ABSTRACT:
The suction muffler for a hermetic reciprocating compressor having a reciprocating compressing portion, comprises a muffler body formed with a space for containing a refrigerant and having a refrigerant inlet for receiving the refrigerant and a connection portion for transferring the refrigerant to the compressing portion. A wall partitions the refrigerant containing space into a first containing portion which is connected to the refrigerant inlet and a second containing portion which is connected to the connection portion. The partitioning wall is formed with a hole for communicating the first containing portion with the second containing portion. A tubular baffle extends from the connection portion to the inside of the containing space. Accordingly, various paths having various resonance lengths are provided, thereby damping noises having various frequency components effectively.
