ELASTIC SELF-TIGHTENING METAL GASKET Russian patent published in 2017 - IPC F16J15/00 

FIELD: machine engineering.

SUBSTANCE: elastic self-tightening metal gasket has two symmetrical seal AC profile runners, section located between the solid elastic jumper with holes for supply to the internal cavity of the gaskets working environment, the pressure of which creates the effect of self-tightening. The jumper has an arched shape with a thickness less than symblo sealing its affiliation with bulge towards the outer or the inner diameter. The jumper can be performed with the slits freeform evenly spaced along the entire height of the circumference.

EFFECT: getting higher value of specific pressure on the sealing surfaces, which improves the ability of the sealing gaskets.
