Abstract

1,058,224. Rotary compressors. POLYSIUS G.m.b.H. Oct.1, 1963, No.38683/63. Heading F1F. A rotary compressor of the Roots'-blower type comprises a pair of ancillary rotors or rotary sliders (4, 5), Figs. 1 to 14 (not shown), which rotate in synchronism with the main rotors or impellers (2, 3) and periodically come into contact with the lobes thereon whereby a compressible fluid e.g. air, is compressed in spaces or zones (8, 19) between the main rotors and the casing (1) before it enters a space (17) between the ancillary rotors, which space lies adjacent a delivery port (7). The portions (22', 24', 26') of each ancillary rotor which come into contact with the lobes of the associated main rotor have profiles similar to those of the portions (22, 24, 26) of each main rotor lying between the lobes whereby both pairs of rotors can be machined by the same tools.
