摘要： A method for processing a constructed, liquid-cooled piston of an internal combustion engine, the piston including an upper piston part and a lower piston part, which are supported by a joining plane and are connected to each other in a bonded manner. An electrochemical method, such as electrochemical machining, is used to produce a passage opening or a hole in the piston. By means of the method, material is selectively removed after the completion of the upper part piston, the lower piston part, or the piston after the two piston parts have been joined. The electrochemical machining allows an arbitrarily geometrically designed topography having at least one passage opening, a hollow, or an oil pocket in cooling areas or non-cooling areas to be created on the piston.

摘要： An elastic piston ring, generally employed as a scraper ring and also known as an oil control ring, of spring steel of the Usection type, made from a strip of rolled steel comprising a grooved web and flanges cut-out in alternate folded portions so as to have a cross-section of U-shape, the said band being then cut into lengths which are rolled to the shape of a ring, the final lateral surfaces of the said piston ring each constituted by the successive sections of each flange being obtained by flow of the metal in an appropriate tool, by an operation known as forging, without other machining action on the said surfaces and a method for its manufacture.
