Abstract
An apparatus for pulsing water flowing to a shower head includes a housing with a chamber, first and second water inlets to the chamber and a water outlet. The second inlet and the outlet are located through a wall of the housing at one end of the chamber. A valve has a plate with a plurality of apertures. The valve disposed within the chamber so that water flowing through the first inlet urges the valve into close proximity to the housing wall where rotational movement of the valve alternately opens and closes the water outlet. That action creates a pulsed flow of water through the outlet. Water flowing into the chamber through the second inlet moves the valve plate away from the housing wall permitting water to flow continuously from the second inlet into the outlet without being pulsed. A mechanism is coupled to the valve to produce the rotational movement.
