Firearm with a Pressure Accumulator

Abstract

The firearm with pressure accumulator ( 5 ) having increased battering charge ( 3 ) and barrel ( 1 ) length has a piston ( 43 ) sliding in the accumulator housing ( 41 ) fixed to the breech ( 6 ) and springs ( 38, 38, 40 ) supporting the piston. To create a pneumatic spring ( 17 ) an annular brake chamber ( 44 ) is provided. The battering charge is arranged in the bolt body ( 31 ) located in the breech and has a neck ( 7 ) with an opening ( 9 ) facing towards the barrel to direct propellant gas to the barrel. This structure can be adapted to any size of the firearms, e.g. sharpshooter rifles with range of 4 to 6 kilometres, sky sweepers with an amplitude of 30 to 35 kilometres to combat targets by homing missiles as well as intercontinental missiles with a range of 500 to 1000 kilometres.

1 . An inventive firearm with pressure accumulator preferably for achieving large shot ranges characterised in that it comprises a significantly increased gunpowder charge ( 3 ) relative to earlier traditional firearms, and a barrel ( 1 ) having a uniform cross-section and also of a significantly increased length free of any lateral passages, and having a pressure accumulator ( 5 ) for absorbing the major part of gunpowder gases originating from the combustion of gunpowder charge ( 3 ) capable of breaking open the breech ( 6 ), and subsequent to the passing forward of the missile ( 2 ) in the barrel ( 1 ), the absorbed amount of gas flows from said pressure accumulator ( 5 ) into the barrel ( 1 ). 
   
   
       2 . Firearm according to  claim 1  characterized in that its pressure accumulator ( 5 ) is provided with a bore leading the gases of the combusting gunpowder charge ( 3 ) partly into the barrel ( 1 ), and radial bores ( 14 ) for leading the gases into the accumulator space ( 15 ). 
   
   
       3 . Firearm according to  claim 1  characterized in that its pressure accumulator ( 5 ) is provided in its breech ( 6 ) with a cylindrical space ( 11 ) and a ring piston ( 13 ) supported by a ring ( 13 ). 
   
   
       4 . Firearm according to  claim 1  characterized in that in the breech ( 6 ) of its pressure accumulator ( 5 ) two symmetrically ordered right side and left-side cylindrical. spaces ( 26 , 27 ) are situated. 
   
   
       5 . Firearm according to  claim 1  characterized in that its pressure accumulator ( 5 ) is provided with a bore ( 9 ) ensuring the flow of the gases originating from the combustion of gunpowder charge ( 3 ) partly into the barrel ( 1 ), and with another bore ( 42 ) leading the remaining gases to the opposite direction towards the pressure accumulator housing ( 41 ) mounted on the breech ( 6 ) from behind. 
   
   
       6 . The firearm according to  claim 5 , further further comprising an accumulator piston ( 43 ) supported by springs ( 38 , 39 , 40 ) placed into each other and sliding in the pressure accumulator housing ( 41 ) in a sealed manner. 
   
   
       7 . The firearm according to  claim 6 , further comprising a gas cushion ( 17 ) damping the impact exerted by the springs ( 13 ,  38 ,  39 ,  40 ). 
   
   
       8 . The firearm according to  claim 6 , wherein its accumulator piston ( 43 ) is provided with a supporting end ( 45 ) shaped in δ a plate form and supported by springs ( 38 ,  39 ) protruding from breech ( 6 ) backwards and placed one into another. 
   
   
       9 . The firearm according to  claim 6 , wherein the cylindrical space ( 11 ) of its accumulator space ( 15 ) is filled out with the gases formed by the combustion of gunpowder charge ( 5 ). 
   
   
       10 . The firearm according to  claim 6 , wherein the cylindrical space ( 11 ) of its accumulator space ( 15 ) is filled out with a neutral or a combustible gas introduced via gas connector ( 52 ) and valve ( 51 ).
