A pulsating shower head that employs a rotor for effecting the discharge of a variable pulsating spray, a variable continuous spray, or a combination of both comprising an upper body housing, a rotatable lower body housing, a stationary stem housing affixed to the upper body housing, an O-ring retainer affixed to the stem housing, and a stem－rotor housing assembly that moves axially when the lower body housing is rotated. An O-ring affixed to the stem acts in conjunction with the O-ring retainer to open and close a water channel leading to a pulse chamber. At the same time, O-rings affixed to the stem housing act in conjunction with the rotor housing to open and close a water channel leading to a continuous spray chamber. Rotation of the lower body housing results in either a continuous spray, pulse spray, or combination continuous and pulse spray. The shower head may be incorporated into either a wall mounted unit or a hand held unit.

A pulsating shower head comprising: an upper body housing having a cup-shaped outer wall, a downstream-extending inner wall and a center stem; a lower body housing having an outer wall abutting the upper body housing outer wall and a multi-tiered inner wall, said multi-tiered inner wall having an up
A pulsating shower head comprising: an upper body housing having a cup-shaped outer wall, a downstream-extending inner wall and a center stem; a lower body housing having an outer wall abutting the upper body housing outer wall and a multi-tiered inner wall, said multi-tiered inner wall having an upstream section; a stem housing configured to fit within the upstream section and affixed to the upper body housing center stem and having an upstream end and a downstream end, said stem housing being generally cylindrical in shape and having near its upstream end threads disposed on the inside of the stem housing for receiving a hollow stem, said stem housing having two circumferentially outwardly facing grooves for holding O-rings, said O-rings providing a sliding watertight seal between the stem housing and a rotor housing, a plurality of apertures interposed between the two grooves for directing water flow, and means for retaining an O-ring retainer near the stem housing downstream end; the hollow stem having a threaded upstream section, a middle section, and a downstream section, the hollow stem being threadably connected at the hollow stem upstream section to the stem housing, the hollow stem having a plurality of apertures for directing water flow near the hollow stem upstream section and a circumferentially outwardly facing groove disposed about its middle section for holding an O-ring, said middle section O-ring providing a sliding watertight seal between the hollow stem and said O-ring retainer; the rotor housing held in fixed relation to the hollow stem and having a transverse wall and upstream and downstream sections extending therefrom, the rotor housing having a plurality of tangentially directed flow channels disposed in the transverse wall which direct jets of water downstream thereof into a rotor chamber at a rotor driving velocity, the rotor housing being axially translatable with respect to the stem housing; a pulse plate having a transverse wall with a set of pulse spray apertures therethrough and a substantially cylindrical wall extending upstream from the transverse wall, said cylindrical wall abutting the stem downstream section, said pulse plate transverse wall abutting the rotor housing downstream section, said pulse plate transverse and cylindrical walls defining said rotor chamber; a rotor rotatably mounted in said rotor chamber; a spray seal retainer affixed to the lower body housing; and a spray seal interposed between the spray seal retainer and lower body housing, the spray seal and the rotor housing downstream section defining a set of continuous spray apertures; wherein rotation of the lower body housing causes the stem to translate axially on the threaded inner wall of the stem housing, causing the selective discharge of either a pulsed spray through the pulse spray apertures, or a continuous spray through the continuous spray apertures, or a combination of both pulse spray and jet spray.
