Abstract RU 2518778 C1

FIELD: machine building.

SUBSTANCE: packing seal is made from resilient elastic material in the form of a cup with a central hole in the bottom for operating fluid supply and with internal surface made as a truncated cone whose bigger base is turned to the mouth. The outer seal surface is made as two truncated cones matching by their bigger bases, their generatrices are inclined in respect to the straight line drawn through the cross point of the said generatrices parallel to the central seal axis, at an angle of 15-20°. The generatrix of the truncated cone oriented to the cup mouth is longer than the generatrix of the truncated cone oriented to the bottom.

EFFECT: simplified design and improved reliability.
