Abstract: A showerhead including an inlet end and an outlet end. The inlet end of the showerhead body forms a spiral chamber which produces a rotating current of water. An inner disc having a series of ports therethrough is positioned immediately adjacent to an outer disc which also has a series of ports therethrough. A spinner, on the inlet end of the inner disc, rotatably driven by the rotating current of water, has open and closed portions which pass in sequence across certain of inner disc ports producing a pulsating water stream therethrough. The outer disc is rotationally adjustable relative to the inner disc. The ports of both discs are arranged in concentric rings such that as the outer disc is rotated relative to the inner disc, varying throughpaths are achieved as the outer disc ports align with the inner disc ports. Four spray modes are achieved: (1) a variable regular spray, (2) combination pulsating and regular spray, (3) variable pulsating spray, and (4) variable pulsating misting spray.

Abstract: A spray head including a handle disk having an exposed front wall and manually engageable peripheral portion the wall having a set of jet nozzles arranged in a circle, the perforations having common communication with a set of fine spray nozzles; the handle disk being mounted for limited arcuate movement with respect to a housing having a mating perforated wall for exposing the jet nozzles or the perforations communicating with the spray nozzles. The interior of the housing forms a chamber in which water is caused to rotate and drive a rotor having at least one opening which passes intermittently across the jet nozzles or perforations depending on the position of the handle disk. When the jet spray nozzles are activated the effect of the rotor and its slot is to cause the jet nozzles to produce pulsating jets. When the fine spray nozzles are activated, the water entering the perforations is diffused to produce essentially constant flow through the fine spray nozzles.
