The present disclosure relates to a new breed of high performance compressors and associated vapor compression systems that can be used in wide ranging refrigeration, cooling and heating applications with significantly increased compressor isentropic efficiency, motor efficiency, reliability and longevity of the motor, the compressor pump and the system as a whole, as well as COP, heating capacity, and SEER of the new vapor compression systems utilizing the new high performance compressors. The design philosophy and modifications to the current configuration of rolling piston rotary compressor to arrive at the high-performance version of the same type will be readily applicable to other types of vapor compression compressors with only minor changes opening the way for adoption of the new design philosophy by the entire compressor industry resulting in serious reduction of carbon footprint for air conditioners, heat pumps and refrigerators worldwide. 137-. (canceled)38. A compressor comprising:at least one pressure containment shell;a motor and a motor heat exchanger, wherein the motor and the motor heat exchanger are positioned in a pressure containment shell of the at least one pressure containment shell;a pump body positioned in a pressure shell of the at least one pressure containment shell;wherein the pump body includes a pump operatively coupled to the motor;wherein the motor heat exchanger is configured to accept refrigerant diverted from a condenser or a high pressure heat exchanger of a refrigeration system, whereby the motor heat exchanger is configured to cool the motor, to decrease operating temperature of the motor, and to increase electrical efficiency of the motor;a compression chamber within the pump body; andat least one supercharging port or valve provided in the pump body leading into the compression chamber configured to receive the diverted refrigerant, after cooling the motor, such that the diverted refrigerant is injected back into the ...
