Abstract

Mejoras en los multiplicadores hidráulicos de frenado constituidas por un multiplicador hidráulico en el cual hay un pistón que por el lado más próximo al pedal limita una cámara de multiplicador y en el que además existe un husillo de válvula, que puede deslizarse movido por el pedal, que alternativamente conecta a dicha cámara de multiplicador con una fuente del fluido transmisor de la presión o con un depósito de retorno no presurizado; en el que la fuente del fluído transmisor de la presión es una corriente de fluido impelida por una bomba, la cual puede ser estrangulada por una válvula de control de paso, y en el que el pistón del multiplicador puede activar, por intermedio de un vástago de empuje, a un cilindro patrón estático, caracterizado porque un elemento móvil de válvula (19), de la válvula de control de paso del fluido (2), es dispuesto alrededor del vástago de empuje (16) y concéntrico al mismo, haciendo que dicho vástago de empuje (16) le desplace mecánicamente hacia el cilindro patrón (3) para así obtener la estrangulación de la corriente impulsada por la bomba.
