Abstract
A hydraulic automotive brake system with wheel slip control, includes a pressure medium source, to which a main pressure line is connected, which leads to a wheel brake, first and second pressure relief line segments connected to the wheel brake and leading to a supply reservoir, and having a pressure modulation valve arranged in it that either separates the supply reservoir from the wheel brake or connects it to the wheel brake, as well as a control orifice valve that is arranged in the main pressure line upstream of the first pressure relief line segment, actuated by changes in the hydraulic pressure. The brake system features a pressure chamber that actuates the control orifice valve and is provided with check valves, of which one of the check valves separates the pressure chamber from a pressure medium branch of the main pressure line arranged upstream of a control orifice, the other check valve connects the pressure chamber to the connection of the pressure relief line segment to the wheel brake, and whereby a final control element is guided in a sealed manner in the first pressure chamber and is exclusively exposed to pressure from the pressure medium source in the one direction of actuation of the control orifice valve, and in the other direction of actuation is exposed to the pressure change in the pressure chamber.
