Abstract

Foaming apparatus for foaming a water detergent mixture using compressed air comprises a housing having an elongated main bore extending therethrough. An upstream portion of the main bore is tapered in a generally downstream direction. A jet of water detergent mixture is delivered axially into the tapered portion of the main bore through a first orifice. Four second orifices extending transversely into the tapered portion deliver compressed air for mixing with and foaming the jet of water detergent mixture. Foamed water and detergent mixture is delivered through an outlet at the downstream end of the bore.
