Abstract
A sealed compressor assembly includes a compressor pump driven by a motor mounted within a sealed housing. The sealed housing comprises a center shell extending between first and second ends and a lower shell attached to the center shell. The lower shell is generally square shaped with mounting feet extending diagonally from each corner. The lower shell includes a predetermined amount of material removed to shift the resonance frequency of the sealed housing outside the operating frequency range of the motor and compressor.
Claims18
A sealed compressor assembly comprising:
- a compressor pump unit and a motor mounted within a sealed housing;
- said sealed housing comprising a first shell section;
- and
- a second shell section attached to said first shell section said second shell section including a top surface and at least one skirt extending downward from said top surface, said skirt comprising a width and a cutout disposed within said width for attenuating vibrations and noise within an operating frequency range of said compressor assembly.
A sealed compressor assembly comprising:
- a compressor pump unit and a motor mounted within a sealed housing;
- said sealed housing comprising a first shell section;
- and
- a second shell section formed of sheet material of a thickness, and attached to said first shell section including a top surface and a skirt extending downwardly from said top surface for a width no more than four times said thickness of said second shell.
A sealed compressor assembly comprising:
- a compressor pump unit and a motor mounted within a sealed housing;
- said sealed housing comprising a first shell section;
- and
- a second shell attached to said first shell section and including at least one slot for attenuating vibrations and noise within an operating frequency range of said compressor assembly.
A sealed compressor assembly comprising:
- a compressor pump unit and a motor mounted within a sealed housing, said sealed housing comprising a first shell section;
- and
- a second shell comprising a top surface, a skirt disposed at an angle extending downwardly from said top surface, and a cutout disposed within said skirt.
