Abstract

LA INVENCION SE REFIERE A UN PISTON, ESENCIALMENTE DE METAL LIGERO PARA MOTORES DE COMBUSTION, CON UN VASTAGO DE PISTON (10) ESENCIALMENTE CERRADO EN DIRECCION AL PERIMETRO, CON APOYOS PARA LOS BULONES (13), OPUESTOS DIAMETRALMENTE EN DIRECCION AL EJE DEL PISTON (A), Y CON DOS SECTORES DE PARED PORTANTES DEL VASTAGO (11,12), QUE PERSISTEN POR ELLO EN EL VASTAGO DEL PISTON, EN LA PARTE DE PRESION Y CONTRAPRESION, POR LO QUE EL SECTOR DE PARED PORTANTE DEL ARBOL (12) EN LA PARTE DE PRESION ES MAYOR AL MENOS EN DIRECCION AL PERIMETRO DEL VASTAGO, QUE EL SECTOR DE PARED PORTANTE DEL ARBOL DE CONTRAPRESION. PARA PODER DESVIAR LAS FUERZAS LATERALES QUE ACTUAN SOBRE LAS SUPERFICIES PORTANTES DE FORMA ELASTICA, Y CON SEGURIDAD SOBRE LA CONSTRUCCION TOTAL DEL PISTON, LOS DOS SECTORES DE PARED (20) DEL VASTAGO (10) QUE UNEN A LAS DOS SECTORES DE PARED PORTANTES (11,12), ESTAN CURVADOS DE FORMA CONTINUA CONVEXAMENTE Y HACIA AFUERA, RESPECTIVAMENTE AL MENOS EN EL EXTREMO DEL VASTAGO ABIERTO, DEBAJO DELOS APOYOS PARA LOS BULONES (13). LA CONFIGURACION DE LA SECCION TRANSVERSAL DEL VASTAGO DEL PISTON PUEDE SER DESIGNADO PUES COMO "EN FORMA DE HUEVO".
