    • 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.
    • 本发明提供了一种压缩机,其能够以廉价的结构确保以低流量时的吸入阀的自身引起的振动而减少振动和噪音的发生。 在根据本发明的压缩机中,通过可弹性变形的螺旋构件41形成设置在制冷剂吸入通道13c中的气缸11a的开口调节阀40,螺旋构件41的螺旋部分41a的间隔改变 根据制冷剂的流量,调节通道13c的开口。 因此,可以确保在低流量时减少由于吸入阀14c的自身引起的振动引起的振动和噪声的发生,并且可以简化打开调节阀40的结构。
