Abstract
A nozzle assembly including a nozzle unit, first and second sleeves and a clamp. The nozzle unit has an aft collar and a tapered inner fluid contact surface, tapering to gradually increase the velocity of fluid passing therethrough. The inner surface is formed of an elastomer material that deforms by eddies in the fluid and thereby does not build turbulent flow. The clamp encircles a rearward fitting of the first sleeve and a forward fitting of the second sleeve, holding them together with the collar sandwiched therebetween.
