Abstract

Pistón para motores de combustión interna, con una parte inferior que circunda a la zona del vástago y una parte superior del pistón unida con ésta a través de tornillos de dilatación y que forma el fondo y la zona anular en el que los tornillos de dilatación en la parte inferior del pistón se apoyan en casquillos de dilatación que entran en taladros respectivos de la parte inferior del pistón, y en el que el apoyo entre el casquillo d e dilatación y la parte inferior del pistón se efecto a través de una superficie convexa del casquillo de dilatación y de una superficie correspondientemente cóncava de la parte inferior del pistón siendo el radio de la superficie convexa más pequeño que el de la superficie correspondientemente cóncava, caracterizado porque el centro del medio de curvatura de la superficie de apoyo convexa en forma de corona particular del casquillo de dilatación, se sitúa junto al eje longitudinal.del casquillo de dilatación, a diferencia del centro de la superficie contra el casquillo de dilatación presenta hacia la superficie de apoyo una baza desmontable que se puede partir.
