(under the class definition) Apparatus having in addition to the necessary fluid supply and/or handling elements for spraying and the like, means to vary continuously and cyclically the total rate of flow of fluid to the entire terminal outlet means and/or to change cyclically the pressure of the fluid supplied to said entire terminal outlet means.
(1) Note. The cycle may be of any desired duration but must repeat itself.
(2) Note. The means for varying the rate of fluid must be in addition to all the various confining surfaces which collectively bound and define an essential flow path but said means may include (1) fluid passage or chamber means which, if closed off from the flow path, would not affect normal discharge flow, and/or (2) motor surfaces disposed out of the normal and direct path of fluid to the terminal outlet means.
SEE OR SEARCH THIS CLASS, SUBCLASS:
17+, for an ornamental fountain in which the fluid flow or pressure may be cyclically varied.
97, rotary distributors in which the fluid supply to successive spray arms and the like may vary.
99, for intermittent interruption of fluid supplied to the distributing means. 380, for motor or spray operated continuously moving discharge modifier and not having the additional means required by (2) Note above.
