摘要
A gas mixing device comprises a plurality of gas lines for the conveyance of the separate gases to be mixed, each of which has a pressure regulator with a pressure control. A common gas mixture line is connected to each of the gas lines downstream of the pressure controls therein and a constant admission pressure regulator is provided in the mixture line. Control pressure is provided from a control pressure source which, for example, may be at the tapping of the gas mixture line. The control pressure is connected to each of the pressure controls for the pressure regulators and the gas lines and this control pressure is regulated by control means which may be in response to the pressure in each of the individual gas lines or in response to the pressure in the common gas mixture line downstream of the constant admission pressure regulator means.
