Abstract

La presente invención se refiere a un pistón de dos piezas para motores de combustión interna, compuesto de una cabeza hecha de un metal ferroso a una aleación de aluminio y una falda hecha de aluminio o de una aleación de aluminio, estando separada la falda de la cabeza y conectada por mediode un perno estrangulado a un par de protuberancias de perno en la porción inferior de los miembros soportadores que dependen de la cabeza; caracterizado dicho pistón porque la cabeza de pistón está provista de una cámara enfriadora cerrada, anular, situada entre la banda anular y la concavidad de combustión del pistón.The present invention relates to a two-piece piston for internal combustion engines, consisting of a head made of a ferrous metal to an aluminum alloy and a skirt made of aluminum or an aluminum alloy, the skirt being separated from the head and connected by means of a throttled bolt to a pair of bolt protuberances in the lower portion of the head-dependent supporting members; Said piston characterized in that the piston head is provided with a closed, annular cooling chamber located between the annular band and the piston combustion concavity.
