Abstract: A compressor may include first and second compression members, first and second bearing assemblies, a sensor, and processing circuitry. The second compression member cooperates with the first compression member to define a compression pocket. The first and second bearing assemblies rotatably support the first and second compression members, respectively. The first bearing assembly may include a bearing rotor and a bearing stator. The bearing stator may surround the bearing rotor and may include poles each having a winding. The sensor may measure a radial position of the bearing rotor relative to the bearing stator. The processing circuitry may be in communication with the sensor and may control electrical current supplied to the windings based on the radial position measured by the sensor to adjust the radial position of the bearing rotor relative to the bearing stator.

Abstract: A compressor may include first and second scrolls, and an axial biasing chamber. Spiral wraps of the scrolls mesh with each other and form compression pockets including a suction-pressure compression pocket, a discharge-pressure compression pocket, and intermediate-pressure compression pockets. The axial biasing chamber may be disposed axially between the second end plate and a component. Working fluid disposed within the axial biasing chamber may axially bias the second scroll toward the first scroll. The second end plate includes outer and inner ports. The outer port is disposed radially outward relative to the inner port. The outer port may be open to a first one of the intermediate-pressure compression pockets and in selective fluid communication with the axial biasing chamber. The inner port may be open to a second one of the intermediate-pressure compression pockets and in selective fluid communication with the axial biasing chamber.

Abstract: A compressor may include a shell, first and second compression mechanisms, first and second motor assemblies, first and second suction inlet fittings, and first and second discharge outlet fittings. The first and second compression mechanisms are disposed within the shell. The first and second motor assemblies are disposed within the shell and drive the first and second compression mechanisms, respectively. The first and second motor assemblies are operable independently of each other. The first suction inlet fitting may be attached to the shell and provides fluid to the first compression mechanism. The first discharge outlet fitting may be attached to the shell and receives fluid compressed by the first compression mechanism. The second suction inlet fitting may be attached to the shell and provides fluid to the second compression mechanism. The second discharge outlet fitting may be attached to the shell and receives fluid compressed by the second compression mechanism.

Abstract: A compressor may include a first compression member, a second compression member, and a motor assembly. The second compression member is movable relative to the first compression member and cooperates with the first compression member to define a compression pocket therebetween. The motor assembly drives one of the first and second compression members relative to the other one of the first and second compression members. The motor assembly includes a stator and a rotor. The rotor is rotatable relative to the stator about a rotational axis. The stator surrounds the rotational axis. The rotor may include magnets that are arranged around the rotational axis. The magnets may be spaced apart from the stator in an axial direction that is parallel to the first rotational axis.

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 may include a shell, first and second scrolls, a seal assembly, a modulation control chamber, and a modulation control valve. The first scroll may include a first end plate having a biasing passage extending therethrough. The seal assembly may isolate a discharge pressure region from a suction pressure region. The seal assembly and the first scroll may define an axial biasing chamber therebetween that communicates with the axial biasing chamber and a first pocket between the first and second scrolls. The modulation control chamber may be fluidly coupled with the biasing chamber by a first passage. The modulation control valve may be fluidly coupled with the modulation control chamber by a second passage and movable between a first position allowing communication between the second passage and the suction pressure region and a second position restricting communication between the second passage and the suction pressure region.

Abstract: A compressor may include first and second scrolls, a hub plate and a valve. The first scroll may include an end plate defining first and second sides, a primary discharge passage extending therethrough, and a secondary discharge passage extending therethrough and located radially outward from the primary discharge passage. The hub plate may be mounted to the first scroll and may include first and second opposite sides and a hub discharge passage in fluid communication with the primary discharge passage. The first side of the hub plate may face the second side of the end plate and may include a valve guide extending axially toward the end plate adjacent the hub discharge passage. The valve member may be secured on the valve guide for axial movement between open and closed positions to respectively allow and restrict fluid communication between the secondary discharge passage and the hub discharge passage.
