Hermetic compressor with one-quarter wavelength tuner

A hermetic compressor for use with a compressible vapor, said compressor comprising:

• a housing having a wall defining an interior plenum;
• a fluid port defining a passageway through said wall and in communication with said interior plenum;
• a motor disposed within said housing;
• a compression mechanism disposed within said housing and operably connected to said motor;
• and
• a tuner comprising a discrete member having an open end and an opposite closed end, said tuner defining a resonating cavity extending from said open end to said closed end, said resonating cavity in direct communication with said interior plenum via said open end, and said open end in indirect communication with said fluid port via said interior plenum.

A method of attenuating the noise and vibration within a hermetic compressor having a housing defining an interior plenum, a motor disposed within the housing, a compression mechanism disposed within the housing, a compressible vapor received within the interior plenum, and a fluid port defining a passageway through the housing and in communication with the interior plenum, said method comprising the steps of:

• providing a tuner defining a resonating cavity and having an open end and an opposite closed end, the resonating cavity defining a length between the open and closed ends;
• positioning the tuner such that the open end is in direct communication with the interior plenum and is in indirect communication with the fluid port via the interior plenum;
• and
• manually adjusting the length of the resonating cavity in response to at least one operating parameter of the compressor.
