摘要： A scroll compressor includes an orbiting scroll member disposed within a compressor housing. The orbiting scroll member has a substantially circular baseplate and a generally spiral wrap extending from its base. A first seal is disposed proximal to the outer periphery of the orbiting scroll baseplate to provide an external seal between the baseplate and the housing. A second seal is disposed radially inward from the first seal to provide an internal seal between the baseplate and the housing. A space between the internal seal and the external seal defines a balance piston chamber. The balance piston chamber is pressurized via a high or intermediate pressure oil source to reduce thrust loading on the baseplate caused by an axial pressure differential across the baseplate.

摘要： A heating, ventilation, air conditioning, and refrigeration (HVACR) system is disclosed. The HVACR system includes a refrigerant circuit. The refrigerant circuit includes a compressor, a condenser, an expansion device, and an evaporator fluidly connected. A controller is electronically connected to the compressor. The controller is configured to prevent the compressor from operating at a speed that is less than a minimum speed limit. A lubricant separator has an inlet fluidly connected between the compressor and the condenser and a plurality of outlets. A first of the plurality of outlets is fluidly connected to the condenser. A second of the plurality of outlets is fluidly connected to one or more components of the compressor to provide a lubricant to the one or more components.

摘要： A scroll compressor orbiting scroll bearing lubrication system includes a scroll compressor crankshaft having a lubricating fluid gallery extending therethrough between a first stage orbiting scroll and a second stage orbiting scroll. The first stage employs an orbiting scroll radial bearing and an orbiting scroll hydrodynamic thrust bearing, while the second stage employs an orbiting scroll radial bearing and an orbiting scroll hydrostatic thrust bearing. Lubricating fluid is supplied to the second stage orbiting scroll radial bearing via the lubricating fluid gallery.

摘要： A heating, ventilation, air conditioning, and refrigeration (HVACR) system is disclosed. The HVACR system includes a compressor, a condenser, and an evaporator fluidly connected to form a refrigerant circuit. A lubricant return line is fluidly connected to the compressor and to the evaporator. A pressure difference between the compressor and the evaporator induces a fluid flow of lubricant from the evaporator to the compressor.

摘要： A compressor crankshaft assembly includes a crankshaft and an eccentric drive pin extending from one end of the crankshaft. The shape of the drive pin viewed into the exposed end of the drive pin is defined by the intersection of a first cylinder that is coaxial with the axis of a substantially cylindrical orbital bearing journaled and installed to receive the eccentric drive pin and a second cylinder that is coaxial with the axis of a substantially cylindrical main bearing journaled and installed to rotatably receive the crankshaft, such that the area defined by the intersecting portion is less than the area defined by either cylinder.
