Abstract

1.Una disposición de frenos hidráulicos de doble circuito, con control de deslizamiento, en particular para vehículos automóviles, en la que los frenos de rueda están conectados, a través de unas válvulas de disposiciones múltiples electromagnéticamente accionadas, a unos circuitos de freno que están hidráulicamente aislados entre sí, en el que los circuitos de freno son presurizables por una parte por un cilindro maestro en tándem y por otra pueden ser conectados a una bomba conjunto de dobles circuito adaptada para ser accionada por un motor eléctrico, caracterizado porque las dos salidas de la bomba conjunto (76,77) están conectadas a unas válvulas de freno (43, 44) normalmente cerradas que están gobernadas por la presión del cilindro maestro y porque en las conexiones entre el cilindro maestro en tándem (1) y los frenos de rueda (26, 27, 41, 42) hay insertadas unas válvulas separadoras (11, 12) que están adaptadas para ser cerradas por la presión de salida de las válvulas de freno (43,44). 2.Una disposición de frenos hidráulicos de acuerdo con la reivindicación 1, caracterizada porque una de las válvulas de freno (43, 44) gobierna el suministro de la presión a los frenos de rueda (26, 27) del eje trasero mientras que la otra válvula gobierna el suministro de la presión a los frenos de rueda (26, 27) del eje trasero mientras que la otra válvula gobierna el suministro de la presión a los frenos de rueda (41, 42) del eje delantero. 3.Una disposición de frenos hidráulicos de acuerdo con la reivindicación 1, caracterizada porque "aguas arriba" del cilindro maestro en tándem (1) hay conectados un servofreno de vacío (2). 4.Una disposición de frenos hidráulicos de acuerdo con la reivindicación 1, caracterizada porque las válvulas de freno (43, 44) y las válvulas separadoras (11, 12) están diseñadas como válvulas de asiento. 5.Una disposición de frenos hidráulicos de acuerdo con la reivindicación 1, caracterizada porque cada una de las válvulas de freno (43, 44) contiene un pistón de válvula (56,65) que tiene un orificio axial (56, 65) es desplazable con estanqueidad por el interior de una cámara no presurizada (58, 67) mientras que la otra cara frontal del pistón de válvula (56, 65) tiene la forma de un obturador de válvula (64, 54), y está precargado hacia un asiento de válvula (53,68), porque una cámara anular que está conectada a una salida de la bomba está adaptada para ser cerrada por dicho obturador de válvula (54, 64), y porque concéntrico con el pistón de válvula (56, 65) hay un pistón (48, 60) que está adaptado para ser accionado por la presión del cilindro maestro (1) y con el que el orificio axial (55, 66) del pistón de válvula (56, 65) está adaptado para ser cerrado y el obturador de válvula (64, 54) que hay formado en el pistón de válvula estando adaptado para entonces separarse de su asiento (53, 68). 6.Una disposición de frenos hidráulicos de acuerdo con las reivindicaciones 4 y 5, caracterizada porque entre los pistones de válvula (56, 65) y los pistones de las válvulas de freno (43, 44) hay unas cámaras (50, 62) normalmente no presurizadas y cada una de las cuales están en comunicación hidráulica con un pistón de cierre (14, 30) de una válvula separadora (11, 12). 7.Una disposición de frenos hidráulicos de doble circuito.
