    Abstract: An oil-free rotary gas-compressor system includes an oil-free rotary gas-compressor (2) having a high, built-in pressure ratio and an injector arrangement (13) for injecting a vaporizable liquid, preferably water, into the compressor (2) for cooling the gas during the compression process. It is known in high-speed compressors to utilize water injection which is so restricted that the water is completely vaporized, to thereby obtain a good cooling effect. The efficiency of the compressor is limited, however. In known systems, high compressor efficiencies are obtained by injecting large quantites of water, although the compressor speed must then be considerably reduced, resulting in a lower compressor capacity. According to the present invention, a correspondingly high efficiency can be obtained, however, in a high-speed compressor when the water is injected into the compressor in a weight quantity which is greater than the maximum amount of liquid permitted for obtaining a complete vaporization of the liquid during the compression of the gas up to an amount that is four times greater than said maximum amount.

    Abstract: A rotary screw compressor having two rotors, liquid injection, a liquid separator (10), and a hydraulic thrust balancing piston (11) connected to at least one of the rotors. In order to vary the balancing force if suction and delivery pressures vary, there is provided first (5) and second (4) throttling devices in the return pipe from the oil separator to the liquid injection port. Between the first and second throttling devices there is a connection to a pipe branch (7) which ends in a cylinder (14) which houses the balancing piston (11). The balancing pressure acting on the balancing piston (11) will thereby vary as suction and delivery pressures vary in a way determined by the relation between the degree of throttling in the two throttling devices.

    Abstract: A screw compressor of the kind incorporating at least one male rotor and one female rotor, with helically extending lands and grooves. The female rotor (1) is injection moulded from a plastics material having a modulus of elasticity of at most 25,000 N/mm.sup.2. The lands (3) of the female rotor have a thickness (a) which is so adapted to the modulus of elasticity of the plastics material as to allow the lands to be deflected resiliently when clashing with the other rotor (2), as a result of dimensional deviations of the order likely to occur during hardening or curing of the plastics material, or at prevailing temperature variations, but not as a result of the pressure exerted by the working fluid. Due to the injection moulding the surface smoothness is fine enough to make subsequent finishing unnecessary and damages caused by lack of machining are avoided because of the resilient deflecting of the lands of the female rotor when clashing with the other rotor.
