Abstract: A fluid injection device includes a housing and a valve stem. The housing includes an inlet arm having an inlet orifice for receiving a feeder fluid. An outlet arm has an outlet orifice to discharge a mixed fluid. A venturi tube is between the inlet and outlet arms. The inlet arm, veturi tube and outlet arm define a nonlinear fluid pathway where the venturi tube redefines a portion of the nonlinear fluid pathway as a constricted fluid pathway. A diverter port is used to divert a portion of the feeder fluid from the inlet arm into the container and an injection port is used to receive product from the container. A valve arm is collinearly aligned with the venturi tube and the valve stem is positioned within the valve arm and adjusts the volume of the constricted fluid pathway.
