Abstract

1376864 Rotary positive - displacement machines AUDI NSU AUTO UNION AG and WANKEL GmbH 9 May 1973 [9 May 1972] 22024/73 Heading F1F In a trochoidal-type machine such as an I.C. engine, gear-wheels 9, 10 controlling the planetary motion of the piston 7 have teeth 13, 14 extending axially from respective base rings 15, 16, which are fixed to the piston and housing, respectively. The gear-wheels may be made by sintering and the teeth may have involute flank profiles. The ring 16 may be constituted by the shell of a plain bearing for the shaft on which the piston is mounted, Fig. 1 (not shown). The roots of the teeth of each wheel may be interconnected by an annular projection on the respective base ring, Fig. 3 (not shown).
