Abstract
A sprayhead especially suited for coupling to an extension hose for use in a pull-out kitchen faucet, the sprayhead including a selector subassembly for choosing between both spray and aerate modes, and a volume control built in to the sprayhead. The selector subassembly is engaged to a detent finger-button mounted on the housing that selectively diverts water flowing through an aerated flow path to an alternate spray flow path, thereby allowing manual selection between spray mode and aerate mode. The volume control is a slide switch on the housing and coupled to a rotary valve assembly for allowing the user to adjust the flow volume when in spray mode without affecting water volume in the aerate mode. When in aerate mode water is expelled from the sprayhead through an aerator output, and when in spray mode water is expelled through a series of nozzles oriented radially around the aerator output.
