空気の流量制御弁。 The flow rate of auxiliary air that bypasses a throttle valve in a main intake passage and flows through a bypass air passage communicating an upstream side and a downstream side of the throttle valve during engine warm-up is controlled in relation to a rise in engine temperature. This is an air flow control valve, and includes a valve seat body 6 on which a valve seat 6a is formed; a valve body 7 that performs a valve action in cooperation with the valve seat 6a; and a valve body 7 that is separated from the valve seat 6a. a valve spring 8 that urges the valve body 7 in the direction of opening the valve;
The operating rod 9 moves forward and backward as the engine temperature changes.
a thermally responsive actuator 10 comprising; a driven member 11 that comes into contact with the actuating rod 9 and follows the forward and backward movement of the actuating rod 9; the valve body 7 and the driven member 11;
and the valve body 7 is disposed between the valve seat 6 and the valve body 7.
When the valve body 7 is not in contact with the valve seat 6a, the distance between the valve body 7 and the driven member 11 is kept constant, and the actuating rod 9 moves forward and backward while the valve body 7 is in contact with the valve seat 6a. In the valve seat body 6, a sealing member 6c made of an elastic material is placed concentrically with the valve seat 6a formed on the valve seat body 6. Or a flow rate control valve for auxiliary air for warm-up operation arranged on either side of the valve body 7.
