SYSTEM FOR LINEAR DISPLACEMENT AND COMPOSITE SEALING (VERSIONS) Russian patent published in 2013 - IPC F16J15/24 

FIELD: machine building.

SUBSTANCE: composite sealing comprises a metal spring fixed in an elastomer body, which is connected with a polymer ring. The spring may comprise a cantilever closing metal strip. Elastomer and polymer are mechanically fixed with the help of radial elements. Elastomer comprises contact surfaces, configured in the form of radii stretching outside to improve load at the front edge and to remove oil from dynamic surface.

EFFECT: when using in hydraulics - a sealing prevents leakage of a working liquid and ingress of foreign particles.
