Abstract

A chemical aspiration sprayer head includes a carrier channel (30) having an inlet (12), an outlet (14) through which the carrier fluid exits, and an expansion chamber (32) in between the inlet and outlet, a chemical supply channel in flow communication with the expansion chamber of the carrier channel through an aspiration opening (49), and a bleed line (60) extending from the chemical supply channel between the aspiration opening and the liquid chemical, the bleed line connecting the chemical supply channel in flow communication to ambient air. A control valve assembly (20) is seated in the sprayer head to simultaneously engage the carrier channel and the bleed line and with the carrier channel open, selectively open and close the bleed line to selectively permit ambient air to be drawn into the chemical supply channel in response to the aspiration flow produced by the flow of carrier fluid.
