Abstract

PARA ACTUAR DE FORMA RECIPROCA VARIAS VALVULA (5,6) SIMULTANEAMENTE DE UN MOTOR DE COMBUSTION INTERNA POR MEDIO DE UNA LEVA (18) Y UTILIZANDO LOS EMPUJADORES (7,8) DISPONIBLES COMERCIALMENTE Y LOS RESORTES (20,21) DE VALVULA, LA INVENCION PROPONE QUE UNA BARRA (14) TRANSVERSAL SE COLOQUE CRUZANDO EL FONDO DE LOS EMPUJADORES (7,8), ACTUANDO LA LEVA (18) DIRECTAMENTE, O POR MEDIO DE UN BALANCIN, SOBRE LA BARRA TRANSVERSAL ENTRE LOS EJES DE LAS VALVULAS (5,6). LA BARRA (14) TRANSVERSAL ESTA ASEGURADA EN SU LUGAR POR MEDIO DE UN ESPARRAGO (16) QUE SE PROYECTA ENTRE LOS EMPUJADORES (7,8).
