DEFINITION
Classification: 239/102.1
WITH MEANS TO VIBRATE OR JIGGLE DISCHARGE:
(under the class definition) Apparatus having means in addition to the necessary fluid supply and/or handling elements for spraying and the like, said means being driven by a motor means in order to change rapidly and periodically or cyclically the normal character of discharge from a terminal outlet or to change the normal character of the flow pattern, spray or trajectory downstream of said outlet.
(1) Note. The means to change the flow characteristics of the discharged fluid may include means to superimpose a rapid wave motion on the normal fluid stream by (1) continuously moving the discharge outlet member, or (2) continuously moving a member in contact with the fluid, before, after or during discharge.
(2) Note. The vibrating flow means must vary some instantaneous flow characteristic of the sprayed fluid, and means to move a nozzle or deflect a discharged fluid for the mere purpose of distribution over a desired area are excluded and will be found in pertinent subclasses herebelow.
