ABSTRACT:
The two-dimensional adjustable nozzle according to the invention is a generally rectangularly shaped nozzle having a pair of opposite, fixed sidewalls defining the lateral boundaries of the nozzle and adjustable flap assemblies extending between the lateral walls and defining the upper and lower boundaries of the nozzle. The adjustable flap assemblies each have an interior flap and an exterior flap associated with a rocking lever which, in turn, is connected to an actuating mechanism. The actuating mechanism, which may be a jack screw, is located within the lateral sidewalls and is controlled by a rotatable cable. Rotation of the jack screw shaft which is connected to the rocking levers, causes the rocking levers to move in a direction generally transverse to the longitudinal axis of the nozzle to thereby adjust the angular positions of the interior and exterior flaps.
