Claims

[Scope of utility model registration request]

An air suction port, an air discharge port, a valve seat provided at a position between the air suction port and the air discharge port, a valve body that is in contact with and separate from this valve seat and measures circulating air, and this valve body. The solenoid has a shaft that supports the shaft, a solenoid, a stator core that coaxially includes the shaft and that forms part of a magnetic field loop generated by the solenoid, and a return spring that biases the shaft. In the air control valve, the position of the valve body is controlled by the balance between the attraction force of a magnetic field and a return spring, the bellows forming a sealed space at the rear of the valve body; and a ventilation hole communicating with the space on the front side of the valve body, the rear end of the stator core is tilted outward, an adjustment screw is screwed into the rear end, and the tip of the adjustment screw is connected to the rear end of the stator core. An air control valve characterized in that the return spring is placed between the rear end of the shaft.
