ABSTRACT:
An apparatus for combining fluids having a piston assembly which controls both the flow rate and the mixture ratio. The piston assembly is carried in a housing having two inlet ports and an outlet port or mixing chamber. The housing and piston assembly also define first and second piston chambers. A first passageway permits the communication of the dominate gas port and the one piston chamber and a second passageway similarly permits the communication of the mixing chamber and the another piston chamber. The relative pressures in the first and second piston chambers influences the axial position of the piston which controls flow rate. Rotation of the piston controls mixture ratio.
