, performing the selection of introducing the negative pressure and the atmospheric pressure. Now when an engine speed reaches not more than or not less than the preset idle speed, the second negative pressure selector valve 3 is controlled selecting a mode of introducing the negative pressure or the atmospheric pressure and controlling the negative pressure actuator 1 to be driven.
