Abstract

A meshing-screw compressor, or expander, comprises twin screw-rotors, or "spindles", (1a,b; 2a,b) each rotor having a helical slot (9) in each half thereof whose cross-section decreases toward the rotor center. The sides of the slot (9) are constituted by stepped flats (16) standing perpendicular to the rotor axes. Each rotor may thus be formed by a stack of laminae, or "disks", on a shaft 4 (as indicated in the right-hand half of Fig. 1). Channels 12, 14 for low and high pressure working-fluid may be disposed in the casing 7 as shown. <IMAGE> [GB2030227A]
