Abstract

Válvula de control de la presión en los frenos hidráulicos de vehículos, en los que hay un primer circuito de freno correspondiente a las ruedas delanteras y un segundo circuito de freno que corresponde a las ruedas traseras, en el que los cilindros de freno receptores del primer circuito de freno están conectados a una primera cámara de presión de un cilindro maestro y los cilindros de freno receptores del segundo circuito de freno están conectados a una cámara de salida de un regulador, y en el que una segunda cámara de presión del cilindro maestro está conectada a una cámara de entrada de la válvula de control de la presión, habiendo en el conducto de fluido a presión, entre la cámara de entrada y la de salida, una válvula que tiene un obturador sobre el que actúa un pistón de control que está precargado pr un muelle y que tiene una superficie sometida a la presión del primer circuito de freno, caracterizándose la válvula de control objeto de este invento porque tiene un pistón anular (24) deslizable dentro de unos límites el cual tiene un orificio (25) en el que hay un pistón de control (27), teniendo dicho pistón anular (24) una de sus superficies anulares sometidas ala presión del primer circuito de freno y su otra superficie anular sometida a la presión regulada del segundo circuito de freno, y porque el extremo (27) del pistón de control (27) del lado de la válvula se apoya contra el pistón anular (24) en el sentido de acercamiento al muelle (37).
