Abstract
LA REJILLA ADICIONAL ESTA DESPROVISTA DE CINTURON Y TIENE AL MENOS DOS JUEGOS DE PLAQUITAS (28, 30) ENTRECRUZADAS Y FIJADAS UNAS A OTRAS EN SU CRUZAMIENTO, DOTADAS DE ALETAS (32) DE AGITACION DEL REFRIGERANTE, QUE DELIMITAN CELULAS DESTINADAS A SER ATRAVESADAS UNAS POR TUBOS GUIAS Y OTRAS POR LAPICES DE COMBUSTIBLE. CADA PLAQUITA ESTA PROVISTA, EN CADA CARA DE CELULAS INTERNAS QUE RECIBEN UN LAPIZ DE CAPAS (38) CUYO SALIENTE ES SUFICIENTEMENTE PEQUEÑO PARA DEJAR UNA HOLGURA RADIAL A LOS LAPICES QUE ATRAVIESAN LA CELULA Y ESTA PROPORCIONADA AL SALIENTE DE LAS ALETAS DE MANERA QUE EL LAPIZ SE PONGA EN CONTACTO CON LAS CAPAS SIN ALCANZAR LAS ALETAS EN CASO DE VIBRACION EN FLEXION, SIENDO TAL LA LONGITUD DE LAS PLAQUITAS QUE LA DIMENSION EN PLANO DE LA REJILLA ADICIONAL ES INFERIOR AL DEL POLIGONO QUE CONSTITUYE LA ENVOLTURA VIRTUAL DE LOS LAPICES.
