Abstract

Mejoras 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, en 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, caracterizado porque el alineador comprende una varilla curva que tiene un radio de curvatura igual a dicho radio de curvatura de dicho distanciador-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 distanciador-ensanchador y que tiene medios formados en dicho primer extremo entre tramosintermedios del distanciador-ensanchador para limitar el deslizamiento de dicho alineador en dicho distanciador-ensanchador, teniendo además dicha varilla un segundo extremo que se extiende a través de una pluralidad de aberturas de tramo intermedio en el extremo opuesto del distanciador-ensanchador en un arco de al menos 75º en dicho estado libre de dicho diatanciador-ensanchador y estando libre para deslizarse a través de dicha pluralidad de aberturas de tramo intermedio.
