An air induction control device for an internal combustion engine is composed of an air passage for communicating upstream and downstream sides of a throttle valve in an intake passageway when opened, a valve member movably disposed in the air passage to open the air passage in response to pressure differential between the upstream and downstream sides of the throttle valve in the intake passageway, and a diaphragm member mechanically connectable to the valve member so as to open the air passage in response to vacuum prevailing in the intake passageway downstream of the throttle valve, thereby effectively controlling air induction to the engine, even when the throttle valve is closed during normal engine deceleration and at sudden engine deceleration or during operation of engine accessories at idle throttle state.

An air induction control device for an internal combustion engine having an intake passageway in which a throttle valve is disposed, comprising: means defining an air passage for communicating upstream and downstream sides of the throttle valve in said intake passageway when opened; a valve member disposed in said air passage and movable toward the downstream side thereof to open said air passage in response to pressure differential between the upstream and downstream sides of the throttle valve in the intake passageway; and a diaphragm member mechanically connectable to and separable from said valve member and movable to move said valve member so as to open said air passage in response to vacuum prevailing in the intake passageway downstream of the throttle valve.
