FIELD: engines and pumps.
SUBSTANCE: rotary internal combustion engine sealing system contains radial and tangential seals. Radial seals are made in the form of pair of adjacent contact sealing plates located in slots of blades and individually spring-loaded to working surface of housing with radial rounded edges with chamfers inside sealing plates forming labyrinth-pocket. Each of sealing plates is connected to counter-weight by means of gears and parallel toothed racks installed both on sealing plates, and on counter-weights located in pairs on the left and on the right sides in slots of blades. Gears are installed in pairs on common axes fixed in walls of blades. Tangential seals are made in the form of semi-cylindrical self-adjusted inserts in zones of edges of rotor slots on both sides of blades with sealing plates spring-loaded by means of expanders to blades.
EFFECT: higher reliability and degree of pressurisation of seals.
