Claims

[Scope of utility model registration request]

During engine warm-up, the flow rate of auxiliary air that bypasses the throttle valve in the main intake passage and flows through the bypass air passage that communicates the upstream and downstream sides of the throttle valve is controlled in relation to the rise in engine temperature. A valve seat body 6 in which a valve seat 6a is formed; a valve body 7 that performs a valve action in cooperation with the valve seat 6a; a valve spring 8 that urges the valve body 7 in a direction to open the valve; a thermally responsive actuator 10 that is provided with an operating rod 9 that moves forward and backward as the temperature of the engine changes; and a driven member 11 that follows the forward and backward movements of the actuating rod 9; which is disposed between the valve body 7 and the driven member 11, and when the valve body 7 is away from the valve seat 6a, the valve A telescopic distance spring is used to maintain a constant distance between the body 7 and the driven member 11, and to move the operating rod 9 back and forth while the valve body 7 is in contact with the valve seat 6a. 12, in which the driven member 11 forms a seat for the valve spring 8 and the distance spring 12;
1a; means for locking the saucer 11a at the end that comes into contact with the actuating rod 9, and having the other end slidably engage with the valve body 7, and for preventing the valve body 7 from falling off; The actuating rod 9 and the valve rod 11b have flanges 9a and 11c formed at their ends that abut each other, so that the large diameter end surfaces of the actuating rod 9 and the valve rod 11b abut against each other. A warm-up operation aid is provided in which a positioning means for keeping the operating rod 9 and the valve rod 11b concentrically is formed on the end face, and the valve spring 8 is disposed between the valve seat body 6 and the saucer 11a. Air flow control valve.
