Injection head to be installed to discharge the liquefied fire-extinguishing agent to the fire-extinguishing subject area in the fire-extinguishing equipment to use the liquefied fire-extinguishing agent, and it is equipped with injection head proper to which piping to supply the liquefied fire-extinguishing agent is connected, orifice plate forming orifices installed to the injection head proper, block-shaped porous member 4 installed at the outlet of the orifices, and deflector installed across discharging clearance of the liquefied fire-extinguishing agent to the porous member.

A modular fluid jet attack system provides a system and method for both the containment of spreading flames and extinguishing a fire. A fluid jet system delivers high pressure fluids and abrasive materials to cut a hole in a wall. After the hole is cut, a firefighter can selectively stop the flow of abrasive material to provide fluid only for fire suppression using small droplets on the order of 150 microns. The fluid jet system can employ a gas system to tactically deliver a gaseous agent to aid in a military or law enforcement operation, or to deliver a gaseous agent for use in a firefighting operation, such as an electrical fire. Portions of the fluid jet system, the gas system and the attack system can be mounted in or on a vehicle, trolley, or case for portability.

A full jet nozzle for use with a water cannon, the nozzle having a body that encloses a flow channel running along an axial direction, having an outlet opening provided at an axial end of the flow channel, which has an external circumference which encloses an outlet surface to form a flow cross-section. The flow cross-section has a substantially circular or annular base area. There is at least one radial cross-sectional extension of the outlet area is provided exclusively in an angular range of the outer circumference of a maximum of 180. The full jet nozzle also has at least one radial cross-sectional extension formed by a slot running with its longitudinal axis parallel to the axial direction, which opens perpendicular to the base area or has a recess running with its longitudinal axis parallel to the axial direction, which opens perpendicular to the base area.

Illustrative embodiments of the disclosure are generally directed to barrier-piercing firehose nozzle assemblies suitable for selective application of water and/or other extinguishing liquid to an open fire or piercing a ceiling, floor or other barrier and applying the liquid to a fire concealed above, below or on the other side of the barrier. An illustrative embodiment of the barrier-piercing firehose nozzle assemblies may include a nozzle inlet housing having an inlet housing interior. A spray nozzle may be disposed in fluid communication with the inlet housing interior. A barrier-piercing applicator may be disposed in fluid communication with the inlet housing interior. The barrier-piercing applicator may be selectively deployable between a retracted position and an extended position. At least one discharge opening may be provided in the barrier-piercing applicator. A selector valve may be provided in the inlet housing interior. The selector valve may be selectively deployable in a first valve position in which the selector valve is disposed in fluid communication with the spray nozzle and a second valve position in which the selector valve is disposed in fluid communication with the barrier-piercing applicator.

One or more techniques and/or systems are disclosed for a foam fluid dispensing device that allows for quick and easy adjustment between a straight stream and dispersed stream. A user can quickly adjust between various stream patterns using a common motion in nozzle operation. An example device can comprise a nozzle comprising a nozzle body and an inlet configured to receive a flow of fluid, with a nozzle stem centrally disposed in the nozzle and fixedly engaged with the nozzle body. The device can also comprise a foam tube configured to receive and dispense at least a portion of the flow of fluid from the nozzle, with a foam tube coupler fixedly engaged with the foam tube. The foam tube coupler can be configured to operably couple with the nozzle stem.
