Abstract

The invention relates to a reciprocating piston machine with at least one piston (5). Said piston is provided with at least one piston ring (6) that is located in a corresponding piston ring groove (7) of the piston (5), said piston ring groove having a supporting surface (8) that pertains to the piston ring (6). The aim of the invention is to facilitate a wear-free operation and high durability of such a piston despite high pressure in the area of the supporting surface (8). To this end, the piston ring (6), at least in the radial outer area of the lower surface facing the supporting surface (8), is provided with recesses (14, 15) which form oil pockets (13) and adjacent supporting areas (18). A filling (16, 17) is allocated to said oil pockets that consists at least partially of aluminum bronze with a wear resistance that differs from the wear resistance of the base material of the piston ring.
