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