Description

456 412 kanalförsedda stycket 7, och tillsluta kanalen/kanalerna 5 resp 3 och förhindra att vätska tränger ut át fel håll, utan kan tvingas att ledas i riktning 9 mot utloppsänden 3A hos den utloppskanal 3, som kan sträcka sig tvärs genom det stycke 7, som kanalen 3 är anordnad i. 456 412 ducted 7, and close the duct (s) 5 and 3, respectively, and prevent liquid from penetrating in the wrong direction, but may be forced to be directed in direction 9 towards the outlet end 3A of the outlet duct 3, which may extend transversely through that in which the channel 3 is arranged.

Tillföringskanalen 5 mynnar tangentiellt till utloppskanalen 3, exempelvis såsom visas pá ritningsfigurerna l och 2.The supply duct 5 opens tangentially to the outlet duct 3, for example as shown in drawing figures 1 and 2.

Utloppskanalen 3 kan vara anordnad konisk eller på annat lämpligt sätt avsmalna i riktning mot dess utloppsände 3A, samt kan uppvisa ett väsentligen jämntjockt företrädesvis cylindriskt kanalformat parti 3C vid sagda kanals utloppsände 3A.The outlet channel 3 can be arranged conically or otherwise suitably taper in the direction of its outlet end 3A, and can have a substantially evenly thick, preferably cylindrical channel-shaped portion 3C at the outlet end 3A of said channel.

Vätska, som tillföres i riktningen 6 i till- föringskanalen 5, kommer tack vare förekomsten av den tangen- tiella placeringen av kanalen 5 i förhållande till utlopps- kanalen 3 att omlänkas mjukt. Vätskan kommer att virvla i riktning av pilen 10 utmed mantelväggen ll hos åtminstone den del 3D av kanalen 3, som är belägen vid änden 3B av sagda utloppskanal 3, och därigenom omlänkas mjukt. Er vinkel V på 900 mellan kanalerna 5, 3, såsom visas pá ritningen, möter inga hinder utan vätskan matas jämnt i riktningen 9 mot avsett utlopp 3A.Liquid, which is supplied in the direction 6 in the supply channel 5, will be softly deflected due to the presence of the tangential position of the channel 5 in relation to the outlet channel 3. The liquid will swirl in the direction of the arrow 10 along the jacket wall 11 of at least the part 3D of the channel 3, which is located at the end 3B of said outlet channel 3, and is thereby gently deflected. Your angle V of 900 between the channels 5, 3, as shown in the drawing, does not meet any obstacles, but the liquid is fed evenly in the direction 9 towards the intended outlet 3A.

Uppfinningen är ej begränsad till det ovan beskrivna och på ritningarna visade utföringsexemplet utan kan varieras inom ramen för patentkraven utan att uppfinningstanken frángás. (in kv:The invention is not limited to the exemplary embodiment described above and shown in the drawings, but can be varied within the scope of the claims without departing from the spirit of the invention.
