Suction baffle for scroll compressors

A compressor, comprising:

• a housing having a suction port and a discharge port;
• a motor-compressor unit disposed within said housing, including a crankcase and a stator, rotor, and drive shaft assembly, said drive shaft rotatably supported by said crankcase;
• a first scroll member fixed with respect to said housing and defining perpendicular axial and radial directions and having a lower end with respect to said axial direction, said first scroll member comprising:
• a base plate;
• a first wrap extending from said base plate;
• an outer wall having a suction inlet facing substantially in the radial direction;
• and
• a baffle member attached to said fixed scroll and including an open end facing substantially in the axial direction toward said suction port, said baffle member having a lower end which does not extend beyond said lower end of said base plate of said first scroll member;
• and
• a second scroll member coupled to said drive shaft for orbital movement, said second scroll member including a second wrap intermeshed with said first wrap.

A compressor, comprising:

• a housing having a suction port and a discharge port;
• a motor-compressor unit disposed within said housing and operable to receive a working fluid at a suction pressure from said suction port, compress the working fluid, and discharge the working fluid at a discharge pressure through said discharge port, said motor-compressor unit comprising:
• a crankcase including at least one wall directly facing said suction port such that working fluid entering said suction port impinges directly on said crankcase wall;
• a stator, rotor, and drive shaft assembly, said drive shaft rotatably supported by said crankcase;
• a first scroll member fixed with respect to said housing and defining perpendicular axial and radial directions, said first scroll member including a base plate, a first wrap extending from said base plate, and an outer wall having a suction inlet facing substantially in the radial direction;
• a second scroll member coupled to said drive shaft for orbital movement, said second scroll member including a second wrap intermeshed with said first wrap;
• a baffle member attached to said first scroll and including a first end facing substantially in the axial direction toward said suction port and a second end facing substantially in the radial direction toward said suction inlet, whereby at least a portion of the working fluid which enters said suction port and impinges directly on said crankcase wall is directed by said baffle member into said suction inlet.
