(54) HYDROPNEUMATIC GUN FOR UNDERWATER

HUNTING

{

BACKGROUND OF THE INVENTION The invention relates to a gun technician and represents a hydropnegmatic shotgun for underwater cattle.

Known hydropneumatic underwater gun of the submarine nipples, containing the hydraulic and shevgic cavities, barrel, harpoon, tench, mounted on the sleeve in the head part of the gun, and with a slide medanizm fl

The disadvantage of this gun is the complexity of the construction due to the presence of an additional sleeve for fastening the liner and the lack of accuracy due to the hydraulic effect on the protruding fastener elements of the liner during the movement of the harpoon.

It is also known and hydropneumatic gun containing barrel with hole-. for water and harpoon seals, pneumatic accumulator, elastic diaphragm, empty pneumatic and hydraulic cavities, trigger mechanism, tench and harpoon with installed one. on it the liner mounting sleeve and the tall-.

pom in the tail section to stop the liner hub when moving the harpoon 2j.

The disadvantage of this gun is the rapid deterioration of the harpoon seals, sleeve and the harpoon liner due to strikes of the harpoon on the sleeve | And seals during the shot.

The purpose of the invention is to improve the accuracy of shooting, the operation of the design; nn and increase the durability of the details of the schch.

to

The goal is achieved by the fact that in a hydropneumatic rifle containing a barrel with holes for water there is an pneumoaccumulator elastic ophagragm separating the pneumatic and hydratic cavities, harpoon, tench and spike-tide mechanism, the tail part of the harpoon is made in the form of a smooth cylinder, the gauche is placed in the trunk and fixed coaxially at the end of the tail part of the harpoon through

There is a 20th thickening at the end of the lin and a threaded BiynKH, and in the breech section of the pneumoaccumulus the mountain is installed for tight. S1 FIG. I shows a hydropneumatic gun for a fresh hunt, overall; incision; on fkg. 2 - scheme uklacki lin. The GU pneumopagia gun for spearfishing contains pneumoaccumul gf I, barrel 2 with microholes 3 dl -. passage of water. The pneumatic cavity is isolated from the hydraulic elastic oiaphragm 4, the cotta is sealed along the edge. The cylindrical harpoon 5 is compacted from leaking by charging and firing the gun with ring 6 and fixed in the charged position with a finger 7 for the annular recess 8. and cret1 to the harpoon with a threaded sleeve 11. To eliminate leakage, the wounds from the hydraulic cavity are made of a continuous polymer fishing line of circular cross section and sealed in the breech of the pneumatic accumulator with a ring 12, the trigger finger and EET lever 13 connected with the trigger draft type 14 installed on the drink spring 15, Pookachka pnevmoakkumul torus produ Dietz through hole 16, and this hole uploT11en11e accomplished elastic obrat1 th valve 17, made in the form of a ring. The rifle also has front 18 and rear 19 brackets for the lining: lin. .. The hydropneumatic gun for spearfishing operates as follows. Before firing, the pneumatic accumulator was blown into the air through the hole 16 and the check valve 17 until the required distance. The harpoon 5 is pushed up to the outlet of the barrel 2 by the bar and then pushed inside the barrel. At the same time, the sealing ring 6 of the harpoon 5 and Koldo 12 lin 9 ensure sealing. When charging the gun, the water passes through the microperforation 3 and, stretching the diaphragm 4, reduces the air of the pneumatic accumulator i ao aleny 5 §ar dki. the finger 7 fixes the harpoon in the barrel 2. Line 9 is selected by hand from behind and wound on the brackets 18 and 19. 44 For a shot, they start the trigger bar 14, smack the spring 15, hertz of the friction force in a pair of airgun-pults, and the lever 13 turn finger 7 around with Oei ocHt releasing the harpoon 5. Under the action of air pressure in the torus pnevmoak1 umul I water passes through the holes 3 into the barrel and ejects liberated harpoon 5. A) wb 9 is drawn through the breech ring ruzh and 12. Thus hydraulic tightness is maintained cavity. These features simplify construction; Since the number of parts is reduced, the size of the gauge is reduced, and the guideline for the liner is reduced, reducing the nausea of firing. Performing the Smooth tail garp of the harpoon increases the survivability of the ring of the b of the harpoon, since when fired, the harpoon moves without strikes with the details of the gun. Claims of the Invention Hydropnemagic eysuzh for spearfishing, comprising a barrel with holes for water, a pneumatic accumulator, an elastic diaphragm separating the pneumatic cavity and P1 hydraulic, harpoon, tench and trigger mechanism, so that that, in order to improve the accuracy of shooting, simplify pyjuirai conzis and increase the durability of the parts, it has a tail part of the raphyim Hora in the form of a smooth cylinder; The bushing, and in the breech part of the pneumatic actuator, was installed a sealing ring 0 for lin ,, Sources of information for use in aperture 1.
