ABSTRACT:
A machine for compressing or expanding fluids in which a globoidal worm, having a plurality of threads with crests circumscribed by a surface generated by a rectilinear line and in meshing engagement with at least one toothed pinion, cooperates with a casing having at least one low pressure port and at least one high pressure port located in the immediate vicinity of the pinion. Each of the pinion teeth is provided with two substantially rectilinear flanks, the flank located on the side of the pinion nearest the low pressure port when one tooth is engaged in the worm being longer than the flank of the same tooth which is located nearest the high pressure port.
