SEALING RING Russian patent published in 2009 - IPC F16J15/00 

FIELD: machine building.

SUBSTANCE: present invention pertains to sealing techniques. On the sealing ring, on the side of the ends in the cross section, there are oxygonally arranged rounded projections. The inner radial surface is matched with elastic annular curvature and continuous curvature, matched with the radial projection of the rectangular section. The height of the rounded projection on the side of the latter is less than the height of the rounded projection of the other end. The formed conical, joining annular curvature and continuous curvature, forms an acute angle with the axis of the cross section of the sealing ring. The annular curvature and the continuous curvature are made on the base with radial junctions. The radial projection coming out of the radial cross section is also rounded.

EFFECT: improved design parameters of the sealing ring.
