Abstract: A compressor may include a shell, first and second scroll members, and a seal assembly. The shell defines a first and second pressure regions. The first scroll member may include a first end plate defining a chamber. The seal assembly may surround the discharge passage and fluidly separate the first and second pressure regions from each other. The seal assembly may include first and second sealing members. The first sealing member may prevent communication between the chamber and the second pressure region when a first fluid pressure within the second pressure region is higher than a second fluid pressure within the chamber. The first sealing member may define a leakage path when the first fluid pressure is lower than the second fluid pressure. The second sealing member may fluidly separate the chamber and the second pressure region when the first fluid pressure is lower than the second fluid pressure.
Abstract translation: 压缩机可以包括壳体，第一和第二涡旋构件以及密封组件。 壳体限定第一和第二压力区域。 第一涡旋构件可以包括限定腔室的第一端板。 密封组件可以围绕排放通道并且将第一和第二压力区域彼此流体地分离。 密封组件可以包括第一和第二密封构件。 当第二压力区域内的第一流体压力高于室内的第二流体压力时，第一密封构件可以防止腔室和第二压力区域之间的连通。 当第一流体压力低于第二流体压力时，第一密封构件可以限定泄漏路径。 当第一流体压力低于第二流体压力时，第二密封构件可以流体地分离腔室和第二压力区域。

Abstract: A compressor includes first and second scroll members (76; 78), first and second bearing housings (14;16), and a motor assembly (20). The first scroll member (76) includes a first end plate (80) and a first spiral wrap (82) extending from the first end plate (80). The second scroll member (78) includes a second end plate (86) and a second spiral wrap (88) extending from the second end plate (86) and intermeshed with the first spiral wrap (82) to define compression pockets (122) therebetween. The first bearing housing (14) supports the first scroll member (76) for rotation about a first rotational axis (A1). The second bearing housing (16) supports the second scroll member (78) for rotation about a second rotational axis (A2) that is parallel to and offset from the first rotational axis (A1). The motor assembly (20) is disposed axially between the first and second bearing housings (14;16) and includes a rotor (100) attached to the first scroll member (76). The rotor (100) surrounds the first and second end plates (80;86).

Abstract: A compressor hub assembly may include a hub member, a valve retainer and a valve member. The hub member may include first and second portions. The first portion may define an annular hub wall for a compressor and may have a first inner diameter. The second portion may have a second inner diameter greater than the first inner diameter and may define a stepped region between the first and second portions. The valve retainer may be fixed to the hub member at an end of the second portion opposite the stepped region and may define a third inner diameter. The valve member may be located between the valve retainer in the stepped region and may have an outer diameter less than the second inner diameter and greater than the first and third inner diameters.

Abstract: A compressor may include a shell assembly defining suction and discharge pressure regions, first and second scroll members disposed within the shell assembly, and a capacity modulation assembly. The first scroll member may include a first end plate defining a discharge passage, a biasing passage, a modulation port, a first spiral wrap extending from a first side of the first end plate, and an annular hub extending from a second side of the first end plate. The second scroll member may include a second spiral wrap meshingly engaged with the first spiral wrap forming a suction pocket in communication with the suction pressure region, intermediate compression pockets, and a discharge pocket in communication with the discharge passage. A first intermediate compression pocket may be in communication with the biasing passage and a second intermediate compression pocket may be in communication with the modulation port.

Abstract: A compressor may include a shell assembly, a compression mechanism and a conduit. The shell assembly may include a fitting through which fluid is received from outside of the compressor. The compression mechanism may be disposed within a chamber defined by the shell assembly. The conduit may extend through the chamber between the fitting and a suction inlet of the compression mechanism and transmit at least a portion of the fluid from the fitting to the suction inlet. The conduit may include an inlet that may be spaced apart from the fitting and an outlet that may engage the compression mechanism.

Abstract: A compressor comprising:
a first scroll member having a first end plate (1080) and a first spiral wrap (1082) extending from the first end plate;
a second scroll member having a second end plate (1086) and a second spiral wrap (1088) extending from the second end plate and intermeshed with the first spiral wrap to define compression pockets therebetween;
a first bearing housing (1014) supporting the first scroll member for rotation about a first rotational axis (A1);
a second bearing housing (1016) supporting the second scroll member for rotation about a second rotational axis (A2) that is offset from the first rotational axis (A1); and
a motor assembly (1020) engaging one of the first and second scroll members and driving rotation of the first and second scroll members about the first and second rotational axes, respectively,
wherein the first bearing housing (1014) includes a radially extending suction passage (1102) providing fluid communication between a suction inlet (1028) of a shell of the compressor and a suction inlet opening (1094) in the first end plate (1080), and
wherein working fluid exits the radially extending suction passage (1102) at a location (1106) that is disposed radially inward relative to the suction inlet opening (1094) such that windage produced by rotation of the first scroll member aids in forcing the working fluid radially outward toward the suction inlet opening (1094).-

Abstract: A compressor includes a shell (12), first (18) and second (25) compression mechanisms, first (20) and second (27) motor assemblies, first (34) and second (46) suction inlet fittings attached to the shell, and first (38) and second (50) discharge outlet fittings attached to the shell. The first and second compression mechanisms (18;25) are disposed within the shell. The first and second motor assemblies (20;27) are disposed within the shell, drive the first and second compression mechanisms (18;25), respectively, and are operable independently of each other. The first suction inlet fitting (34) provides fluid to the first compression mechanism (18). The first discharge outlet fitting (38) receives fluid compressed by the first compression mechanism (18). The second suction inlet fitting (46) provides fluid to the second compression mechanism (25). The second discharge outlet fitting (50) receives fluid compressed by the second compression mechanism (25).
