Abstract
There is provided a rotary internal combustion engine (20) comprising a plurality of rotors (21) each having a plurality of lobes (22) for intermeshing with lobes of other rotors to form successive combustion chambers. Axial seal elements (60, 61) are provided at the rotor tips and trailing tips of the rotors respectively. Circumferential axial edge seals (59) are also provided to interconnect the axial seals. The seals engage sealing plates (30) on each axial side of an engine housing (29) so as to effect the combustion chambers. Fuel inlets and ignition means are provided at suitable locations, as are exhaust means.
