Abstract

Conjunto de cilindro principal para sistema de frenos de vehículo dotado de dos circuitos de presión, que incluye un cilindro principal con dos cámaras de presión separadas asociadas con pistones respectivos, estando una cámara dispuesta para su conexión con uno de los circuitos de presión, y un dispositivo de válvula de control, que tiene un orificio de entrada previsto para ser conectado con la otra de dichas cámaras y un orificio de salida previsto para ser conectado con otro de los circuitos de presión, una válvula normalmente abierta para controlar la comunicación entre la entrada y la salida, y un conjunto de pistón auxiliar que puede desplazarse para abrir y cerrar la válvula, caracterizado porque dicho dispositivo de válvula (2) está sujeto en el cilindro principal (1), el conjunto de pistón auxiliar (16), tiene dos porciones (17,20; 31, 32; 51, 52), estando sometida una porción (17; 31; 52) a la presión del orificio de salida (9) del dispositivo de válvula y estando la otra porción(20; 32; 51) a la presión de dicha otra cámara (6) del cilindro principal (1), y pudiendo entrar en contacto dicha otra porción (20; 32; 51) con el pistón adyacente (4) del cilindro principal, en caso de fallo de la presión en dicho primer circuito de presión, para desplazar el conjunto de pistón auxiliar (16) hasta una posición en la cual la válvula (12, 14) se mantiene abierta.
