Abstract: 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.

Abstract: A compressor may include a shell, a compression mechanism, a motor, a pumping mechanism, and a heat exchanger. The shell may define an internal cavity and an oil sump. The compression mechanism is disposed the said shell. The motor is coupled to a driveshaft for selectively powering the compression mechanism. The pumping mechanism may be in fluid-pumping communication with the oil sump. The first heat exchanger may be disposed external from the shell and in fluid communication with the pumping mechanism. The first heat exchanger may cool the oil prior to returning the cooled oil to the internal cavity.

Abstract: A compressor may include first and second scroll members having first and second scroll wraps, respectively. The scroll members define a suction inlet, a discharge outlet, and fluid pockets moving therebetween. The second scroll member may include a port, and a passage. The port may be in fluid communication with at least one of the pockets. The passage may extend through a portion of the second end plate and may be in fluid communication with the port. A valve assembly may be disposed in the passage and may include a valve member displaceable between open and closed positions. A recompression volume may be disposed between the valve member and the at least one of the pockets. The recompression volume may be less than or equal to approximately one percent of a volume of one of the pockets at a suction seal-off position.
