Pressure control valve arrangement having covers that are produced as a completely integral part with transverse channels by primary shaping

The invention relates to a pressure control valve arrangement (7) for controlling the fluid pressure in an ABS brake system of a vehicle in such a way that, in the event of a tendency of individual wheels of the vehicle to lock, the brake pressure in at least one associated brake cylinder (6) can be adaptively adjusted, at least one diaphragm valve (14a, 14b) being accommodated in a housing (21) of the pressure control valve arrangement (7). Said diaphragm valve has at least one diaphragm (25a, 25b) as the valve body, which diaphragm can be acted upon by introducing a pressure medium into a control chamber (26a, 26b) that is covered by respective covers (27a, 27b) on the exterior of the housing in such a way that the control chamber (26a, 26b) is formed between the diaphragm (25a, 25b) and the cover (27a, 27b).; The cover (27a, 27b) is produced by primary shaping such as injection molding and has blind holes (29a, 29b) which extend in the cover (27a, 27b) substantially at a right angle to the plane of the cov
