Claims

[Scope of utility model registration request]

A low-pressure side check valve is provided in the suction path of the compression element, and opens and closes in response to the rotational movement of the shaft between the first discharge valve of the compression element and the discharge pipe, and closes when the compressor is stopped. A second discharge valve device is disposed avoiding the cylinder, and the second discharge valve device is arranged so as to avoid the cylinder.
The discharge valve device is a rotary compressor that includes a slider that reciprocates according to the rotation of the shaft, and a valve and a valve seat that open and close according to the reciprocating movement.
