Abstract
Pistón perfeccionado para motores de combustión interna, de aleación ligera (1) que comprende una parte superior (2), una falda (4) par de soportes del pasador del pistón (6) que se forman mediante dos partes ensanchadas de la falda (4) que se extiende desde la parte superior (2), caracterizado porque nada una de las partes ensanchadas tiene una ranura de descompresión (9) que se extiende sustancialmente en un plano perpendicular al eje común de los soportes (6) a lo largo de la extensión de la superficie interior (7) de la falda (4) desde la cual sobresalen las partes ensanchadas, y porque cada una de las ranuras de descompresión (9) se extiende desde esta parte (10) de la superficie exterior del respectivo soporte (6) que se halla s alejado de la parte superior (2) a un plano sustancialmente coincidente con el plano perpendicular al eje del pistón (1) que contiene el eje de los soportes.
