This is an air flow control valve that controls the air flow rate in relation to the temperature rise of the engine, and the valve spring 7 moves away from the valve seat 6a.
a valve body 8 which is energized by; a thermally responsive actuator 10 having an operating rod 9 that moves forward and backward as the temperature of the engine changes; a driven member 11 that is driven in the direction; when the valve body 8 is disposed between the valve body 8 and the driven member 11 and the valve body 8 is not in contact with the valve seat 6a, the valve body 8 and the driven member 11
The valve body 8 is connected to the valve seat 6 while maintaining a constant distance between the valve body 8 and the valve seat 6.
A telescopic distance spring 12 is provided for the forward and backward movement of the operating rod 9 while in contact with the
A columnar extension portion 8 is provided on the valve body 8 by passing through the valve port 6b of the valve seat body 6 in which the valve seat 6a is formed.
a, and a guide surface 6c for slidably guiding the extension portion 8a is arranged concentrically with the valve port 6b in the valve seat body 6.
A flow rate control valve for auxiliary air for warm-up operation, characterized in that a flow path 6d for auxiliary air for warm-up operation is opened in the inner peripheral surface of the valve port 6b.
