FIELD: engines and pumps.
SUBSTANCE: sealing assembly of piston engine is intended for internal combustion engine with sealed working chamber (3) of variable volume. Assembly contains open sealing ring shaped in the form of annular flange (8) with sealing surface (9), and connected with it bushing (10) with outer cylindrical surface which is in contact with the sealing surface of engine cylinder (1), and device limiting displacement of the sealing assembly relative to piston (2) in direction of its longitudinal axis (7). Assembly is provided with closed continuous shielding element (5) with screening annular flange (6) located on the side surface of annular flange (8) of sealing ring, closest to sealed working chamber (3) of the engine. Screening annular flange (6) has external diameter exceeding internal diameter of sealing ring bushing (10).
EFFECT: technical result consists in improvement of engine capacity gas density upon increased reliability of sealing operation and reduced thermal tension of the piston.
