  • Patent number: 10436201
    Abstract: A scroll compressor includes a scroll compression unit having a fixed scroll and an orbiting scroll a drive shaft configured to drive the orbiting scroll in an orbital movement, and a support frame including a bearing configured to guide in rotation a guided portion of the drive shaft. The scroll compressor also includes an anti-rotation device including a pair of first engaging elements slidably engaged with a pair of complementary engaging elements on the support frame; and a lubrication system to lubricate at least partially the first engaging elements. The lubrication system includes a lubrication channel and hole on the drive shaft; the hole is fluidly connected to the channel and emerges in an outer wall of the guided portion. The system further includes an oil lubrication passage on the support frame, which includes an oil inlet aperture emerging in a receiving chamber, and an oil outlet aperture configured to supply with oil at least one of the first engaging elements.

  • Patent number: 7273363
    Abstract: A slider block for a scroll compressor has a recess formed in a wall between a flat portion on the outer surface and a chamfer formed on the inner surface. The recess eliminates a high stress area of the prior art, and reduces cracks originating from this area of the slider block.

  • Publication number: 20070009371
    Abstract: A scroll compressor assembly includes a shaft having an eccentric pin that orbits a first scroll member relative to a second scroll member. The eccentric pin has a length extending from a base end to a distal end, which defines a contact area having a slight crown that engages a slider block. The contact area is moved toward the distal end of the eccentric pin to improve the stability of at least one of the first and second scroll members.

  • Patent number: 6648616
    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.
