置に開口部を設けたことを特徴とするスクリュ圧縮機。 −[Scope of claim for utility model registration] Screw compression in which a pair of male and female screw rotors that mesh with each other are housed in the rotor chamber of a casing, and after gas is sucked in from one side of the casing, compressed, and then the compressed gas is discharged from the other side. In the machine, a through hole that communicates with the gas suction part of the casing is provided in the wall near the suction side of the rotor and rotor chambers so as to be openable and closable, and the opening of this through hole facing the rotor chamber is opened from the groove of the screw rotor. It is formed in a small mountain and parallel to the groove, and is necessary to equalize the pressure in the groove and the gas suction part within the time it takes for one of the grooves to pass over the opening when the through hole is open. A screw having a minimum cross-sectional area, and having openings at positions where the volumes of two types of confined spaces, which can be changed by opening and closing a through hole, correspond to power sources of two types of frequencies. compressor. −
