Abstract

Przedmiotem wynalazku jest ruchomy pierścień tłokowy do tłoka (1) silnika spalinowego posiadającego obwodowe rowki (4) pierścieniowe wykonane pod kątem 30° do poziomej powierzchni tłoka pracującego w tulei cylindrycznej. Ruchomy pierścień tłokowy składa się z 60 identycznych płytek, które po umieszczeniu w rowku pierścieniowym razem tworzą pierścień. Dzięki złożonej konstrukcji pierścienia oraz szczelinie będącej wynikiem większej wysokości rowka pierścieniowego od wysokości płytki pierścieniowej możliwy jest ruch krawędzi pierścienia stykającej się z tuleją cylindryczną pod wpływem tarcia o powierzchnię tulei. Dzięki zmianie położenia krawędzi zewnętrznej pierścienia dochodzi do zaniku styku pomiędzy powierzchnią pierścienia a powierzchnią tulei cylindrycznej. Pozycja w której nie ma styku powierzchni pierścienia z powierzchnią tulei cylindrycznej nazywana dalej będzie "pozycją górną" pierścienia. W wyniku przejścia pierścienia w "pozycję górną" w układzie współpracy ruchomy pierścień tłokowy-cylinder tarcie pomiędzy elementami spada do poziomu minimalnego i pomijalnego względem innych sił tarcia występujących podczas pracy tłoka.The subject of the invention is a movable piston ring for a piston (1) of an internal combustion engine having circumferential grooves (4) annular made at an angle of 30 ° to the horizontal surface of the piston operating in a cylindrical sleeve. The movable piston ring consists of 60 identical plates, which when placed in the annular groove together form a ring. Due to the complex structure of the ring and the gap resulting from the higher height of the annular groove than the height of the annular plate, the edge of the ring in contact with the cylindrical sleeve can be moved by friction against the surface of the sleeve. By changing the position of the outer edge of the ring, the contact between the ring surface and the surface of the cylindrical sleeve disappears. The position in which there is no contact of the ring surface with the surface of the cylindrical sleeve will be referred to as the "upper position" of the ring. As a result of the transition of the ring to the "upper position" in the cooperation system, the movable piston ring-cylinder, the friction between the elements decreases to a minimum and negligible level relative to other frictional forces occurring during the piston operation.
