Abstract
Abstract Venturi mixer means comprising a hollow cylindrical body with a rearward inlet port and a forward outlet port, and with replaceable orifice means being disposed rearwardly adjacent said inlet port. Venturi throat means having a throat area greater than the area of the orifice means are disposed forwardly of the orifice, with a plurality of radially disposed inlet openings being formed within said body between the orifice and the throat. The forward outlet port is preferably formed of a plurality of radially disposed openings for enhancing fluid agitation.
