Abstract
An idling speed control device of an internal combustion engine having a bypass passage which interconnects the intake passage located upstream of the throttle valve to the intake passage located downstream of the throttle valve has a flow control valve device arranged in the bypass passage and actuated by a stepper motor for controlling the amount of air flowing within the bypass passage to maintain the idling speed of the engine at a predetermined speed. The flow control valve device comprises a valve chamber having an air inlet opening and an air outlet opening which is connected to the intake passage located downstream of the throttle valve. The air inlet opening is formed on the inner bottom wall of the valve chamber and connected via the bypass passage to the intake passage located upstream of the throttle valve.
