Abstract

Perfeccionamientos en los segmentos de pistón, del tipo que comprende un distanciador-ensanchador circular para su uso en un segmento de pistón de control de aceite que tiene un radio de curvatura en estado libre y extremos partidos de ensanchador y que incluye una pluralidad de cabezas interiores y exteriores alternas, concéntricas y espaciadas circunferencialmente unidas en una sola pieza por una pluralidad de tramos intermedios substancialmente divergentes y aberturas de evacuado de aceite formadas una en cada uno de dicha pluralidad de tramos intermedios, y un alineador deslizante, caracterizados porque el alineador comprende una varilla curva, con un radio de curvatura igual a dicho radio de curvatura de dicho destanciador-ensanchador o inferior al mismo, teniendo dicha varilla un primer extremo que se extiende a través de al menos una abertura de tramo intermedio junto a un primer extremo de dicho espaciador-ensanchador y que tiene medios formados en dicho primer extremo entre tramosintermedios adyacentes de distanciador-ensanchador para limitar el deslizamiento de dicho alineador en dicho espaciador-ensanchador, teniendo además dicha varilla en segundo extremo que se extiende a través de una pluralidad de aberturas de tramo intermedio en el extremo opuesto del distanciador-ensanchador y estando libre para deslizarse a través de dicha pluralidad de aberturas de tramo intermedio, terminando dicho segundo extremo de varilla en una cara achaflanada dirigida hacia adentro para permitir que dicho segundo extremo cabalgue sobre bordes opuestos de dicha pluralidad de aberturas de tramo intermedio.
