ABSTRACT:
A continuous ring with inside diameter (D.sub.in.sup.R) larger than the outside diameter (D.sub.out.sup.R) of the piston irrespective of conditions of operation. The ring's outside diameter when measured outside the cylinder equals or slightly exceeds the inside diameter of the cylinder. The ring is sized and designed according to various parameters determined so as to prevent piston seizing in the cylinder.
