Abstract

The compressor is of the type having a pair of co-operating rotors (20, 22) with parallel rotation axes and dissimilar asymmetric lobed configurations. The rotor (22) has a profile (in cross-section) that is greater in area than that of the other rotor (20) and comprises a sector II of radius R, which is somewhat greater than the radius r of the outer edge of a discharge port (44). The gas flow is thereby improved. Balancing plugs (100) may be lodged in the rotors. Strips (70, 72) of a material e.g. a lead-tin alloy, that can be worn-down easily may be attached to the rotor (22) and the inner peripheral wall of the casing, Fig. 5 (not shown), to facilitate "lapping-in" of the rotors. Sealing strips made of said material may also be attached to the casing end-walls, Figs. 9a to 11 (not shown). The compressor may comprise two stages disposed one above the other, Figs. 1 (a)-(c) (not shown). <IMAGE>
