The invention discloses a unidirectional spray type fire extinguishing bomb without high explosive fragmentation, includes a housing, a fuse, an igniter, an fire extinguishing agent and a main charge, and further includes a tail braking device, combustor, a plate closure, a piston and a diffuser. The housing, the tail braking device and the piston are made of light metal materials; the housing is cylindrical; the tail braking device is arranged at the bottom of the housing and is fixed with the housing through a screw nail; and the fuse is arranged on the diffuser and is fixed through a screw nail. During working process, when the fuse detects the fire extinguishing bomb to be 5-10 meters far away from a combustion source, the igniter ignites the main charge, the piston is pushed under high pressure to move in the housing, and the fire extinguishing agent is sprayed out from spraying holes to the combustion source for fire extinguishing. The present invention has simple structure, and has no lethality when the fire extinguishing agent is sprayed.

The adjustment sleeve is sleeved on the nozzle, an inner side wall of the adjustment sleeve makes sealing contact with an outer side wall of the nozzle, the adjustment sleeve is disposed with a sealing plate having a water jet hole located right in front of the water outlet.

An integrated device for water streaming and spraying comprises a support base, a water inlet pipe mounted on the support base, a nozzle including an outer tube mounted on the water inlet pipe and an inner tube, an adjustment sleeve making sealing contact with the outer tube, and a position adjustment mechanism capable of adjusting a position of the adjustment sleeve along front and rear directions. The inner tube provided with a plurality of guide vanes is disposed in and protruding from the outer tube. A cavity of the inner tube is provided with a partition plate, the partition plate and an inner wall of the inner tube together encircle to form an opened diversion groove having a groove wall provided with at least one notch. The adjustment sleeve is disposed with a sealing plate having a water jet hole located right in front of the opened diversion groove.

A toy water gun having a stream interrupter or interrupter valve that is configured to periodically interrupt a flow of water that is discharged such that periodic bursts of water are delivered in a rapid succession. In one arrangement, a nozzle recovery chamber is provided in a nozzle opening of the nozzle is located that is directed to discharge water through the nozzle recovery chamber along a discharge axis. The stream interrupter is located in the nozzle recovery chamber between the nozzle opening and the discharge opening and is configured to periodically interrupt a flow of water from the nozzle along the discharge axis to the discharge opening to form the periodic bursts of water that are delivered from the discharge opening. Blocked water in the recovery chamber is recycled back to the supply tank. Use of the interrupter valve provides for interrupted discharges from the nozzle.

The invention relates to a water gun, in particular to a toy water gun comprising a supply line, which is adapted to supply a pressurized liquid from a source, a nozzle arrangement for ejecting the liquid to the environment as well as a valve for controlling a flow of the liquid in a direction from the supply line to the nozzle arrangement. The water gun additionally includes a flow-smoothing device, with the valve arranged behind the flow-smoothing device with respect to the flow direction.

Provided herein are fluid jet enhancement adapters for use with a propellant driven disrupter, and more particularly muzzle blast suppressor. The fluid jet enhancement muzzle blast suppressor may comprise a suppressor bore extending between the proximal end and the distal end with an inner suppressor surface that defines the suppressor bore. An outer suppressor surface opposably faces the inner suppressor surface, with a suppressor chamber positioned between the inner and outer suppressor surfaces. A plurality of passages connect the suppressor bore with the suppressor chamber, wherein the plurality of passages are sized to allow gas to move from the suppressor bore to the suppressor chamber and minimize liquid movement from the suppressor bore to the suppressor chamber.

Provided herein are fluid jet enhancement adapters for use with a propellant driven disrupter. The adapter may comprise: a first end operably connected to a muzzle end of a propellant driven disrupter barrel and a second end, wherein a longitudinal region extends between the first end and the second end. The longitudinal region has: a longitudinal region inner surface that defines a longitudinal region lumen; a longitudinal region outer surface opposably facing the longitudinal region inner surface, with a longitudinal region wall having a wall thickness that separates the longitudinal region inner surface from the longitudinal region outer surface. The longitudinal region lumen has a first end inner diameter that is substantially equivalent to a muzzle inner diameter. The longitudinal region wall forms a continuous surface that radially isolates the longitudinal region lumen from a surrounding environment.
