<p>A brake pressure control apparatus for automotive vehicles with an anti-locking control system is presented. It is comprised of a master cylinder, of one or of a plurality of wheel cylinders for wheel brakes, of a pressure modulator for the modulation of the hydraulic pressure in the wheel cylinders of the wheel brakes during a brake pressure control modus, of at least one motor-driven pump for the generation of a hydraulic pressure, of an electronic controller. The outlet valve associated with a wheel cylinder is furnished with a closing element (5) which is connected to the closing element (6) of the inlet valve through a captivating apparatus which is configurated and positioned in such a manner that in its closing position the said closing element (5) of said outlet valve opens the said closing element (6) of said inlet valve and in its open position it closes said closing element of the inlet valve. The inlet valve and the outlet valve have an electronic coupling comprised of an inlet solenoid valve and of an orifice. In the control modus, said inlet solenoid valve will be switched and be brought into its closed position. Under the effect of the master cylinder pressure and/or the pump pressure, said valve is, now, given the function of a non-return valve, which remains in its closed position even while the actuating solenoid is in the de-energized condition. In this situation, pressure agent is restrictedly conveyed through the orifice to the wheel cylinder.</p> |
