Abstract

Válvula de control de presión de frenos hidráulicos que incluye un cárter provisto de un primer orificio entrada y de un orificio de salida conectado con un primer circuito de presión y un segundo orificio de entrada conectado preferentemente con un segundo circuito de presión, un pistón de válvula dispuesto de manera deslizante en el cárter y que presenta un conducto que lo atraviesa y que conecta el primer orificio de entrada con el orificio de salida, un pistón de accionamiento que recibe la presión a partir del segundo orificio de entrada y que está en contacto con el pistón de válvula por medio de un vástago para empujar el pistón de válvula por medio de un vástago para empujar el pistón de válvula hacia el primer orificio de entrada, un asiento de válvula formado en una extremidad del conducto que se abre hacia el primer orificio de entrada, un cuerpo de válvula que coopera con el asiento de válvula y que está dispuesto de manera deslizante en un agujero formado en el cárter, abriéndose una extremidad de dicho agujero hacia la atmósfera mientras que la otra extremidad está sometida a la presión que reina en el primer orificio de entrada y un muelle que empuja el cuerpo de la válvula hacia el asiento de la válvula.
