LINEAR FIRE EXTINGUISHER Russian patent published in 1998 - IPC

FIELD: fire-fighting equipment. SUBSTANCE: the offered fire extinguisher has tubular body with fire-extinguishing agent and power drive for starting the device. Body is made in form of collector with spraying nozzles. Fire-extinguishing agent is used in form of charge of aerosol fuel and power drive ignites the charge over its entire length or on separate sections of collector length. Collector cross-section is shaped and has ejector, deflector or jet coolant. Collector cross-section may be made with variable radius of curvature. Collector may be separated into two hollows, one of which may accommodate aerosol fuel, and the other is communicated with nozzles. Hollows may be formed by concentric surfaces and nozzles may be installed in connectors of hollow walls. Connectors may be installed over the length of collector by helical line. Surface of internal hollow may be made of low-melting material, for instance, aerosol fuel. Collector may be made of flexible material, for instance, reinforced hose or from aerosol fuel. Power drive is located outside the collector and comes in contact with charge through nozzle openings or places of opening of outflow surfaces mounted in collector and spaced over collector length with different intervals. Power drive may also be made in form of electric drive with sections made of material with high electric resistance and may be coated with initiating compound. Power drive may be made in form of quick-burning safety fuse with the preset ignition temperature and brought out to outside through nozzles. EFFECT: higher efficiency. 18 cl, 7 dwg
