Abstract (en)
[origin: US5567079A] PCT No. PCT/EP93/03195 Sec. 371 Date May 16, 1995 Sec. 102(e) Date May 16, 1995 PCT Filed Nov. 15, 1993 PCT Pub. No. WO94/11580 PCT Pub. Date May 26, 1994The invention relates to a method and an apparatus for the hydraulic branching of an open stream having at least one straight main stream of a specific momentum and having one or more branch streams. Deflection from the main stream is brought about using the Coanda Effect. The hydraulically working channel, i.e., the main stream channel has an upstream corner in common with the branch stream channel which corner is rounded in the form of an arc of a circle between the upstream channel and the branch channel and which converges toward the corner and extends opposite that wall of the upstream channel leading toward the corner and forms with the corner an outflow gap, such that the momentum of the main stream flow which emerges, creates the Coanda Effect, thereby deflecting the controlled flow of water into the branch channel.
