Abstract
A rotary internal combustion engine has: a rotor; a housing circumscribing a rotor cavity, the rotor received within the rotor cavity, the housing having a peripheral wall and a side housing assembly secured to the peripheral wall, the side housing assembly having plates located at spaced apart ends of the peripheral wall, the plates defining seal running surfaces in sealing engagement with opposed end faces of the rotor, the plates made of silicon carbide.
Claims16
A rotary internal combustion engine comprising:
- a rotor;
- and
- a housing circumscribing a rotor cavity receiving the rotor, the housing having a peripheral wall, end walls secured to opposed ends of the peripheral wall, and silicon carbide plates located on inner sides of the end walls and facing the rotor cavity, the silicon carbide plates defining seal running surfaces in sealing engagement with end faces of the rotor, the silicon carbide plates being movable relative to the end walls,
- wherein peripheries of the silicon carbide plates are sandwiched between the peripheral wall and the end walls.
A housing for a rotary internal combustion engine, the housing comprising:
- a peripheral wall;
- end walls secured to opposed ends of the peripheral wall, the peripheral wall and the end walls circumscribing a rotor cavity for receiving a rotor therein;
- and
- silicon carbide plates located on inner sides of the end walls and facing the rotor cavity, the silicon carbide plates defining seal running surfaces in sealing engagement with end faces of the rotor, pockets located between the end walls and the silicon carbide plates, the pockets configured for circulating a liquid coolant.
