Abstract

Un sistema perfeccionado de freno hidráulico para vehículos que comprende al menos un cilindro hidráulico conectado para funcionamiento a un varillaje de freno, y medios para controlar el suministro de fluido hidráulico a presión desde una fuente del mismo al cilindro hidráulico, caracterizado porque una primera válvula reductora de la presión que controla la presión del fluido suministrado al cilindro hidráulico en el lado de su émbolo que es opuesto al lado del émbolo cargado en la dirección de aplicación del freno por medio de un resorte de compresión, puede ser hecha funcionar para suministrar fluido hidráulico a presión a dicho cilindro en el lado del émbolo correspondiente al resorte, está ajustado para suministrar fluido hidráulico con un valor constante de la presión, que es más bajo que dicho valor máximo.
