A compressor is provided to reflect drawing effect at the time of a low flow rate by a suction drawing valve even when the suction drawing valve does not use the pressure of a crank chamber, and prevent the generation of drawing effect at the time of a high flow rate by the suction drawing valve. A compressor includes elastic supporting elements for elastically supporting a valve element(48) in a valve hole(47) closing direction, wherein the elastic supporting elements are disc springs(55). The disc spring has an area in which a load increase rate required for torsion decreases with respect to the increase of a torsion amount of the disc spring. The valve element has a displacement range including an area in which the load increase rate required for torsion decreases with respect to the increase of the torsion amount of the disc spring.
