Abstract

Amplificador de frenos que tiene un alojamiento (30) con al menos una salida (44) que comunica con un freno (18), un pistón (38) dispuesto movible dentro del alojamiento (30) entre una cámara de presión (42) y una cámara de trabajo (76), un grupo de entrada (72) para controlar la transmisión de presión de uido a la cámara de trabajo (76) y en el que la presión de fluido solicita el pistón (38) para desplazarlo desde una posición de reposo hasta una posición de frenado, un grupo valvular (80) accionable en respuesta al movimiento del grupo de entrada (72), una entrada (28) formada por el alojamiento (30) para transmitir presión de uido al grupo valvular (80), un alojamiento de válvula (79) dispuesto entre el pistón (38) y el grupo de entrada (72) y el grupo valvular (80) dispuesto dentro del alojamiento de válvula (79), incluyendo este último una prolongación (81) que recibe el pistón (38) deslizante en su interior, caracterizado por el hecho de que el amplificador de frenos (12) comprende medios elásticos (89) dispuestos entre el pistón (38) y el alojamiento de válvula (79) para solicitar el pistón (38) en el sentido de alejarlo de este alojamiento (79).
