ABSTRACT:
A shower head is provided which can, alternatively, provide a fine, steady stream of shower water or a coarser, pulsating stream of shower water to produce a massaging effect. All of the water stream is, initially, pulsed, but the pulsation is removed when a steady stream is desired.
The incoming water enters the spinner of a Hero's engine axially; it causes rotation of the engine spinner as it leaves the tangentially directed exit spouts of the engine. The water then enters a chamber having a circular outlet cover plate carrying small peripheral holes and larger, more centrally located holes inside the periphery.
A rotatable dial plate is positioned between the circular outer cover plate and the plenum chamber. This plate has holes in it which can be aligned with the large inner massaging holes, with channels leading to the outer peripheral holes, or at a position in between. The position of the dial plate is controlled by an associated control arm. Thus, the position of the holes used differs between the type of spray desired, i.e., steady or massaging.
A cutting vane rotates with the engine spinner and "chops" the water before it passes through the holes in the dial plate. If the water then goes out to larger holes, it is pulsing and so gives a massage effect. If it passes through the channels to the peripheral holes, there is an averaging effect, and the pulsation is substantially removed by the time the water leaves the peripheral holes.
The control arm is held in position by a spring-pressed washer which allows it to be removed slightly from the cover to have a U-shaped brush slipped between the cover and the control arm for use in washing.
