    摘要： The present invention relates to the mechanical engineering but namely : to the propulsion engineering. A compound piston ring for internal combustion engine is characterized in that a width B and b and thickness H and h of metallic bands used for manufacturing the plate-like rings and the tangential expanders are in the following correlations: b/B = 0,45 ± ± 0,15 and h/H = 0,85±0,15. A method for manufacturing plate-like twisted rings for compound piston ring is characterized in that after the polishing the spiral is taken away from the mandrel and the spiral surface is prepared (is cleaned, etched and degreased) before the step of chromium-plating, further the spiral is based on the mandrel of given diameter, the step of chromium-plating is carried out along the external diameter, further the spiral is taken away from the mandrel and is dehydrogenated at a temperature up to 250° C but before the step of spiral cutting into the separate rings the spiral is preliminarily based on a mandrel or in sleeve of given diameters. A method for manufacturing of the tangential expanders for compound piston ring is characterized in that after the step of forming serpentine spring coils the step of gradual decreasing of coils step value is carried out with the step of permanent fixing places of bend but the step of thrust shoulders forming is carried out with a subsequent decreasing coils of this step to a value which is no more than 5S, wherein the value S is the band width when the serpentine spring is formed of this band. A device for manufacturing serpentine springs characterized in that it is provided with an immovable cam-eccentric disposed inside of the roller with the pins and with mechanisms for a restraint of motion of the pins, the mechanisms are carried out in the form of copying guides disposed on the both sides from the guide roller in course of the band feeding, the surfaces of copying guides are equidistant to the cam-eccentric surface and the pins are made to move in the radial direction and are mounted being capable of engaging with the cam-eccentric and the mechanisms for their motion restraint. The technical result of the invention realization consists in that there is solved the problem of increasing the effectiveness of compound piston ring by means of providing a guaranteed adjacency of plate-like rings both in the axial direction and the radial direction.
