- 2. A liquid disrupter as defined in claim 1, wherein each said recoil tube is provided with a bored cap threadingly engaging its rear end, said cap holding said rear frangible seal and integrally carrying said transverse blade for dispersing the fluid jet being ejected out of said recoil tube.
- 3. A liquid disrupter for deactivating a bomb comprising:a main elongated hollow barrel having a rigid cylindrical body with an inner chamber, a closed rear end and an opened front end closed with a front frangible seal; a channel member having a bore engaged by said barrel, said channel member being securely attached to said barrel; at least two recoil channels equally peripherally spaced about said barrel, said recoil channels having a first end extending through said barrel cylindrical body and opening inside said barrel inner chamber at a section thereof intermediate said front and rear ends, and a second end rearwardly opening out of said channel member and closed with rear frangible seals, said recoil channels radially outwardly and rearwardly extending through said barrel cylindrical body and said channel member from said first to said second ends; a remotely selectively controlled trigger member operatively mounted to said barrel; wherein in operation, an explosive charge is to be placed inside said barrel inner chamber near said rear end and connected to said trigger member, and said barrel body inner chamber and said recoil channels are to be filled with fluid, and wherein upon the explosive charge exploding when it is detonated by said trigger member, a portion of the fluid is ejected at high velocity frontwardly out of said barrel front end, rupturing said front frangible seal, to puncture the bomb outer shell and deactivate the bomb inner detonating components, and another portion of the fluid concurrently engages said recoil channels, rupturing said rear frangible seals, to be rearwardly ejected out of said channels, which at least partly counteracts the rearward recoil resulting from the explosive charge projecting the water frontwardly out of said barrel;wherein each said recon channel includes a first and a second channel sections, said first channel section extending through said barrel and said channel member in a radially outwardly and rearwardly inclined fashion relative to said barrel, and said second channel section being a recoil tube securely attached to said channel member and rearwardly projecting from said first channel section, said recoil channel second end being located at the rear end of said recoil tube; andwherein said barrel includes a radially protruding peripheral shoulder intermediate said front and rear ends, with said channel member including an inner peripheral channel member seat about said bore for seating abutment against said barrel shoulder, said disrupter further including an attachment ring axially engaging said barrel and including an inner peripheral ring seat for seating abutment against said barrel shoulder opposite said channel member, said ring threadingly engaging said channel member to securely attach said channel member against said barrel.
- 4. A liquid disrupter as defined in claim 3, wherein said first channel section extends through said barrel and through said barrel shoulder.
- 5. A liquid disrupter as defined in claim 3, wherein said barrel front end portion is provided with a securely attached nozzle holding said frangible seal against said barrel front end, said nozzle being conically shaped to accelerate the outgoing fluid jet with its conicity inner diameter radially inwardly decreasing axially frontwardly toward said nozzle mouth.
- 6. A liquid disrupter as defined in claim 5, wherein the nozzle conicity angle is of about 15°.
- 7. A liquid disrupter as defined in claim 3, wherein said barrel rear end is releasably closed with a removable cover securely attached to said barrel, said cover carrying said trigger member.
- 8. A recoil-less water gun comprising:a main elongated having a main rigid body with a first channel, for receiving and holding a volume of water and provided with a front water outlet end mouth and a rear closed end portion, said first channel rear end portion including a well for receiving an explosive charge; a tubular array integrally mounted in radially outward fashion to a section of said main barrel body intermediate said front and rear end portions thereof, said tubular array consisting of at least two elbowed tube members, said tube members being peripherally equidistant to each other; each elbowed tube member having:a forward portion, mounted to and radially outwardly rearwardly extending from said barrel intermediate section and defining a second inner channel, said second channel extending through said barrel body and in liquid communication with said barrel first channel, and a rearward portion, extending in radially spaced parallel fashion relative to said barrel rear end portion and defining a third inner channel in liquid communication with said second inner channel of the latter tube, each one of said third inner channels having a rear water outlet mouth; wherein each of said second channels extend radially inwardly into said first channel, to define peripherally spaced water flow deflecting ribs, located inside said barrel first inner channel and peripherally of said first channel; andwherein in operation, upon loading a volume of water to fill said first, second and third channels and upon ignition of an explosive charge inside said well, a portion of this volume of water is ejected forwardly along said barrel first channel and outwardly through said barrel front outlet end mouth, while a remaining portion of this volume of water is backflowed rearwardly radially outwardly into said tube members to be ejected rearwardly, whereby the water gun recoil is controlled.
- 9. A recoil-less water gun as in claim 8, wherein the diameter of each of said second channels is identical to one another but diametrally smaller than any one of said first and third channels.
- 10. A recoil-less water gun as in claim 9, further including water dispersal members, each mounted to a corresponding one of each of said tube member rearward portion rear outlet mouths, said dispersal members for wide angle dispersal of water flow ejected rearwardly through said rear outlet mouths.
- 11. A recoil-less water gun as in claim 10, further including a dynamic pressure sensitive frangible seal mounted to at least one of said front outlet end mouth of said barrel and of said rear outlet end mouths of said tube members.
- 12. A recoil-less water gun as in claim 8, each of said second channels extending radially inwardly into said first channel, to define peripherally spaced water flow deflecting ribs, located inside said barrel first inner channel and peripherally of said first channel, wherein said deflecting ribs assist in the water backflow rearwardly radially outwardly into said tube members after ignition of the explosive charge.
- 13. A. recoil-less water gun as in claim 8, wherein said barrel front end mouth is conical, for reducing the barrel diameter at its frontmost end to produce a more powerful jet of frontward water flow.
- 14. A recoil-less water gun as in claim 13, wherein the conicity angle of said barrel conical front end mouth is about 15 degrees.
- 15. A recoil-less water gun as in claim 12, wherein said barrel front end mouth is conical, for reducing the barrel diameter at its frontmost end to produce a more powerful frontward ejected water flow.
- 16. A recoil-less water gun as in claim 15, wherein the conicity angle of said barrel conical front end mouth is about 15 degrees.
