Abstract

The invention is a split sealing ring structure for pistons, which is placed in the groove of a piston, and includes a flexible steel internal ring as well as at least one external ring of soft iron material, and the internal ring meets the external ring in a conical surface that is angular to the plane of the ring structure, which includes a waved ring (8) of flexible material between the lower part of the piston (1) of the groove (3) in radial direction and the internal ring (4).
