体機械。 A male rotor and a female rotor, which rotate in opposite directions while meshing with each other, are hermetically housed in a cavity formed in the casing, and are hermetically and slidably fitted in a groove communicating with the suction port. In a screw-type rotary fluid machine in which the capacity is controlled by moving a slide valve that limits a portion of the cavity along the axial direction, one end communicates with the suction port and the other end communicates with the inner end surface on the suction side of the cavity. A screw having a suction hole that opens at the rotor, and a suction passage whose one end communicates intermittently with the opening at the other end of the suction hole as the rotor rotates, and whose other end opens at the tooth surface of the rotor. rotary fluid machine.
