ABSTRACT:
A self-cleaning, water saver shower head which will provide a maximum flow rate without regard to water pressure and which may be adjusted from a no flow condition to a fine mist to a spray to a heavy pulsating rinse stream. The device uses a cavitation inducing orifice at the inlet to the head and a second cavitation inducing set of orifices upstream of the outlet with an elongated mixing chamber therebetween. A plunger is disposed in the outlet downstream of the second cavitation inducing orifices to direct the water exiting the device against a diffuser sleeve to define the spray. Rotation of a sleeve which defines the outlet and carries the diffuser causes axial displacement of the plunger within the outlet to provide the desired spray. In an embodiment of this invention, instead of a no flow condition, a drip condition will be produced by rotating the sleeve to cause axial displacement of the plunger until a knurled flange seats at the outlet thereof. Serrations on the flange permit a drip of water to pass therethrough so that when the shower head is in the drip position, a stream of water will not be permitted therethrough, but the water behind the shower head will not rise to the temperature of the hot water.
