Abstract:
1. A fluid discharge apparatus for producing a curtain of air comprising a body member having an air inlet chamber and an air outlet chamber, the air outlet chamber being in fluid communication with the air inlet chamber, the body member defining a discharge orifice through which fluid is discharged from the body member, the discharge orifice being in fluid communication with the air outlet chamber, said air outlet chamber has a pair of opposing sidewalls, each of the sidewalls having an angled sidewall portion, said angled sidewall portions being arranged to converge towards each other as the angled sidewall portions extend in a downstream direction towards the discharge orifice so as to define a generally V-shaped lead-in section that guides and directs fluid towards the discharge orifice, said body member including a base portion and a blade portion having parallel mating surfaces that are secured in adjacent relation to each other, said discharge orifice being defined by respective outer edges of said base and blade portions, and one of said outer edges being defined by an extended wall that extends downstream past the other outer edge so as to define a deflection surface for the discharging fluid that extends along one side of the discharge orifice.
