Abstract
A pressure control valve arrangement is provided for controlling the fluid pressure in an ABS brake system of a vehicle such 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 which are loaded by spring elements, and at least one electromagnetic control valve, which can be activated by an electronic control device for the pilot control of the diaphragm valves, are provided in a housing of the pressure control valve arrangement. At least one valve seat of the at least one electromagnetic control valve is formed in a unipartite fashion with a housing part which is formed by a plastic injection-molded blank.
