    Abstract: 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.

    Abstract translation: 涡旋压缩机包括设置在压缩机壳体内的绕动涡旋件。 绕动涡旋件具有基本上圆形的基板和从其基部延伸的大致螺旋形的卷边。 第一密封件设置在绕动涡旋基板的外周边附近，以在基板和壳体之间提供外部密封。 第二密封件从第一密封件径向向内设置以在基板和壳体之间提供内部密封。 内部密封件和外部密封件之间的空间限定了平衡活塞室。 平衡活塞室通过高压或中压油源加压，以减少基板上的轴向压力差导致的基板上的推力负荷。

    Abstract: A heat transfer circuit that includes a compressor with a gas bearing, a condenser, an expander, an evaporator, a lubricant stream, and a heat source. The lubricant stream receives a portion of the working fluid and supplies the portion of the working fluid to the gas bearing of the compressor. A method of supplying lubricant to a gas bearing of a compressor in a heat transfer circuit includes compressing and further heating at least a portion of the working fluid heated in the evaporator, and supplying the compressed and further heated working fluid to the gas bearing of the compressor. A method of the supplying lubricant to a gas bearing of a compressor in a heat circuit includes generating compressed gaseous working fluid within a lubricant stream.

    Abstract: A variable orifice flow device controls the flow of refrigerant into a compressor motor housing in a compressor. The variable orifice flow device may include, for example, an electronic expansion valve, a thermal expansion valve, or a shuttling valve controlling the flow of refrigerant into a compressor motor housing. One or more flows of refrigerant may be through a fixed orifice, a valve seat of the variable orifice flow device, or leakage through a seal of the compressor motor housing, providing a baseline refrigerant flow to the inside of the compressor motor housing in addition to the flow through the variable orifice flow device.
