ABSTRACT:
A dynamic sealing ring made of a resilient flowable material such as an elastomer throughout, characterized by its cross-sectional configuration which in its free form is uniform and generally rectangular with arcuate smoothly contoured convex lobes at each of its corners, with its two opposed axially extending surfaces bearing additional annular convex sealing lobes in unequal numbers disposed in non-opposite relation between the adjacent corner lobes and separated therefrom and from each other by concavities and extending outwardly therebeyond a short distance to effect a more perfect seal, particularly when applied in encircling relation to a reciprocating piston rod and subjected to high gaseous pressures from a single direction or as a piston seal.
