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.

Abstract
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.
