ABSTRACT A seal assembly for a rotary valved internal combus- tion engine is disclosed. The seal assembly comprises longitudinal side meals for axially sealing an interface between a cylindrical valve housing and a complementary valve rotor body therein. Circumferential ring seals are spaced apart along the valve rotor body for isolating inlet or exhaust ports which extend diametrically through the rotor. The ring seals are provided with a novel means for biasing the seals against the rotor. Spacers are provided for locating and retaining the seals in position within the housing, with bearing rings between the spacers for rotationally supporting the rotor. The assembly also includes means for locating the spacers properly in a head of the engine and for properly orien- ting the end seals.
