摘要： A compressor may include a shell, a compression mechanism, a bearing housing, a shroud, a stator, and a rotor. The compression mechanism includes a scroll member that is attached to the shell. The shroud is rotatably fixed relative to the shell and attached to the bearing housing. The stator is fixed relative to the shell. The shroud may have an annular body including an inner surface defining a center shroud passage. The stator may have an outer surface defining a stator passage. An outer surface of the rotor and an inner surface of the stator may be spaced apart and define a discharge gap in fluid communication with the center shroud passage and the stator passage. A continuous passage may extend between a top surface of the scroll member and a bottom surface of the shroud and may be in fluid communication with the shroud passage.

摘要： A compressor may include a first scroll member, a second scroll member and a drive shaft. The first scroll member may include a first end plate defining a first discharge port and a first spiral wrap extending from the first end plate. The second scroll member may include a second end plate defining a first variable volume ratio port and a second spiral wrap extending from the second end plate and meshingly engaged with the first spiral wrap and forming compression pockets. The variable volume ratio port may be located radially outward relative to the first discharge port and in communication with a first compression pocket. The drive shaft may be engaged with the second scroll member and driving orbital displacement of the second scroll member relative to the first scroll member.

摘要： 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.

摘要： 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.

摘要： A compressor includes a non-orbiting scroll, an orbiting scroll, a driveshaft, a bearing housing and a bushing. The non-orbiting scroll includes a first spiral wrap. The orbiting scroll includes an end plate having a first side and a second side. The first side has a second spiral wrap that extends therefrom and meshingly engages with the first spiral wrap of the non-orbiting scroll. The second side has a hub extending therefrom. The driveshaft has a crankpin that is received in the hub and that drives the orbiting scroll. The bushing includes a first member and a second member. The first member is disposed within the hub of the orbiting scroll between the hub and the crankpin of the driveshaft. The second member extends radially from the first member and is disposed between the hub and the bearing housing.

摘要： 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.

摘要： A compressor is provided and may include a shell, a main bearing housing disposed within the shell, a driveshaft, a non-orbiting scroll member, and an orbiting scroll member. The driveshaft may be supported by the main bearing housing. The non-orbiting scroll member may be coupled to the main bearing housing and may include a first lubricant supply path in fluid communication with a lubricant source. The orbiting scroll member may be rotatably coupled to the driveshaft and may be meshingly engaged with the non-orbiting scroll member. The orbiting scroll member may include a recess that is moved between a first position in fluid communication with the first lubricant supply path and a second position fluidly isolated from the first lubricant supply path.
