Abstract:
1. A suction muffler for compressors, comprising: a refrigerant channel communicating at an inlet thereof with a suction pipe which guides a refrigerant to a compressor, and communicating at an outlet thereof with a compression chamber in which the refrigerant is compressed; and an outer casing having a structure to convert a flowing motion of the refrigerant into a spiral flowing motion while the refrigerant flows from the suction pipe to the inlet, wherein the outer casing having the structure to convert the flowing motion of the refrigerant into the spiral flowing motion surrounds a sidewall of the channel, with a refrigerant flowing space having a “U”-shaped longitudinal cross-section defined between the sidewall of the channel and the outer casing, thus guiding the refrigerant from the suction pipe to around the sidewall of the channel.
