Claims

[Scope of utility model registration request]

An intake air amount control valve disposed in a bypass passage connected to the intake air passage bypassing a throttle valve disposed in the intake air passage of an internal combustion engine, the intake air amount control valve comprising a valve case and a valve fixed within the valve case. an annular partition wall, an air inlet and an air outlet provided in the valve case on both sides of the partition wall, and a temperature-dependent actuator housed in the valve case;
a valve rod coupled to the actuator and extending to the bulkhead at least upon extension; a valve member slidably fitted to the valve rod and capable of engaging the bulkhead; a groove in a direction, and as the valve rod extends toward the partition wall in response to an increase in temperature, the valve member is moved with the valve rod until the valve rod is in a predetermined position. controlling the flow rate between the valve member and the partition wall,
An intake air amount control valve for an internal combustion engine, characterized in that the valve rod further extends by a predetermined amount to control the flow rate between the valve member and the groove.
