A positive displacement rotary compressor is designed for near isothermal compression, high pressure ratios, high revolutions per minute, high efficiency, mixed gas/liquid compression, a low temperature increase, a low outlet temperature, and/or a high outlet pressure. Liquid injectors provide cooling liquid that cools the working fluid and improves the efficiency of the compressor. A gate moves within the compression chamber to either make contact with or be proximate to the rotor as it turns.
1. A positive displacement compressor, comprising: a rotor casing that includes a compression chamber with a first end, a second end, and an inner curved surface;a shaft located axially in the compression chamber;a non-circular rotor mounted for rotation with the shaft relative to the rotor casing,
1. A positive displacement compressor, comprising: a rotor casing that includes a compression chamber with a first end, a second end, and an inner curved surface;a shaft located axially in the compression chamber;a non-circular rotor mounted for rotation with the shaft relative to the rotor casing, the non-circular rotor having a sealing portion, the sealing portion having a curved surface that corresponds with the inner curved surface of the compression chamber, and a non-sealing portion;a gate having a first end and a second end, and being operable to move relative to the rotor casing to locate the first end proximate to the rotor as the rotor rotates. 2. The positive displacement compressor of claim 1, further comprising at least one liquid injection nozzle located to provide injected fluids into the compression chamber, wherein the at least one liquid injection nozzle is configured to provide an atomized liquid spray. 3. The positive displacement compressor of claim 1, further comprising at least one liquid injector positioned to inject liquid into an area within the compression chamber where compression occurs during operation of the compressor. 4. The positive displacement compressor of claim 1, further comprising at least one liquid injector connected with the rotor casing to inject liquids into the compression chamber. 5. The positive displacement compressor of claim 1, wherein: the rotor has a first end and a second end aligned horizontally;the gate is located at the bottom of the compression chamber and is operable to move up and down;an inlet is located on the rotor casing on one side of the gate; andan outlet port is located on the rotor casing on the opposite side of the gate. 6. The positive displacement compressor of claim 1, wherein the compressor is configured to be oriented such that the rotor rotates about a horizontal axis during operation of the compressor. 7. The positive displacement compressor of claim 1, further comprising a gate positioning system operable to locate the first end of the gate proximate to the non-circular rotor as the rotor turns. 8. The positive displacement compressor of claim 7, wherein a portion of the gate positioning system is disposed outside of the compression chamber. 9. The positive displacement compressor of claim 7, wherein the gate positioning system comprises at least one cam that drives the gate positioning system. 10. The positive displacement compressor of claim 9, wherein the cam is disposed outside of the compression chamber. 11. The positive displacement compressor of claim 9, wherein the gate positioning system comprises: at least one cam follower connected to the at least one cam; anda gate support arm connecting the gate to the cam follower such that movement of the at least one cam follower causes movement of the gate. 12. The positive displacement compressor of claim 11, wherein the gate positioning system comprises means for urging the cam follower to maintain contact with the cam. 13. The positive displacement compressor of claim 1, wherein the rotor includes at least one hole or counterweight that aids in balancing the rotor. 14. The positive displacement compressor of claim 1, wherein the shaft comprises a drive shaft, and wherein the rotor is rigidly mounted to the drive shaft for rotation with the drive shaft relative to the rotor casing. 15. The positive displacement compressor of claim 1, wherein: the rotor casing has an inlet port and an outlet port,the compressor comprises at least one liquid injector connected with the rotor casing to inject liquids into the compression chamber,the gate separates an inlet volume within the compression chamber and a compression volume within the compression chamber,the inlet port is configured to enable suction in of working fluid, andthe outlet port is configured to enable expulsion of both liquid and gas. 16. The positive displacement compressor of claim 15, wherein: the outlet port is located near the cross-sectional bottom of the compression chamber,the compressor further comprises at least one outlet valve in fluid communication with the compression chamber, andthe outlet valve is configured to allow for the expulsion of liquid and gas. 17. The compressor of claim 1, wherein the sealing portion forms a dwell seal with the inner curved surface of the compression chamber.
