The first negative pressure chamber is divided into a negative pressure chamber and a second negative pressure chamber.
The anti-afterburn valve opens and closes the air supply passage that supplies air downstream of the throttle valve by means of a valve fixed to the diaphragm when intake pipe negative pressure is introduced into the negative pressure chamber of the anti-afterburn valve. A slider housing an expansion/contraction body whose volume changes depending on the temperature is disposed in the upper part of the second negative pressure chamber of the valve, and engine cooling water is heated to flow into the outer casing of the expansion/contraction body. An anti-afterburn valve characterized in that a means is provided.
