ABSTRACT:
A pulsating spray head is provided for attachment to a source of fluid under pressure, e.g. water, which is of simple construction and provides for effective pulsations. The head comprises a housing in which is mounted a body portion which is closed off by a primary plate having a plurality of rows of radially extending perforations. A pulse disc is retained within the body portion and has a conical face resting on the primary plate. Fluid flow through the body portion causes the disc to roll around on the primary plate and sequentially block the rows of perforations in the primary plate whereby pressure fluctuations are caused in fluid exiting the primary plate. In a preferred embodiment, an orifice plate is secured in spaced relation to the primary plate to form at least one pressure chamber therebetween. There is always a base pressure within each pressure chamber and rotation of the disc causes pressure fluctuations to be superimposed on this base pressure to cause pressure variations in the fluid exiting the orifice plate.
