Abstract
A pulsating water jet massage shower head comprises a shower head housing which has an interior chamber which opens outwardly. A nozzle member comprising a flat plate nozzle portion in a cylindrical fitted portion is fitted into the chamber of the housing and it is provided with a plurality of nozzle bores which extend through hollow cylindrical pin portions which extend upwardly from the interior surface of the plate portion. A cover member is arranged in the housing chamber spaced inwardly from the nozzle member and it has a segmental closing disk portion which acts to deflect water which is delivered through connecting conduits in the housing so as to cause rotation of a valve rotor positioned between the cover member and the nozzle member. The deflection and the rotation of the valve rotor produce rotating water jets through the nozzle bores. The valve rotor is mounted so that it floats between the cover member and the nozzle member and a pressure chamber is defined between the bottom of the nozzle plate and the valve member.
