Patent ID: 7942642

Claim:
A method for compressing a refrigerant, comprising: inputting a refrigerant into a compressor, wherein the compressor comprises a positive displacement mechanism, wherein the positive displacement mechanism comprises a substantially triangular shape rotor that spins on an eccentric shaft, wherein the rotor rotates inside an epitrochoid chamber, wherein a first volume of refrigerant vapor enters the positive displacement mechanism and is compressed such that a second volume of compressed refrigerant vapor exits the positive displacement mechanism, wherein the second volume is smaller than the first volume, wherein the compressed refrigerant exits the compressor, wherein the epitrochoid chamber comprises a first wall and a second wall, wherein the rotor comprises a first rotor side surface and a second rotor side surface, wherein the rotor rotates parallel to a plane that is parallel to the first rotor side surface and parallel to the second rotor side surface, wherein the lane is parallel to a first surface of the first wall and parallel to a second surface of the second wall, wherein the refrigerant is input into the compressor via an inlet port, wherein as the rotor rotates inside the epitrochoid chamber, the rotor travels over the inlet port so as to close the inlet port and prevent the refrigerant from entering the epitrochoid chamber and the rotor further travels so as to open the inlet port and allow the refrigerant to enter the epitrochoid chamber, wherein the inlet port is positioned on the first wall, wherein the refrigerant exits the compressor through an exhaust port, wherein as the rotor rotates inside the epitrochoid chamber the rotor travels over the exhaust port so as to close the exhaust port and prevent the refrigerant from exiting the epitrochoid chamber and the rotor further travels so as to open the exhaust port and allow the refrigerant to exit the epitrochoid chamber, wherein the exhaust port is positioned on the second wall, wherein the rotor rotates such that the exhaust port is closed when the inlet port is open and the inlet port is closed when the exhaust port is open.
