Abstract
A device for injecting additive fluids into a stream of a primary fluid as it passes through a common central bore is characterized by a series of specially formed layers each having a particular fluid flow pattern formed therein. The layers are registered one above the other and sandwiched together to form an integral unit in which there are separate fluid flow channels for each of a desired number of additive fluids. Each channel has an inlet for receiving fluid from an associated pressurized source and a plurality of outlets terminating in angularly spaced relationship around an interior perimeter surface of the common bore. A selection mechanism provides for choosing a desired additive fluid for injection into the primary fluid in a manner coordinated with the flow of the primary fluid through the common bore.
