ABSTRACT:
Two gases are fed to a mixing valve having two outlets, and the proportions of the two gases, at each of the said outlets, is varied inversely in accordance with the position of a moveable portion of the mixing valve. If the back pressure at the two outlets is equal, and if the supply pressure of the two gases is equal, the proportioning of the two gases will be accurately determined by the adjustment of the valve. Thus, in an automatically controlled system requiring the presence of gases in time-variable proportions, proper proportioning can be achieved by the use of a mechanical valve, without the necessity of a gas testing analyzer and a feedback system for controlling an ordinary mixture proportioning valve.
