A screw machine () has a rotor housing () defining overlapping bores (--). Female rotor () is located in bore (-) and male rotor () is located in bore (-). A wear resistant coating is deposited on the tips (--) of the rotors. A conformable coating is deposited on the valleys (--) of the rotors. A conformable coating is depsoited on the surface of the bores coacting with the rotors.

A screw compressor includes a housing and a screw rotor disposed in the housing and rotatable relative to the housing for compressing a refrigerant, the housing and the screw rotor having a rest condition, and an operating condition wherein at least one of the housing and the rotor deflect from the rest condition, and structure for at least one of reducing deflection from the rest condition and evenly distributing deflection from the rest condition when the rotor is in the operating condition, whereby clearance between the housing and the rotor is optimized in the operating condition.

Screw compressors with rotor and casing design for controlling deflections

A compressor for compressing refrigerant in an air conditioning or refrigeration system, including a housing having a suction port, a discharge port, and a compression chamber, a mechanism for producing a compression cycle for compressing the refrigerant, wherein the compression cycle occurs in the suction port, discharge port and compression chamber, and a mechanism for providing liquid refrigerant into the compression cycle at a desired location for reducing pressure pulsations and associated radiated noise produced during the compression cycle.

Liquid injection for reduced discharge pressure pulsation in compressors

A screw machine ( ) has a rotor housing ( ) defining overlapping bores ( - - ). Female rotor ( ) is located in bore ( - ) and male rotor ( ) is located in bore ( - ). A wear resistant coating is deposited on the tips ( - - ) of the rotors. A conformable coating is deposited on the valleys ( - - ) of the rotors. A conformable coating is depsoited on the surface of the bores coacting with the rotors.
