Abstract
A compressor may include a shell, a compression mechanism, a crankshaft, a bearing support, and a lubricant sump. The compression mechanism may be disposed in the shell and may compress a working fluid. The crankshaft may be disposed at least partially in the shell and may drivingly engage the compression mechanism. The bearing support may rotatably support the crankshaft. The lubricant sump may retain a volume of lubricant and may be disposed between the bearing support and the compression mechanism.
Claims20
A compressor comprising:
- a shell;
- a compression mechanism disposed in said shell and compressing a working fluid;
- a crankshaft disposed at least partially in said shell and drivingly engaged with said compression mechanism;
- a bearing support rotatably supporting said crankshaft;
- and
- a lubricant sump for retaining a volume of lubricant and disposed between said bearing support and said compression mechanism,
- wherein said shell defines a first lubricant passageway that is fluidly separated from said lubricant sump and in communication with an inlet of the compressor that is distinct from a working fluid inlet of the compressor.
A compressor comprising:
- a shell defining a suction-pressure region and a discharge-pressure region;
- a compression mechanism disposed between said suction-pressure region and said discharge-pressure region;
- a first lubricant sump disposed in said suction-pressure region;
- a second lubricant sump disposed in said discharge-pressure region;
- a crankshaft drivingly engaging said compression mechanism;
- a bearing support rotatably supporting said crankshaft;
- and
- a thrust plate engaging said compression mechanism and disposed between said compression mechanism and said bearing support, said first lubricant sump being defined by said thrust plate, said bearing support, and said shell,
- wherein said bearing support and said thrust plate both include a plurality of openings allowing said working fluid and said lubricant to flow throughout said shell.
A compressor comprising:
- a shell defining a suction-pressure region and a discharge-pressure region;
- a compression mechanism disposed between said suction-pressure region and said discharge-pressure region;
- a first lubricant sump disposed in said suction-pressure region;
- and
- a second lubricant sump disposed in said discharge-pressure region,
- wherein said shell defines a lubricant passageway that is separated from said first and second lubricant sumps and in communication with an inlet of the compressor that is distinct from a working fluid inlet of the compressor.
