ABSTRACT:
In a preferred embodiment an improved faucet proportioner includes a plate for defining a first stream of water together with additional curtain streams of water adjacent the first stream. The first stream is directed into a venturi for pulling a second liquid, like detergent or sanitizer, while the curtain streams flow alongside outside of the venturi, but within the proportioner. The streams first contain any splash or splatter of the first stream at the venturi mouth, and secondly the streams enhance the venturi drawing action of the first stream upon joining the first stream as it flows out of the venturi discharge opening. The enhanced venturi action of the first stream effectively draws the second liquid into the first stream, yet the proportioner does not require any porous obstruction downstream of the venturi which might clog or retain detergent or sanitizer and release it when only pure water is desired. Methods are included.
