RADIAL SEALS OF ROTARY-PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2021 - IPC F01C19/02 F02B55/00 F16J15/16

Abstract RU 2741176 C1

FIELD: engine building.

SUBSTANCE: invention relates to rotary-piston internal combustion engines with contact system of seals. Radial sealing of rotary-piston internal combustion engine is made in form of sliding elements consisting of intercerammatrix composite material of the following composition, wt%: magnesium oxide (MgO) - 4.0-5.0; hexagonal boron nitride (BN) - 2.0-3.0; boron oxide (B₂O₃) - 1.0-2.0; α-nitride of silicon (Si₃N₄) - the rest.

EFFECT: technical result consists in improvement of reliability, serviceability and resource of radial seals.
