FIELD: mechanical engineering; rotary engines of different applications.
SUBSTANCE: proposed device contains sealing element fitted in piston slot and set of plates made of antifriction heat-resistant material. Slot of piston is essentially trapezoidal section radial groove. Relations of piston slot parameters are given in description of invention, as well as shape and dimensions of first and second resilient elements. Length of second resilient element provides forming of projection of definite height on ball surface of piston.
EFFECT: improved reliability of sealing.
