LINEAR BARREL NOZZLE WITH LINEAR DRIVE Russian patent published in 2021 - IPC A62C31/02 

FIELD: fire-fighting equipment.

SUBSTANCE: invention relates to fire-fighting equipment, in particular to devices for supplying extinguishing agent, namely to the nozzles. The effect is achieved by the fact that the body is made along the outer and inner surfaces in the form of a stepped sleeve. The inner surface of the outlet end of the latter is made in the form of a differentiated surface. The body is equipped with an extinguishing agent flow damper and an extinguishing agent jet geometry shaper. On the body and on the shaper, respectively, a bracket and an additional bracket are made, in which the earrings of the linear movement control mechanism are installed. The outer surface of the former geometry of the jet of extinguishing agent is equipped with a gear rim on the side of the end of the outlet opening. The screen is made in the form of a cone and is installed at the end of the extinguishing agent flow damper, while the base of the cone is located outward from the side of the extinguishing agent jet geometry former.

EFFECT: possibility of creating a change in the geometry of the jet of the supply solution, depending on the tasks, by achieving its finely sprayed expanded angle of the treated surface with an increase in the range of the jet of extinguishing agent. In addition, a simplification of the design and technology of its manufacture is achieved.
