1. A rotor for a rotary internal combustion engine comprising:
a body having first and second axially spaced apart end faces, and a peripheral face extending between the end faces and defining at least three circumferentially spaced apex portions, the first and second end faces each having a groove defined therein between each of the apex portions and each adjacent one of the apex portions, the grooves of the first and second end faces being disposed adjacent to and radially inwardly of the peripheral surface of the rotor; at each of the apex portions:
an apex seal protruding radially from the peripheral face of the body and being biased radially away therefrom, andfirst and second end seals received in a corresponding recess defined in the first and second end face, respectively, the first end seal protruding axially from the first end face and being biased axially outwardly away therefrom, and the second end seal protruding axially from the second end face and being biased axially outwardly away therefrom, the apex seal being engaged with the first and second end seals; a first face seal located in each groove of the first end face and extending between adjacent ones of the apex portions, each first face seal being biased axially outwardly away from the first end face, each first face seal having opposed curled ends each abutting the first end seal of a respective one of the adjacent apex portions; and a second face seal located in each groove of the second end face and extending between adjacent ones of the apex portions, each second face seal being biased axially outwardly away from the second end face, each second face seal having opposed curled ends each abutting the second end seal of a respective one of the adjacent apex portions. |
