ABSTRACT:
A device for adding a second fluid to a first flowing fluid in a fixed ratio regardless of the flow rate of the first fluid. The device comprises a venturi section having an inlet, an outlet and a throat therebetween through which the first fluid flows, and a regulating section that modulates the pressure of the second fluid such that the amount of second fluid delivered to the venturi throat is a fixed proportion of the first fluid flowing through the venturi section regardless of the flow rate of the first fluid. The device has particular application for adding anti-icing fluid to liquid fuel during filling of aircraft fuel tanks.
