Fremgangsmåde og apparat til at afbryde fluidumstrømme

摘要

A method and apparatus for forming and selectively interrupting one or more fluid stream which is confined within an open channel. A transverse fluid stream is introduced into the channel at a point under the stream flowing within the channel. Introduction of the transverse stream at relatively low pressures is sufficient to cause the stream within the channel to leave the confines of the channel. If the channel is directed at a target, the method and apparatus will allow intermittent and selective interruption of a fluid stream flowing within the channel and directed at the target. The source of the transverse fluid stream has an arcuate or curved outlet portion to prevent fluid from the open channel from accumulating therein.
