摘要： A compressor may include a shell assembly, a non-orbiting scroll, and an orbiting scroll. The shell assembly may define a discharge chamber. The non-orbiting scroll includes a first end plate and a first spiral wrap extending from the first end plate. The first end plate may include a variable-volume-ratio port. The orbiting scroll may be disposed within the discharge chamber. The orbiting scroll includes a second end plate and a second spiral wrap extending from the second end plate and cooperating with the first spiral wrap to define a plurality of fluid pockets therebetween. The second end plate may include a discharge passage in communication with a radially innermost one of the fluid pockets and the discharge chamber. The variable-volume-ratio port may be disposed radially outward relative to the discharge passage and may be in selective communication with the radially innermost one of the fluid pockets.

摘要： 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.

摘要： A compressor may include a shell, first and second scroll members, a partition plate and a bypass valve member. The shell defines a discharge-pressure region and a suction-pressure region. The first scroll member is disposed within the shell and may include a first end plate having a discharge passage, and first and second bypass passages extending through the first end plate. The partition plate is disposed within the shell and separates the discharge-pressure region from the suction-pressure region and includes an opening in communication with the discharge-pressure region. The bypass valve member is movable between a first position restricting fluid flow through at least one of the first and second bypass passages and the opening and a second position in allowing fluid flow through the at least one of the first and second bypass passages and the opening.

摘要： A scroll compressor includes a fixed scroll; an orbiting scroll that interfaces the fixed scroll; an Oldham ring that interfaces the orbiting scroll and has a pre-unbalanced force profile; and a motor shaft that interfaces the Oldham ring. The Oldham ring pre-unbalanced force profile is in the form of a sine wave. One of the shaft and the orbiting scroll has an imbalance weight portion; wherein the imbalance weight portion provides a weighted force profile that is 180° opposite of the pre-unbalanced force profile of the Oldham ring and produces in the Oldham ring a post-unbalanced force profile that is substantially a flat line.

摘要： A scroll compressor with unfastened thrust plate includes a compressor housing and scroll compressor bodies disposed in the compressor housing. The scroll bodies include a fixed scroll body and a moveable scroll body. The fixed and moveable scroll bodies have respective bases and respective scroll ribs that project from the respective bases. The scroll ribs mutually engage. The moveable scroll body is movable relative to the fixed scroll body for compressing fluid. An upper bearing member provides axial thrust support to the moveable scroll compressor body through a bearing support via an unfastened thrust plate that is located between the upper bearing member and the moveable scroll body. The unfastened thrust plate has no means of attachment to the upper bearing member or to the moveable scroll body.
