Abstract

Dispositivo de acumulador para mecanismo de servofreno, pudiendo éste ser accionado por una fuente de fluido obtenida a partir de una bomba que suministra presiones variables entre un valor mínimo y un valor máximo, incluyendo el servofreno un carter con una cavidad central que se extiende a través de él, un elemento de entrada que se extiende en la cavidad, un elemento de salida que se extiende a partir de la cavidad, un dispositivo de émbolo entre los elementos de entrada y de salida para desplazar el elemento de salida en respuesta al movimiento de elemento de entrada y que incluye una cámara de accionamiento en el interior de la cavidad, unos dispositivos de válvula de entrada y de salida que pueden funcionar en respuesta al movimiento del elemento de entrada para controlar la comunicación del fluido entre dicha cámara de accionamiento y dicha fuente; estando dicho freno caracterizado porque incluye una cámara de acumulador asociada con el carter; una válvula de alivio interpuesta entreuna conexión de fluido con la fuente y la cámara de acumulador, proporcionando la válvula de alivio en su primera posición la comunicación del fluido entre la cámara de acumulador y dichas válvulas de entrada y salida mientras que en su segunda posición impide dicha comunicación del fluido; y un dispositivo de válvula de retención asociado con la válvula de alivio y que puede funcionar para facilitar e impedir efectivamente la comunicación del fluido entre la conexión y la cámara de acumulador cuando el fluido en la conexión tiene una presión superior y una presión inferior a dicho valor mínimo.
