Abstract
A peripheral jet fire fighting fog nozzle having mounted on the discharge end thereof a stream-shaping sleeve provided with a convex end face adapted to form an open outer cone-like spray pattern and a plurality of circumferentially spaced fog teeth extending axially from the convex end face with axially extending convex lateral surfaces on the teeth adapted to spread the spray pattern laterally and fill in the lateral opening or gaps in the outer spray pattern. Rounded axially extending inner end surfaces provided on the fog teeth together with adjacent lateral surfaces of the fog teeth are adapted to form uniform droplets which are uniformly distributed within the interior of the outer conical spray pattern to form a uniform conical spray pattern which has a wide angle of divergence and is free of circumferential gaps.
