  • Compressor having a helmholtz type resonance chamber with a lowermost end connected to a gas passage
    Patent number: 7704059
    Abstract: A compressor includes a first muffler chamber communicating with a first cylinder chamber, and a second muffler chamber communicating with a second cylinder chamber. The first muffler chamber and the second muffler chamber are communicated with each other by a gas passage. The gas passage is communicated with a Helmholtz type resonance chamber by a connecting passage. The connecting passage is connected to a lowermost end of the resonance chamber. Therefore, oil contained in the refrigerant gas, even if having entered into the resonance chamber, is discharged through the connecting passage located at the lowermost end of the resonance chamber to outside of the resonance chamber. Thus, since oil is not accumulated in the resonance chamber, the resonance chamber keeps generally constant in capacity at all times.

  • Rotary compressor with reduced refrigeration gas leaks during compression while preventing seizure
    Patent number: 7556485
    Abstract: A rotary compressor includes a cylinder body, end plate members fitted on both sides of the cylinder body, a roller placed in a cylinder chamber, a blade fitted to the roller, and a bushing for supporting the blade. A width of the bushing in a roller axis direction is larger than an axial width of the roller. A gap in the roller axis direction between the roller and the end plate members is larger than a gap in the roller axis direction between the bushing and the end plate members.
