1: A valve arrangement for brake control of a vehicle braking system which is operated using pressure medium, the valve arrangement comprising:
a relay valve arranged in a housing; and a solenoid valve configured for controlling the relay valve; wherein the relay valve has an axially displaceable relay valve piston with a first annular sealing seat configured to be acted on with a control pressure which is directed into a control pressure chamber and which can be adjusted by the solenoid valve having an axially displaceable plate valve having a radial sealing face, and having an insert secured to the housing which separates an operating chamber from a pressure chamber and which has a second annular sealing seat which is arranged coaxially relative to the first annular sealing seat of the relay valve piston, wherein the first and second annular sealing seats cooperate simultaneously or alternately with the radial sealing face of the plate valve in such a manner that, when control pressure is applied, a storage pressure from the pressure chamber reaches the operating chamber at the side of the relay valve piston which is remote from the control pressure chamber, and, when the control pressure is relieved, the pressure in the operating chamber is returned to a pressure medium container or is vented to the environment, wherein the housing has at least one cylindrical receiving member which is closed at one side and which forms the control pressure chamber, the operating chamber, and the pressure chamber for arrangement of the relay valve piston, the insert which is secured to the housing and a carrier element for the plate valve which can be axially introduced into the receiving member in the sequence mentioned and fixed therein. |
