Abstract:
A stream generating device for projecting a vertical laminar flow liquid stream comprising a canister having a liquid inlet port for connection of the device to a source of liquid at a uniform pressure and flow rate, said canister having a stream defining port, means within the canister for eliminating turbulence in liquid flowing under uniform pressure and flow rate from said source through said canister between said inlet port and said stream defining port, said stream defining port being round and having a sharp edge to form a laminar flow stream of said liquid projected continuously from said stream defining port, said device having means defining an outlet port aligned along a common axis with said stream defining port to pass said laminar flow liquid stream for projection along said axis beyond said device, diverting means between said stream defining port and said outlet port for selectively diverting said liquid stream within the device to prevent any of the liquid in said laminar flow liquid stream from passing through said outlet port,said device being oriented with said axis essentially vertical with the stream projected upwardly,a catching chamber having means defining a downwardly facing aperture to receive the upwardly directed liquid stream,diverter means within said chamber for redirecting the stream along a path within the chamber to prevent any liquid from the stream from falling back along the path of the stream between said downwardly facing aperture and said outlet port, and means for returning redirected liquid from said chamber to said liquid source.
