RING SEAL FOR IMPLEMENTATION OF ROTARY SEAL BETWEEN TWO CYLINDRICAL ELEMENTS Russian patent published in 2022 - IPC F16J15/00

Abstract RU 2774256 C2

FIELD: sealing means.

SUBSTANCE: invention relates to ring seal (30, 32, 34) that contains main case (42) made with the possibility of provision of seal due to a static contact relatively to first cylindrical element (4), and first circumferential edge (64) made with the possibility of interaction due to friction with cylindrical surface (14) of second cylindrical element (10), while mentioned cylindrical elements (4, 10) are essentially coaxial and are installed with the possibility of rotation relatively to each other. Main case (42) contains front surface (48) made with the possibility of axial contact with the front surface of first cylindrical element (4), while main case (42) contains second circumferential edge (52) radially opposite to first circumferential edge (64) and made with the possibility of radial contact with cylindrical surface (38) of first cylindrical element (4).

EFFECT: obtaining ring seal for the implementation of rotary seal between two cylindrical elements.
