Abstract
Una unidad de control de la presión mejorada para el sistema de freno hidráulico de los vehículos, la cual incluye una válvula reductora de la presión y una válvula limitadora de la presión dispuesta concéntricamente con ella, con un pistón intermedio interpuesto entre la válvula reductora de la presión y la válvula limitadora de la presión el cual es accionado por la presión de salida, caracterizada porque, por medio de un tope solidario con el cuerpo de la unidad de control se limita el desplazamiento del pistón intermedio en el sentido de acercamiento a la válvula reductora de la presión y porque el pistón intermedio tiene una cámara axial en la que hay un pistón auxiliar que es igualmente accionado por la presión de salida y el cual se puede apoyar, por uno de sus lados, en el pistón escalonado o en el miembro de cierre de la válvula reductora de la presión.
