Claims

[Scope of utility model registration request]

A piston that moves forward and backward toward a valve hole formed in the case is inserted into a valve chamber formed inside the case, and the piston is urged toward the valve hole by the elastic force of a spring contracted behind the piston. In a normally closed valve, one end of a bellows is fixed to the case and the other end of the bellows is airtightly fixed to the back of the piston, and the valve hole and the bellows are connected to the piston. A valve characterized by having a communication hole for communicating with an internal space.
