Abstract

PURPOSE: To obtain a screw compressor having capacity control property capable of vying with others for its efficiency at the time of performing reciprocatory compression by providing separately a slide valve severing from a main slide valve.
CONSTITUTION: A slide valve 430 severed separately from a main slide valve 330 positioned at the gearting portion of male and female rotors 1, 2 is provided at least on one side of either a bore on the side of a male rotor 1 or a bore on the side of a female rotor 2, the slide valve 430 on this bore side is slid together with the main slide valve 330 in the direction of rotar axles. The above-mentioned constitution allows to design them on the optimal radial port at the time of 100% capacity so that improvement can come up to the performance at the time of 100% capacity at the same time to widely the capacity control property.
