SEAL Russian patent published in 2019 - IPC F16J15/32 

FIELD: instrument engineering.

SUBSTANCE: invention relates to seal (1) comprising first sealing edge (2) with first sealing surface (3) for abutting on first structural element (4) and at least one other sealing edge (5) with at least one other sealing surface (6) for abutting against at least one other structural element (7). Sealing edges (2, 5) are connected to each other in base area (8) of sealing edge (1) and each of them freely protrudes on its opposite base area (8) of edge end (9, 10), on which there are sealing surfaces ( 3, 6). On their sides, opposite their sealing surfaces (3, 6), each of them has one surface (12, 13) of abutment. Surfaces (12, 13) of abutment in non-loaded initial position are located at distance from each other. Seal (1) has working position intended for sealing of structural elements (4, 7), in which sealing edges (2, 5) adjoin each other by their adjoining surfaces (12, 13), resting on each other. Other sealing edge (5) has petal lobe (20) which in the working position of seal (1) forms radially pressure-loaded surface (21).

EFFECT: seal is disclosed.
