aquí lo dejo traducido para el que quiera leerlo.
por lo visto esto es otro rollo. el fusil no tiene camara de aire. lo impulsaría la presión del agua, al existir vacío en la camara que queda al cargar.
si funciona o no ya es otro tema.
si no está muy bien traducido es problema del traductor. os pido disculpas :oops:
salu2

Vacuum is the gun
It goes without saying, the most original construction of all! Anywhere nothing to pump not necessary! The mother- earth works for us. The mother- atmosphere is more precise. With its honest of ykg\sm2 at sea level. And already 2kg\sm2 at the 10- meter depth in the sea itself... the word of honor, brilliant construction!
The operating principle of diagram is simplest - from one side of piston the vacuum, with another standard air pressure. The force of shot (in the kilograms) is equal to piston clearance (in the square centimeters). In space the gun will not be able to shoot... Then at the depth brutal power!
From minuses the fact that is required stocky pipe so that the gun it would come out sufficiently to powerful. Furthermore, gun chustvitel'no to the entry of large quantities of mud, which falls into the rear open end of pipe, what with the sea hunting exactly and does not occur... Well and the fact that after shot gun acquires large negative buoyancy... And still the inconvenience of the rear tying of harpoon....
In the sense to make that a rear tying it is possible, but the reliability of gun somewhat will suffer (slippery bushing with the sleeve it falls into the sand... yes and the section of bushing it is obtained large, be impeded against the water it will be strong...):
there was also in me this technology. It is it's a pity, tyuere are no fotok... it were screwed tighter to me as that on the market remarkable, meter length, the duralumin pipe of ya2khy,shch, in this case, already very qualitatively anodized, and s grow prettier by polishing inside. Well simply could not be from it not made vacuum gun. Here 4 it made. Understanding that its power not will be exceptional, constructed it under the harpoon of "mm. handle was placed from behind, hook made for the piston. (if we already and make, then it is solid!
).
By the way, about one special feature of the construction of vakuumnikov: it is necessary to take maximum measures for lightening and qualitative damping of piston. Since there it very large-dimension and the speed of motion the same as in harpoon.
In my gun the caprolon, thin-walled, strongly lightened piston stood. The padding 10 mm from the costume neoprene, stuck on the front silencer, worked as the shock absorber of piston. The sound of the percussion of piston was not at all distinguished with it. Hook was achieved by the wide polished (so that it would not scratch) duralumin sear directly for the edge of piston. Elastic packing to the piston it is necessary to select soft for the smaller friction against the stem.
On the impressions.
The length of gun was about 90 cm. in air the pushing out harpoon force was near y2kg. Therefore project it, let us say, hearth 9 mm harpoon it would be incorrectly. In my case the harpoon stood 7 mm. 4 it would place even thinner, but then it already perceptibly bent with the charging... Nevertheless, in spite of altogether only 12 kilograms of "power", the force of battle was more than sufficient. Not lastly because of the large length of the acceleration of harpoon in vakuumnike almost entire length participates in the acceleration. At least shooting proved to be considerably more interesting than from the elastic... There is no that brutal return with the shot. Yes even the maneuverability of naked pipe, it is considerably higher than pipe with the thrusts and the harpoon. What to the power of vakuumnik it shot clearly "long-rangeer" than that elastic, that i had. But in this case it made this soft, "it is more intelligent"... And it is very accurately! On the whole, with this gun, in my opinion, completely freely it was possible to hunt the same grey mullet on the distances to 2,5-3 meter. But more that is not must...
But this are all about the shooting at an "outboard" pressure in ykg/of sm2. When 4 it began to shoot meters per 10.... sensations such, that i have in the hands my customary zelinka- of metrovka with the rear knob, with which 4, I strictly and hunt always at sea... Power of shot absolutely at the same level! Here to you and toy.... So that for the zasadnoy hunting from the "lower maturation" - the completely suitable technology!
By the way gun it came out exceptionally quiet with the shot- nowhere the metal tert against the metal, nothing not it stuchit...
Then this gun found to itself new owner. Which sails, until now with it, and it is completely contented...
