    摘要: In a gas mixing system for producing high-precision, continuous streams of mixed gas consisting of a plurality of individually metered gas components, with an individual gas line including a pressure reducing element and, if desired, a precision pressure regulator for each gas component, precision is further improved by providing that each gas line lead to a separate valve which is timed by electronic control means, the valves being connected at the input side via a jointly vented system of lines for pressure equalization, and communicating at the output side via a mixed gas line with a mixing chamber downstream thereof.
