FIELD: fire fighting equipment.
SUBSTANCE: invention relates to fire equipment, namely to design of fire extinguishers, and can be widely used in development and production of fire extinguishing means. Powder extinguisher comprises housing, shut-off device with siphon tube, nozzle, fire extinguishing agent and displacing gas. Cavity with displacing gas is separated by rigid and sealed partition with aerator from cavity with fire extinguishing substance. In the partition there is a valve contacting through the assembled hollow pusher with the shut-off and starting device. At the same time partition is made in the form of truncated cone, and assembled hollow pusher is made with possibility of its installation into fire extinguisher through holes made in partition, bottom and aerator.
EFFECT: providing tightness of the fire extinguisher to powder filling, control of powder state and its recharging without pressure release in cavity with displacing gas.
