Abstract

1324120 Piston rings GOETZEWERKE FRIEDRICH GOETZE AG 21 Dec 1970 [20 Dec 1969 3 Sept 1970] 60616/70 Heading F2T The annular spring 2 in the region bridging the gap 3 in the piston ring 1 is provided with a resilient intermediate piece 4 that is more resistant to wear than the rest of the spring. The wear portion may extend over 90 degrees and be formed integral with, or separate from, the rest of the spring. It may be made of thick wire or closer turns or corrugations than in the rest of the spring. As shown in Fig. 2, the outer surfaces 5 of the coils in the wear portion may be flattened. The wire for the coils may alternatively be of rectangular cross-section.
