THREE-DIMENSIONAL AEROSOL FIRE EXTINGUISHING APPARATUS Russian patent published in 2012 - IPC A62C13/22 

FIELD: medicine, fire-fighting means.

SUBSTANCE: invention refers to fire-fighting, namely extinguishing gas-aerosol mix generators actuated by pyrotechnic compound burning and spraying the mix into the protected space. A three-dimensional aerosol fire extinguishing apparatus comprises axially coupled cooling cylinder, and a generator body with a heat-insulating inner layer. The cylinder is provided with injection windows and mounted on a bearing arm with an angularly positioned longitudinal axis. The layer fixes a functional pyrotechnic stick connected with a central ignition cartridge represented in the form of a pyrotechnic tablet filled with a hermetic adhesive in an axial groove of the pyrotechnic stick. The ignition cartridge is wired with a hermetic switchboard of an external startup unit. The body is lidded with the lid comprising distributed outlets above a receiver wherein an isolating membrane is provided. The hermetic switchboard is mounted on the generator body by a threaded carrier sleeve with its flange attached in plaster of its heat-insulating layer which incorporates the wires to the central ignition cartridge.

EFFECT: invention provides enhanced technological capabilities of the use of the apparatus in the high atmospheric moisture and explosive environment.
