Abstract

LA PRESENTE INVENCION SE REFIERE A UN DISPOSITIVO PARA GIRAR Y ENDURECER SIMULTANEAMENTE, POR INDUCCION ELECTRICA DE SUPERFICIES DE APOYO (2A; 3A) DE PISTONES ALTERNATIVOS (2; 3), SITUADOS UNO AL LADO DEL OTRO Y ORIENTADOS EN UNA LINEA CENTRAL, DE UN EJE DE CONTROL (1) DOTADO DE INDUCTORES (10; 11) QUE INCLUYEN DICHOS PISTONES ALTERNATIVOS (2; 3) CON UN ANGULO MAXIMO DE 180°. CADA INDUCTOR TIENE AL MENOS DOS O MAS PATILLAS (12, 13; 14, 15) PARALELAS ENTRE SI Y SITUADAS MAS ALLA DE LA CURVATURA DE LAS SUPERFICIES DE APOYO (2, 3), ENCONTRANDOSE UNA PATILLA SITUADA EN EL LADO DE LA ZONA SUPERPUESTA (5) DE LOS PISTONES ALTERNATIVOS (2B; 3B), Y LA OTRA CONECTADA A LA ZONA DEL BORDE (2B; 3B) DEL PISTON ALTERNATIVO (2; 3) ASIGNADO A LA MISMA. LAS PATAS (12, 13; 14, 15) DE CADA INDUCTOR (10, 11) SITUADOS EN LA LINEA CENTRAL ESTAN SEPARADAS (A) POR UN ESPACIO MAYOR QUE LA MITAD DE LA ANCHURA TOTAL (B) DE LOS PISTONES ALTERNATIVOS (2; 3). EL DISPOSITIVO DE LA INVENCION SE CARACTERIZA PORQUE LOS INDUCTORES (10; 11) ABARCAN LOS PISTONES ALTERNATIVOS (2, 3) DESDE PRACTICAMENTE LA MISMA DIRECCION, Y PORQUE LA ZONA EN LA QUE ES MAS ANCHA LA SEPARACION DE LAS PATILLAS INDUCTORAS (12, 13; 14) ESTA LIMITADA A LA SECCION (12C; 14C) DE LA PATILLA DEL INDUCTOR (12; 14) EN EL LADO SUPERPUESTO (5) QUE NO CRUZA, EN NINGUNA POSICION DE GIRO DEL EJE DE CONTROL (1), LA SECCION CORRESPONDIENTE (24C; 12C) DE LA PATILLA DEL INDUCTOR ASOCIADA A LA ZONA DE SUPERPOSICION (5) DE CUALQUIER OTRO INDUCTOR (11; 10).
