Pressure expensive valve arrangement with a membrane valve assembly for the control of the fluid pressure in an abs - braking system of a vehicle with an integrated valve seat in a housing part in one piece.

摘要

The invention relates to a pressure expensive valve arrangement (7) for controlling the fluid pressure in an abs - brake system of a vehicle, in such a way that during a blocking tendency of the individual wheels (3a, 3b; 4a, 4b) of the vehicle, the braking pressure in the associated brake cylinders (6a to 6d) can be adapted to adaptively, wherein, in a housing (18) of the pressure expensive valve arrangement (7) at least two by means of spring elements (16a, 16b) loaded membrane (20a, 20b) having a diaphragm valves (14a, 14b) as well as at least one of an electronic control device (10) controllable electromagnetic control valve (15a, 15b) to the pilot control of the diaphragm valves (14a, 14b) are provided.The invention provides that at least one valve seat (30a, 30b) of the at least one electromagnetic control valve (15a, 15b) with a housing part (24) is constructed in one piece, which is driven by a plastic injection molding form - device is formed.
