Abstract
Pistón de metal ligero para motores de combustión interna, con cubos de bulón apoyados en la culata del pistón esencialmente a través de apuntalamientos axiales, cuyas superficies finales que se hallan exteriormente en la dirección del bulón, presentan una separación menor de la que corresponde al diámetro de la culata de pistón, estando previstas en la culata de pistón escotaduras a modo de ventanas que dejen libres los ojos del bulón en la dirección del bulón, con cuyos bordes están apuntalados los cubos de bulón partiendo de sus ojos, caracterizado porque los apuntalamientos, a menos en las zonas colindantes a las superficies de deslizamiento del pistón, se hallan en la superficie lateral de un tronco de cono con un ángulo de conicidad de menos de 110º.
