Abstract

Mejoras en las unidades de control de la presión de frenado para los sistemas de freno hidráulico en los que los frenos de las ruedas traseras del vehículo son controlados por dos circuitos de freno independientes, comprendiendo dicha unidad de control una primera y una segunda válvula y un tabique divisorio móvil dispuesto entre los dos circuitos de freno, estando situada cada válvula entre una cámara de entrada conectada a una fuente de fluido de presión y una cámara de salida conectada a uno de los cilindros de rueda y siendo controlada por el tabique divisorio móvil, caracterizadas porque se provee un conducto de desviación (By-pass") que deriva la primera o la segunda válvula y porque en dicho conducto de desviación hay una válvula con respuesta a la deceleración.
