To provide a compressor capable of extending the life of a valve element and improving the compression efficiency of the compression chamber by improving the structure of a valve device opening/closing a discharge port where compressed gas is discharged from a compression chamber.
The compressor 1 includes a casing 3, a driving part received in the casing and generating a driving force, and a compression part compressing gas by the driving force of the driving part, which is provided with a suction port sucking gas and a discharge port discharging the compressed gas, and the valve device 40 opening/closing the discharge port. The valve device has a cylindrical inner surface communicated with the discharge port 39, and includes a valve receiving part communicated with a gas discharge passage 35, which is provided to discharge the compressed gas discharged through the discharge port, and the valve element 41 in a bent form, which is received by the valve receiving part to close the discharge port elastically and open it by the compressed gas of the compression part.
