Claim 10:
11. A method for compressing a refrigerant, the method being performed by a compressor, comprising:
receiving a refrigerant at a suction port of the compressor;
compressing the refrigerant in at least one compression chamber, which is 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 formed by the means for compressing and supplying the extracted portion of the refrigerant to a motor of the compressor,
wherein the compressor further comprises:
a low pressure side and a high pressure side, wherein the discharge port is arranged at the high pressure side of the compressor and the suction port and the motor are arranged at the low pressure side, and wherein a transition area between the low pressure side and the high pressure side is formed by the means for compressing; and
at least one tube, wherein the tube is in fluid communication with the opening and ends in the low pressure side below the motor, thereby being configured for piping the extracted portion of the refrigerant from the at least one compression chamber to the low pressure side and for distributing the extracted portion of the refrigerant in a proximity to the motor.
