Description

one

This invention relates to the provision of dp underwater hunting. .

A pneumatic pneumatic gun containing a barrel with a harpoon, a breech with a sear and a trigger hook, a hydraulic pump located in the handle, and a pneumoaccumulator with a charge connection lj are known.

The disadvantages of this device are the considerable force of cnycjM, as in a charged cutting pressure of water directly affects the harpoon, and the impossibility of safely discharging the rifle by discharging water, mine the barrel.

The closest to the invention in its technical essence is a hydro-pneumatic gun containing a barrel with a harpoon, a pneumatic accumulator with a charging nipple, a check valve, and ne | with a forced glass, placed in a rezxhovy hose sealed at the ends, a breech with a spring-loaded shut-off valve and an overflow valve built into it, a plunger, a plunger chamber and a working cavity, into the handle

with travel stop, spring-loaded trigger with travel stops, placed in the handle j. 2J.

However, in this hydropneumatic rifle, a small force on the trigger at the moment of descent and the ability to regulate the energy of the shot is achieved by introducing a locking device (valves and plunger), which complicates the design and operation of the rifle.

10 In addition, the gun does not allow for the discharge of water from the pneumatic accumulator of a torus without firing, i.e. safety of its operation is not ensured.

The purpose of the invention is to improve the safety of the ekaluatatsii gun and simplify its design.

Claims (2)

The delivered chain is achieved by the fact that in a hydropneumatic gun, we have a barrel with a harpoon, we have a pneumatic accumulator with a charging nozzle, a check valve and a perforated cup, which has been sealed at the ends of a rubber hose, a breech with a piston, a plunger chamber and a working cavity, and a spring-loaded trigger with a travel stop, placed in the hand, in the plunger there are separate L-shaped channels connecting: one zaarpunny trunk volume with the working cavity of the breech, and the druchey - working cavity with the plunger chamber, the first passage is provided with an elastic latch nym valve and the trigger is provided with podpruzhinen1aam pusher. FIG. 1 shows a hydropneumatic gun, a general view; in fig. 2 - section A-A in FIG. 1. The gun consists of a barrel 1, a harpoon 2 with sealing rings 3 on the tailing tube, a pneumatic accumulator 4 with a charging fitting 5, having a check valve 6, a fitting 7 and perforated steel bar 8, muffled at one end, a stopper 9 and a rubber hose 10 sealed at the ends 10. In the plunger chamber 11 of the breech 12, having a number of bypass holes 13, a plunger (spool) 14 is installed with two channels 15 and an elastic locking valve 16 covering the plunger 14 in the cavity 17 of the breech 12. Gun with handle 18, trigger 19 with Catel 20 and springs 21 and 22, as well as the stopper 23 moves. The gun works as follows. The internal cavity of the pneumatic attachment of the torus 4 is filled with compressed air through the non-return valve 6. To charge the rifle under water, the harpoon 2 is pushed into the barrel 1, overcoming the resistance of the compressed air in the pneumatic accumulator 4. The elastic stop valve 16 opens and the water is displaced from the barrel 1 through a series of bypass holes 13 into the perforated cup 8. After the harpoon 2 has stopped moving, the elastic shut-off valve 16 closes. For a shot, the stroke limiter 23 is moved from the position it occupied to charge the gun and protect it from accidental shot, and the trigger 19 is pressed. Overcoming the force of the spring 22, the trigger 19 moves the plunger 14 to the extreme position, opening the water passage Under pressure in the pneumatic bushing 4, the inlet flows from the perforated cup 8 through the bore holes 13 of the breech 12 into the cavity 17 of the breech 12 and further into the barrel 1. The pressure in the barrel 1 becomes equal to the pressure in the pneumatic accumulator 4, due to which the water exhausts No gyrpun 2. When water pressure force in the torus pnevmoakkumul 4 will spring 22 forces the plunger 14 and the trigger 19 are return to its original position and the gun is again ready for charging. To eliminate the idle shot, water from the perforated cup 8 is dropped into the reservoir by pressing the pusher 2O, which, overcoming the resistance of the spring 21, moves the trigger 19 and the grinder 14 until the channel 15 leaves the plunger chamber 11 into the cavity 17 of the breech 12, resulting in the release of water through the channel 15 and the plunger chamber 11 into the reservoir. If necessary, pulsed pressure on the pusher 2O is possible. reduce the energy of the shot. The proposed pneumatic pneumatic gun has a simplified design and increased safety in use in connection with the possibility of water being released from the pneumatic accumulator without firing a shot. The claims GidropnevmattEGcheskoe gun for underwater hunting, comprising a barrel with a harpoon pnevmoakkumul Torr with a charging nipple, the check valve and perforated glass, placed in sealed at the ends of the rubber hose, the breech of the plunger, the plunger chamber and the working chamber and a spring-loaded trigger with stroke limiter placed in the handle, characterized in that, in order to increase the safety of operation and control the design of the gun, separate l-shaped channels are split in the plunger, connecting - one harpoon volume working chamber of the barrel with the breech nick and the other - with the working chamber of the plunger chamber, the first passage is provided with an elastic shut-off valve and trigger - podsgruzhinennym pusher.
