ABSTRACT:
A piston for a reciprocating machine includes a split piston ring which is located in a circumferential groove in the cylindrical wall of the piston. The piston is adapted to be located in a cylindrical bore so that the piston ring sealingly engages the bore with a gap between its ends, the gap being fully underlaid and sealed by a contiguous unbroken annular supporting ring, a spring being provided to maintain the ends of the piston ring in engagement with the supporting ring.
