    Abstract: A bearing housing drain in a scroll compressor and method for controlling lubrication of a thrust bearing in the scroll compressor are disclosed. The compressor includes a compressor housing; a non-orbiting scroll member and an orbiting scroll member; an orbiting scroll hub having an upper end and a lower end, the lower end being disposed at a vertical elevation that is lower than the upper end; a thrust bearing; a lubricant sump; a housing drain cavity disposed within the compressor housing and configured to receive lubricant from the lubricant sump and to deliver the lubricant to the thrust bearing; and a bearing housing drain fluidly connected to the housing drain cavity and the lubricant sump.

    Abstract: A scroll compressor includes a compressor housing, an orbiting scroll member and non-orbiting scroll member intermeshed to form a compression chamber, a discharge pressure chamber, an intermediate pressure chamber. The housing includes a lower portion, a first intermediate cap, a second intermediate cap, and an upper portion. The discharge pressure chamber configured to receiving a discharge pressure fluid from the compression chamber. The intermediate pressure chamber fluidly connecting an intermediate pressure fluid inlet port and an intermediate pressure fluid injection port of the non-orbiting scroll member. A method injecting an intermediate pressure fluid into a compression chamber of a scroll compressor includes disposing the intermediate pressure fluid in an intermediate pressure chamber. The method also includes injecting the intermediate pressure fluid in the intermediate pressure chamber through the intermediate pressure fluid injection port into the compression chamber.

    Abstract: A scroll compressor is disclosed. The scroll compressor includes a compressor housing; an orbiting scroll member disposed within the housing; a non-orbiting scroll member disposed within the housing, wherein the orbiting scroll member and the non-orbiting scroll member are intermeshed thereby forming a compression chamber within the housing; and an endplate secured to the non-orbiting scroll member. The endplate includes a check valve surface configured to provide a stop for a check valve of the scroll compressor, a radial sealing surface configured to receive a radial seal, an unloading mechanism surface configured to provide a stop for an unloading mechanism, and a pressure chamber for controlling the unloading mechanism, the endplate also including an aperture that fluidly connects the compression chamber and a discharge chamber of the scroll compressor.

    Abstract: A scroll compressor includes a compressor housing containing an orbiting scroll member, a non-orbiting scroll member, bands disposed between the non-orbiting scroll member and the compressor housing, a suction chamber, a discharge chamber, and one or more intermediate injection chamber defined by the bands. The non-orbiting scroll member includes one or more intermediate injection ports fluidly connecting the one or more intermediate injection chambers to at least one compression pocket formed by the intermeshed scroll members. A heating, ventilation, air conditioning, and refrigeration system includes a refrigerant circuit with a condenser, an expander, an evaporator, and the scroll compressor fluidly connected. A method of making a scroll compressor includes placing an upper portion of a compressor housing over a non-orbiting scroll member with bands disposed therebetween, and interference fitting the upper portion onto the non-orbiting scroll member via the bands.

    Abstract: A scroll compressor includes a compressor housing containing an orbiting scroll member, a non-orbiting scroll member, a pair of bands disposed between the non-orbiting scroll member and the compressor housing, a suction chamber, a discharge chamber, and an intermediate injection chamber defined by the pair of bands. The non-orbiting scroll member includes an intermediate injection port fluidly connecting the intermediate injection chamber to at least one compression pocket formed by the intermeshed scroll members. A heating, ventilation, air conditioning, and refrigeration system including a refrigerant circuit with a condenser, at least one expander, an evaporator, and the scroll compressor fluidly connected. A method of making a scroll compressor includes placing an upper portion of a compressor housing over a non-orbiting scroll member with bands disposed therebetween, and interference fitting the upper portion onto the non-orbiting scroll member via the bands.
