Abstract
Perfeccionamientos en pistones de varias partes para motores de combustión interna, en particular para motores diesel grandes, con una parte superior de pistón que está constituida por un cuerpo de pistón y una parte de envolvente de pistón, que, a través de una superficie anular interior, perpendicular al eje del pistón y perteneciente a un apéndice anular situado en el lado inferior del cuerpo del pistón, se apoya sobre una superficie anular interior opuesta, radialmente biselada hacia fuera, de una parte inferior de pistón, formando una rendija anular que se ensancha radialmente hacia fuera, y que está fijada a la parte inferior del pistón por medio de tornillos de unión interiores que discurren paralelos al eje del pistón y atraviesan las superficies anulares interiores, caracterizados porque en la zona del pistón y atraviesan las superficies anulares interiores, caracterizados porque en la zona del pistón radialmente exterior respecto a las superficies anulares interiores están conformadas en la parte superior del pistón y en la parte inferior del pistón dos superficies anulares exteriores perpendiculares al eje del pistón, paralelas y dispuestas a cierta distancia una de otra, y porque en la zona radialmente exterior del pistón están dispuestos unos tornillos de unión exteriores, después del apriete de los cuales vienen a quedar completamente asentadas una en otra las superficies anulares interiores y también las superficies anulares exteriores.
