Abstract:
1. A compressor assembly comprising: a housing defining an interior plenum and having an inlet opening; a stationary scroll member fixed within said housing; an orbiting scroll member disposed within said housing and engaged with said stationary scroll member; an oil sump disposed within said interior plenum; a shaft rotatable about a shaft axis, said shaft operably coupled with said orbiting scroll member; a motor operably coupled with said shaft; a crankcase fixed within said housing and disposed between said orbiting scroll member and said motor, said crankcase having a thrust surface engageable with said orbiting scroll member and defining a first opening, said crankcase including a bearing support portion defining a second opening, said shaft freely extending through said first opening and extending through and bearingly supported at said second opening; said crankcase having a shield portion extending from proximate said first opening to proximate said second opening and defining a partial enclosure for said shaft between said first opening and said second opening, said shield portion defining an aperture providing fluid communication between said interior plenum and said partial enclosure, said aperture axially extending from proximate said first opening to proximate said second opening, said shield portion circumferentially extending about said shaft through an arc of at least 180 degrees and spaced radially outwardly of said shaft; a sheet-like baffle member secured to said crankcase and positioned proximate said inlet opening; wherein said crankcase includes a plurality of legs extending from proximate said thrust surface substantially parallel to said shaft axis and having distal ends engageable with said motor; and said baffle member being secured to at least one of said legs.
