Abstract

En vannstråledrivenhet for skip som navigerer også i grunne farvann har et pumpehjul (3) sora suger vann i vertikal retning og er forsynt med blader som lar vannet strømme ut av pumpehjulet i en retning mellom vertikalt og horisontalt. Vannet som forlater strømningskanalen til pumpehjulet når en ringformet dif- fusor (5) uten blader, sora leder vannet pumpet av pumpehjulet inn i et trykkam- mer (23) etter å ha avbøyd det med 160° til 200° (fortrinnsvis 180°) i forhold til oppsugningsretningen. Det avbøyde vannet har bare lav strømningsenergi og forlater til slutt trykkammeret gjennom dyser (8) hvor avbøyningsretningen er fast eller variabel.
