Claims (6)

1. In a rotary engine of trochoidal type having a housing comprising side walls' and a peripheral wall/ defining an engine cavity, a shaft transpiercing the side walls and having an eccentric t v-portion disposed within the cavity, a rotor^ rotatably mounted on the eccentric and bearing on one side face^ a gear A> in engagement with a gear^borne by the adjacent side wall, the improvement coiu-prising: each of the gears having a gear base portion with gear teeth extending axially therefrom.
2. The combination recited in Claim 1, wherein the teeth of each gear are connected exclusively at one end of the gear teeth to their respective gear bases.
3. » The combination recited in Claim 2> wherein the inner and outer diameters of the teeth of each gear are substantially equal to the respective inner and outer diameters of their respective gear bases ,
4. The combination recited in Claim 1, wherein the roots of the teeth of each gear are connected to one another by annular extensions of their respective, gear bases.
5. » The combination recited in Claim 1, wherein the flanks of the profile of the teeth of each gear are on circular arcs approximating involute toothing.
6. The combination recited in Claim 1, wherein the gears are formed of sintered material. For the Applicants
