Abstract
LA INVENCION CONSISTE EN UN SERVOMOTOR NEUMATICO DE FRENADO, QUE UTILIZA DOS FUENTES DE PRESION DE AIRE. COMPRENDE UNA CUBIERTA RIGIDA (3), DIVIDIDA POR UN TABIQUE MOVIL ESTANCO (4) EN POR LO MENOS DOS CAMARAS (3A,3B); EL TABIQUE MOVIL ES CAPAZ DE RESPONDER A LA DIFERENCIA DE PRESION EXISTENTE ENTRE LAS DOS CAMARAS, ARRASTRANDO ENTONCES UN PISTON NEUMATICO (5), QUE INCORPORA UNA VALVULA (7) ACCIONADA POR UNA VARILLA DE MANDO (10); EL INTERIOR (50) DEL PISTON ESTA SEPARADO DE LA SEGUNDA FUENTE POR UN FILTRO DEPURADOR (14). LA VARILLA DE MANDO (10) SE MUEVE DENTRO DE UN MANGUITO (16), QUE ATRAVIESA EL FILTRO DEPURADOR (14), Y PRESENTA UNA PARTE ENSANCHADA (100), QUE FORMA JUNTO CON UNO DE LOS EXTREMOS (162) DEL MANGUITO UNA VALVULA ADICIONAL, QUE PERMITE UNA ADMISION DE AIRE SUPLEMENTARIA Y DIRECTA EN EL PISTON (5) EN CASO DE APLICACION BRUSCA DE UNA FUERZA DE FRENADO IMPORTANTE.
