Claims

[Scope of utility model registration request]

A hollow valve body is provided in a valve seat tube fixed to a refrigerant conduit via a sealing member, and a spring-biased valve stem is inserted into this valve body, and the valve stem is moved by the elastic force of the spring. The refrigerant injection valve is configured to open and close an end opening of the valve body by displacing the valve body against the pressure, and the refrigerant injection valve is configured such that the valve stem is supported by the valve body at at least two points. .
