(under the class definition) Apparatus having, in addition to the necessary fluid supply and/or handling elements providing a normal flow for spraying and the like, means to stop periodically and cyclically the total flow of fluid to the entire terminal outlet means and then restore the normal flow therethrough.
(1) Note. The cycle or period may be of any duration but there must be a clear disclosure of a complete stoppage of supply of discharge fluid to the terminal outlet means for a distinct interval.
(2) Note. The means for interrupting the supply 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.
