Abstract
A baffle member for use in scroll compressors. In one exemplary embodiment, the baffle member is attached to a portion of the crankcase and, in use, deflects lubricant that may be thrown from the thrust surface of the crankcase during operation of the compressor away from the flow of working fluid, and also aids in directing the flow of working fluid away from the thrust surface of the crankcase and toward a suction inlet in the compression mechanism.
Claims16
A vertical scroll compressor defining perpendicular axial and radial directions, comprising:
- a housing having a suction port;
- a compression mechanism disposed within said housing and including a non-orbiting scroll having a first involute wrap and an orbiting scroll having a second involute wrap;
- a motor drivingly connected to said orbiting scroll;
- a crankcase including a thrust surface disposed at an axial thrust surface height, said thrust surface having a plurality of lubricant retaining recesses formed therein and said orbiting scroll bearingly supported on said thrust surface;
- and
- a baffle member removably positioned on said crankcase and disposed radially between said thrust surface and said suction port, said baffle member having a body portion with an upper surface disposed at an axial baffle member height, said baffle member height being greater than said thrust surface height, whereby said baffle member extends above said thrust surface of said crankcase.

- a compression mechanism disposed within said housing and including a non-orbiting scroll having a first involute wrap and a suction inlet, and an orbiting scroll having a second involute wrap;
- a motor drivingly connected to said orbiting scroll;
- a crankcase including a thrust surface disposed at an axial thrust surface height, said orbiting scroll bearingly supported on said thrust surface;
- and
- a baffle member removably positioned on said crankcase and disposed radially between said thrust surface and said suction port, said baffle member having a body portion including an inclined surface disposed at least partially axially above said crankcase, said inclined surface facing a flow path of working fluid from said suction port to said suction inlet.
