Abstract:
Gas pressure regulator, comprising a gas-tight casing (1) that houses an inlet-side chamber (19) and an outlet-side chamber (22) connected with each other by a passage, where such passage forms a valve seat (24) to accommodate a valve disk (25) that is guided through a rod (28) and can be moved in axial direction inside the casing (1), and where said rod (28) is connected to a pressure diaphragm (7) at its far end seen from the valve disk (25), whereby the pressure diaphragm (7) is pressurized by the pressure built up in the outlet-side chamber (22) and pushed into closing direction, whereat the adjusting spring (12) pushes said pressure diaphragm (7) into opening direction of the valve disk (25), characterized in that the inlet-side chamber (19) and the outlet-side chamber (22) are connected to each other by one or more separate openings (34) with each of such opening forming a seat (35) for a closing body (33) that is individually assigned to said opening and guided in axial direction to its seat (35), whereat each such closing body (33) is connected to the armature (31) of an electro-magnetic drive assigned to it.
