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.
