FIRE-EXTINGUISHING DEVICE Russian patent published in 2005 - IPC

FIELD: fire-fighting, particularly aerosol generators for fire extinguishing used in stationary and movable systems to extinguish fire in vessels filled with inflammable liquid, in industrial objects and vehicles of all types.

SUBSTANCE: device includes a set of aerosol generators. Each aerosol generator has tubular body with aerosol-generation charge and container with fire-extinguishing powder arranged in the body. The aerosol-generation charge is provided with ignition member. Container with fire-extinguishing powder is arranged between gas-permeable grid and breakable membrane. Aerosol generator body consists of a number of tubular members to provide gas-permeable grid and breakable membrane fixation. Breakable membranes of each aerosol generator have different mechanical strengths and include weakening grooves formed at least in one plane thereof. Weakening grooves extend in radial direction and intersect in geometrical membrane center.

EFFECT: increased operational efficiency due to possibility of repeated device usage, increased technological effectiveness of device recharging and increased service life in static state.
