Abstract
An apparatus is provided for mixing two or more fluids together in a desired ratio. The mixing apparatus includes primary and secondary conduits, one extending from a source of a first fluid and the other extending from a source of a second fluid, and a diversion conduit extending between the primary and secondary conduits and through which a selected amount of the first fluid will be diverted from the primary conduit. An eductor, position in the primary conduit, is connected to the secondary conduit so that the second fluid will be drawn from a source and will intermix with a selected flow of first fluid through the diversion conduit prior to entering the eductor. Upon entering the eductor the premixed fluids combine with the first fluid flowing through the eductor from the primary conduit. The amount of premixed fluids which combines with the first fluid in the eductor is dependent upon the flow of first fluid in the primary conduit through the eductor.
