Abstract: A self-powered foam (e.g. compressed-air foam (CAF)) distributor has a rotor mechanism with impingement surfaces against which foam impinges to rotate the rotor. The rotor is mounted on an inlet shaft geared to an output shaft. A rotary outlet is mounted to the output shaft so that foam entering the distributor rotates the rotary outlet, which in turn projects foam around in a circular sweep. The rotary outlet can rotate over a full 360 degrees, providing superior coverage for a large floor space, such as in hangars or warehouses, with less water and concentrate than in unfoamed conventional systems. Having a compact vertical profile this versatile distributor can be installed in a floor trench of a hangar or on a wall or ceiling. Since all rotational energy is harnessed from the pressure of the foam itself, no external energy source is required to power the distributor.

Abstract: A rotary nozzle for compressed air foam (CAF) has a barrel mounted for rotation about an axis perpendicular to its longitudinal axis. The barrel is mounted to a CAF supply conduit and has a cross-sectional area substantially larger than the cross-sectional area of the conduit. Two non-equal orifices in the barrel, located on the opposite sides of the axis of rotation, distribute CAF such that it covers an almost complete, typically a circular area on the ground.
