OPERATING DEVICE FOR FIRE FIGHTING Russian patent published in 2012 - IPC A62C31/22 A62C31/24 

FIELD: fire-fighting means.

SUBSTANCE: invention describes a working device and also a device for penetration of the working device for fire extinguishing with a located in the terminal region (2) of the arrow (3) of the working device, adjustable at least in one spatial direction of the device (1) of fire suppression and with adjustable relative to the device (1) of fire suppression device (8) for penetration with loaded pressure of hydraulic fluid from the hydraulic system (34) via at least one control valve by operating cylinder (35) of double action with a tube-shaped through piston rod (36). The latter is provided on the protruding end (14) with a tool (9) of penetration, which has a through hole and the nozzle head (15). At the other end (38) the piston rod (36) is connected with a line to fire extinguishing agent supply device, and a chamber (63) of discharge of the working cylinder (35), which when loading with pressure provides for movement of the loading of extension of the tool (9) of penetration, via the flux at least one element (76) of pressure accumulation is linked. With the return line (71) for hydraulic fluid from the pressure chamber (64), which when loading with pressure provides for retracting movement of the tool (9) of penetration by the flux to at least one additional element (79) of pressure accumulation is connected.

EFFECT: invention provides a rapid and effective action of the device.
