Abstract

UN DISPOSITIVO DETECTOR DE PRESION DIFERENCIAL. ESTA CONSTITUIDO POR UN INTERRRUPTOR DE ALARMA DE FRENO (14) EN EL QUE EL PISTON O CARRETE (35) SE DESPLAZA AXIALMENTE EN UN MOVIMIENTO ALTERNATIVO DURANTE CADA CICLO DE APLICACION DEL FRENO, DE UN AUMENTO DE PRESION HASTA UN MAXIMO Y UNA DISMINUCION DE NUEVO, YA SEA HACIA CERO O CUALQUIER PRESION RESIDUAL QUE PERMANECE EN EL SISTEMA. LOS MIEMBROS DE SELLADO QUE AISLAN LOS DOS CIRCUITOS HIDRAULICOS (11, 12) ENTRE SI, Y DEL CONDUCTO DEVENTILACION HACIA LA ATMOSFERA, SE MUEVEN A LO LARGO DE CADA UNA DE LAS SUPERFICIES DE SELLADO, PARA ASEGURAR QUE PERMANEZCAN LIMPIEAS.
