Abstract
Abstract A shower head having a series of circumferentially spaced holes for delivering water to a supply chamber closed by a directional control valve. The control valve has a series of angularly arranged holes for producing water jets directed to impinge upon a grooved surface of a diffuser. The diffuser is mounted on a spindle which passes through the control valve into the body of the shower head. The diffuser has a diameter selected to define a narrow gap within the shower head from where a water mixture is discharged. Emollients, oils, soap or other scented materials are introduced by an injector through the shower head into a mixing chamber between the control valve and the rotary diffuser. Parallel grooves at the discharge end of the shower head deliver the water mixture in the form of shower producing water droplets.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
A shower head apparatus of the type for use in combination with means for delivering a controlled water supply, said apparatus comprising: a shower head including tubular-shaped walls joined with an end wall to define a hollow internal chamber, means including a directional control valve in said end wall for discharging at least one stream of water into said internal chamber, diffuser means having a generally smooth wall surface arranged in said chamber to form a water discharge gap with said tubular-shaped walls, said diffuser means including impeller surfaces defined on a generally conically shaped surface thereof extending toward said end wall. a spindle rotatably supporting said diffuser for impinging contact with said stream of water at a spaced relation from said end wall, and reservoir means communicating with said chamber at a location between said diffuser and said end wall.
Claim 2
Dependent Claim
