Abstract
Mejoras introducidas en el objeto de la Patente principal nº 471495, por dispositivo de frenado asistido, según las cuales dicho dispositivo de frenado comprende un pistón de mando montado deslizante en un cilindro de mando, un gato que tiene un pistón unido al pistón de mando por medios de interconexión, una fuente de presión hidráulica de asistencia, y un distribuidor adaptado para alimentar al gato con presión hidráulica de asistencia a partir de la citada fuente, y mandado en respuesta a un accionamiento de medios pilotos que llevan un pedal, en el que el citado pedal está dispuesto en un extremo de una palanca, que está directamente montada, por una articulación , sobre los citados medios de interconexión, y cuyo otro extremo actúa sobre el citado distribuidor, y se caracteriza porque un medio de tope, que forma apoyo para la palanca de pedal, está previsto más cerca de la articulación de la citada palanca sobre los medios de interconexión que el extremo de la citada palanca que actúasobre el distribuidor de tal modo que, en caso de fallo de la asistencia, quede asegurada una suplencia manual por el pedal, por apoyo de la citada palanca sobre el citado medio de tope.
