Abstract

A hand held water outlet head includes a piston 10 carrying a valve disk 8 movable between two seats 6,7 for selectively directing an incoming water flow to either an aerator nozzle 17 via ducts 41,44,46, or to shower outlets 47 concentrically surrounding the nozzle via ducts 42,43.The piston/valve disk position is controlled by the thumb depression of a diaphragm 34 overlying a rocker arm 29, whose one end 32 is coupled to the piston and whose other end 31 may be latched by a slider 21. Incoming water pressure holds the disk in the shower position against the force of a spring 11, which returns the disk to the nozzle position when the water is turned off, unless the rocker arm is latched by the slider.
