Abstract
A compressor comprises a suction port configured to receive a refrigerant and means for compressing the refrigerant. The means for compressing forms at least one compression chamber, a discharge port configured for discharging the compressed refrigerant from the compressor, and a motor. The means for compressing comprises at least one opening for extracting a portion of the refrigerant from the at least one compression chamber and supplying the extracted portion of the refrigerant to the motor. A method comprises receiving a refrigerant at a suction port of the compressor, compressing the refrigerant in at least one compression chamber formed by a means for compressing of the compressor, discharging the refrigerant from the compressor at a discharge port of the compressor, and extracting a portion of the refrigerant from the at least one compression chamber and supplying the extracted portion of the refrigerant to a motor of the compressor.
