Abstract

A pressure control valve arrangement is described for controlling the fluid pressure in an ABS brake system of a vehicle in such a manner that, in the event of a tendency of individual wheels of the vehicle to lock, the brake pressure in associated brake cylinders can be adaptively adjusted, at least two diaphragm valves which have diaphragms loaded by spring elements, as well as at least one electromagnetic control valve which can be activated by an electronic control device for the pilot control of the diaphragm valves. Also described is a method for producing the pressure control valve arrangement.
