ABSTRACT OF THE DISCLOSURE The specification describes a fluid flow device for producing a combustible air-liquid fuel mixture comprising a wall means defining at least one passageway including a gradually converging air entrance zone, a variable area throat zone through which air and liquid fuel are passed at sonic velocity, and a gradually diverging downstream zone, the wall means comprises a pair of spaced apart opposite stationary large jaws and a pair of opposite small jaws mounted for relative movement toward and away from one another to vary the area of the throat zone, the opposite small jaws each having an angle of convergence in the upper portion of the air entrance zone, a flat portion extending therefrom to slightly below the throat zone, and a slight angle of divergence in the lower portion of the diffuser zone, fuel supply means, and fuel delivery means for introducing fuel into the passageway at or above the throat zone where the small jaws are flat.
