ABSTRACT:
A rotary engine, such as a rotary internal combustion engine, a rotary pump, a rotary compressor or the like, comprises a housing defining a cavity with a n-lobed epitrochoidal shaped wall, a n+l lobed rotor within said cavity and movable in a planetary fashion, n being 1,2,3. . . and a main crank shaft with an eccentric supporting said rotor. The engine further comprises a transmission installed between the rotor and the main crank shaft, the transmission ratio of which being based on a certain ratio between the rotation of the rotor and the rotation of the main crank shaft such that during rotation of the rotor the shape of the outer envelope of the rotating rotor is exactly the same as the shape of the wall of the cavity.
