## Abstract

A shower head comprising a first part adapted to be connected to a source of water and a second part mounted on the first part for pivotal movement about a transverse axis. The second part has an opening adapted to be aligned with an opening in the first part. The opening in the second part has a venturi-shaped portion. A third part is telescoped over and surrounds the second part and defines a pressure chamber into which water is directed from the venturi. The third part has a plurality of openings therein and a passage extends from the restricted portion of the venturi to the exterior for attachment to a fluid dispenser.
