Claims

[Scope of utility model registration request]

A discharge port communicating between the compression chamber and the discharge chamber is opened in a partition wall interposed between the compression chamber and the discharge chamber, and a base of a discharge valve is fixed to the partition wall facing the discharge chamber side. In the compressor, the tip portion of which is brought into contact with the opening of the discharge port so as to be openable and closable, a flow path for compressed gas passing near the base of the discharge valve is formed in the portion of the partition wall that faces the discharge valve. An opening/closing mechanism for a discharge valve in a compressor.
