The invention provides a compressor that can reduce occurrence of vibration and noise due to self-induced vibration of an suction valve at the time of a low flow rate surely with an inexpensive structure. In the compressor according to the invention, an opening regulating valve 40 provided in a refrigerant suction channel 13 c to a cylinder 11 a is formed by an elastically deformable spiral member 41 , and intervals of spiral portions 41 a of the spiral member 41 are changed according to a flow rate of a refrigerant, whereby an opening of the channel 13 c is regulated. Thus, it is possible to reduce occurrence of vibration and noise due to self-induced vibration of an suction valve 14 c at the time of a low flow rate surely, and it is possible to simplify a structure of the opening regulating valve 40.
