A noise reducing device for a hermetic type compressor is provided that includes a plate film in a connection member that connects a suction pipe and a suction muffler to each other. The plate film bends and opens when a refrigerant is sucked while preventing a back flow of noise. The plate film is capable of sucking the refrigerant without interference and preventing noise or pressure pulsation transferred in a direction of the suction pipe in the suction muffler, and thereby is capable of remarkably reducing noise of the compressor.

Noise reducing device for hermetic type compressor

A muffler for a compressor has a chamber between an inlet and an outlet and a communicating pipe for indirectly connecting the inlet to the outlet, whereby a suction loss of a refrigerant sucked into the muffler for the compressor can be reduced and also pressure pulsation can be reduced so as to enhance a cooling capability of the compressor and achieve a noise reduction effect. Also, an assembling structure of the muffler can be simplified, resulting in reduction of fabricating cost and improvement of productivity.

Muffler for compressor

The present invention discloses a suction muffler for a hermetic compressor which reduces noise of refrigerant. A plate film operating as a kind of flow resistance is provided on a refrigerant suction passage in various shapes and specific positions. Therefore, the suction muffler can effectively reduce pressure pulsation transferred to the outside and guarantee flow efficiency, although the refrigerant is directly sucked thereinto.

Suction muffler for hermetic compressor

The present invention relates to a discharging noise system of a hermetic compressor. The present invention includes a first discharging noise suppressor () provided at one side end of a cylinder blockto firstly reduce noise and pulsation of work fluid compressed in and discharged from a compressing chamber () formed to be bored through the cylinder block () in a fore and aft direction, a second discharging noise suppressor (') provided at the other side end of the cylinder block () and communicating with the first discharging noise suppressorto secondarily reduce noise and pulsation of the work fluid with noise and pulsation reduced by the first discharging noise suppressor (), a connection pipe () for allowing the first and second discharging noise suppressors () and (&#x2032;) to communicate with each other to form a channel for allowing the work fluid to move, the connection pipe () having a length longer than a shortest straight distance between the discharging noise suppressors (and&#x2032;), and a discharging pipe () provided at the second discharging noise suppressor (&#x2032;) to form a channel through which the work fluid is discharged to the outside. According to the present invention configured as above, the connection pipe is relatively long to reduce pulsation, thereby improving operating characteristics of the hermetic compressor, so that vibration generated by the pulsation is reduced to improve durability of the hermetic compressor.
