Piston-piston ring assembly for internal combustion engine, comprises piston top which is provided with piston ring in annular groove, where piston ring has circumferential line

摘要

The piston-piston ring assembly comprises a piston top which is provided with a piston ring in an annular groove (20). The piston ring has a circumferential line, where the annular groove has other circumferential line (21) having a maximum (23). The circumferential line is a central periphery line. Independent claims are also included for: (1) a piston for a piston-piston ring assembly; and (2) a piston ring for a piston-piston ring assembly.
