Abstract

992,226. Rotary blowers. H. MAHLE, and E. MAHLE, [trading as MAHLE KOMMGES.]. April 24, 1964 [May 16, 1963], No. 17067/64. Heading F1F. A rotary blower comprises first and second toothed pistons 1, 2, Fig. 2, rotatable in opposite directions in intersecting parallel bores 32, 31 in a housing 3 having a suction chamber 33, a pressure chamber 35 and a part 34 in an end wall obturated by the pistons and communicating with the pressure chamber in which only the leading edges 21<SP>1</SP> - - 24<SP>1</SP> of the teeth of the second piston 2 are in sliding contact with the housing bore 31 so that passages 36 therebehind interconnect the displacement cavities of the two pistons to equalize the pressures therein prior to the uncovering of the port 34 by a cavity in the second piston. The projecting parts of the teeth of the second piston in sliding contact with the housing bore may be made of material having good anti-friction properties such as polythene tetrafluoride. Further, recesses 37 may be provided in either one or both end walls of the housing to give further pressure equalization. The piston 1 rotates at twice the speed of the piston 2.
