    Abstract: A system may include a compressor, a heat exchanger, an expansion device, and first and second working fluid flow paths. The compressor may include a compression mechanism and a motor. The heat exchanger may receive compressed working fluid from the compressor. The expansion device may be disposed downstream of the heat exchanger. The first working fluid flow path may fluidly connect the heat exchanger and the expansion device. The second working fluid flow path may be disposed downstream of the heat exchanger and may fluidly connect the heat exchanger with the compressor. The second working fluid flow path may provide compressed working fluid to the compression mechanism and to the motor.

    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 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 orbiting and non-orbiting scrolls forming first and second fluid pockets therebetween. First and second ports are disposed in the non-orbiting scroll and radially spaced apart from each other. The first port communicates with the first pocket at a first radial position and the second port communicates with the second pocket at a second radial position. A blocking device is movable between a first position preventing communication between the ports and a fluid source and a second position allowing communication between the ports and the fluid source. The first and second pockets have first and second pressures, respectively. One of the pressures may have a disproportionate pressure change compared to the other of the pressures after at least one of the pockets communicates with the fluid source through at least one of the ports. The disproportionate pressure change biases the orbiting scroll relative to the non-orbiting scroll.

    Abstract translation: 压缩机包括在其间形成第一和第二流体袋的轨道和非轨道运动的涡卷。 第一和第二端口设置在非绕动涡旋件中并且彼此径向间隔开。 第一端口在第一径向位置处与第一凹部连通，并且第二端口在第二径向位置处与第二凹口连通。 阻挡装置可以在防止端口和流体源之间的连通的第一位置和允许端口和流体源之间的连通的第二位置之间移动。 第一和第二口袋分别具有第一和第二压力。 在至少一个口袋中的至少一个通过至少一个端口与流体源连通之后，其中一个压力可能与其他压力相比具有不成比例的压力变化。 不成比例的压力变化使轨道涡旋相对于非轨道运动的涡旋偏压。
