Pulsating water jet massage shower head construction
First Claim
1. A massage shower head comprising a housing having a water chamber therein, a mechanism in said water chamber for producing pulsating water jets including a nozzle plate enclosing said water chamber, a valve rotor which is mounted in said water chamber for free rotation and axial play directly above said nozzle plate, said nozzle plate having a bottom with an interior surface, a plurality of nozzle bore portions extending inwardly toward said valve rotor from said interior surface of said nozzle plate bottom each having at least one jet forming nozzle bore therethrough and through said bottom, said valve rotor being provided with at least one radial wall element as well as with a segmental closing disk portion, water conveying channel means connected into said water chamber directed so as to produce a rotary water motion in said water chamber in the space accommodating said rotor, said water chamber having a pressure cavity between the plane of rotation of said closing disk portion of said valve rotor and said nozzle plate which is open toward said nozzle plate, said jet forming nozzle bore projecting into approximately the plane of rotation of said closing disk, whereby a water cushion is formed between said rotor and said nozzle bore portions by water flowing into said pressure cavity.

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.

- 14. A pulsating water jet massage shower head, comprising a shower head housing having an interior chamber opened at one end, a nozzle member closing the one end of said housing chamber and having a bottom with an interior and exterior surface, said bottom including a plurality of nozzle bore portions extending inwardly from said interior surface with at least one nozzle bore through each of said nozzle bore portions forming spray nozzle discharges through said bottom, a cover member in said housing member spaced inwardly from said nozzle bore portions, a valve rotor rotatably positioned between said cover member and said nozzle bore portions and being free for axial movement therebetween and having a plurality of radial wall portions and a closing disk portion, a portion of said housing chamber between said valve rotor and said nozzle bottom defining a pressure cavity, water conveying channel means defined in said housing for conveying a water stream upstream of said cover member into said pressure cavity, said cover member and the manner in which the water is conveyed by said conveying channel producing pulsating water jets through said nozzle bores, said nozzle bores through said nozzle bore portion of said bottom extending up to approximately the plane of rotation of said valve rotor closing disk portion, said valve rotor being floatable in rotary motion in said water stream whereby a water cushion is formed by the water stream between said valve rotor and said nozzle member.
