Abstract (en)
[origin: US4764094A] PCT No. PCT/SU85/00061 Sec. 371 Date Mar. 20, 1987 Sec. 102(e) Date Mar. 20, 1987 PCT Filed Jul. 22, 1985 PCT Pub. No. WO87/00571 PCT Pub. Date Jan. 29, 1987.The screw machine comprises consecutively mounted screw mechanisms (6, 7 and 8, 9) incorporating coaxially arranged stators (10, 12 and 14, 16) and rotors (11, 13 and 15, 17) disposed therein whose axes are offset with respect to the central axis of the stators (10, 12 and 14, 16) by the amount of eccentricity "e" of the screw mechanisms (6, 7 and 8, 9). The screw mechanisms (6, 7 and 8, 9) are grouped into modules (4, and 5) and the modules proper are grouped into blocks (3). The axes of the rotors (11, 13, 15, 17) of the screw mechanisms (6, 7 and 8, 9) in the module (4 and 5) and the modules (4, and 5) proper in the block (3) are arranged symmetrically relative to the central axis.
