Abstract

A compressor according to the present invention can reduce a flow resistance of refrigerant gas by providing a communicating tube outlet of a suction muffler with a protrusion that protrudes toward a direction to which the refrigerant gas flows rather than a direction of a suction hole (111) in a valve plate (112), and by providing the facing valve plate (112) with a inhalation pathway (132). This increases a suction mass of refrigerant per unit time (refrigerant circulation volume) and workload per unit time, and thus it is possible to realize a compressor with high efficiency.
