Abstract

See full text

A liquid-supply-type screw compressor can suppress a rise in temperature of a liquid while reducing work for stirring the liquid. The compressor has male and female rotors, male- and female-rotor-side working chambers formed at grooves of the male and female rotors, respectively. The compressor also has a liquid supply nozzle arranged on one side in the rotor axial direction which is a low-pressure side of an intersection at which a high-pressure-side cusp intersects a ridge line of a trailing lobe tip of the female rotor that defines a female-rotor-side working chamber, the nozzle supplying liquid to the male-rotor-side working chamber; and a liquid-supply nozzle arranged on the other side in the rotor axial direction which is a high-pressure side of the intersection, and supplies the liquid to the male-rotor-side working chamber, and the liquid supply amount of the nozzle is made greater than the amount of the other liquid-supply nozzle.
