Definitions

  • the invention relates to a compressed gas container for gas pressure sports weapons, consisting of a tube which forms a retracted base at one end and has a breech head equipped with a valve which opens when the container is screwed onto the weapon.
  • the weapon in question namely a pistol or a rifle for screwing on the compressed gas container, in particular a CO2 container
  • a screw attachment which is pierced in the axial direction, the bore opening into a pressure chamber which is closed by a valve through a channel connected to the barrel of the weapon behind the cartridge.
  • Valve closing the channel leading to the barrel is briefly opened when the trigger device of the weapon is actuated by means of a striker or the like, so that the compressed gas can reach the projectile through the channel.
  • the compressed gas tank can of course be refilled after emptying. Due to the physical properties, however, the pressure in the pressurized gas container changes with the temperature and the degree of filling Compressed gas or CO2. At a filling level of around 50% and at a temperature of around 20 ° C, the pressure in the container is around 60 bar. This pressure prevails after the container is screwed onto the weapon, also in its pressure chamber. If the pressure in the container rises due to overfilling and / or too high a temperature, but the energy of the firing piece of the weapon acting on the firing pin remains the same, the amount of compressed gas released changes, which of course affects the speed of the projectile, which again has adverse effects can have the accuracy of the shot.
  • the invention is therefore based on the object of eliminating these deficiencies and of creating a pressurized gas container of the type described at the outset, in which pressure fluctuations are substantially avoided, that is to say no inadmissible overpressure can occur and which practically always remains useful for the shooter.
  • the invention achieves the stated object in that an additional valve leading into the open is provided and the pretensioning force of the spring loading the valve body thereof can be preset.
  • the bias of the spring of the additional valve is thus set from the outset to the desired internal pressure corresponding size, so that pressure fluctuations by independent blowing off the excess CO2 or the like. Can be kept within certain limits, in order to eventually speed the projectile as possible keep the same and increase the accuracy of the shots.
  • the additional valve also acts as a safety device, which has the advantage that the container remains functional after it has responded. The weighing process when refilling the compressed gas container is not made superfluous, but this is only used to determine the amount of compressed gas or CO2 still present.
  • the valve body of the additional valve consists of a cylinder sleeve guided in a bore and accommodating the spring, the bottom of which faces the valve seat and is optionally provided with a sealing pad in its edge area at least one passage opening into the interior of the sleeve having.
  • a filter is arranged upstream of the valve seat of the additional valve towards the interior of the container, so that no dust particles or the like can get onto the valve seat.
  • the additional valve is preferably in the closure head orderly. It is also possible to design the additional valve as a separate unit screwed into the closure head or container bottom, which can then be easily adjusted from the outset to the desired internal pressure and only needs to be screwed into the closure head or container bottom.
  • the compressed gas or CO2 container consists of a tube 1, which forms a retracted bottom 2 at one end and is provided with a screwed-in closure head 3 at the other end.
  • the closure head 3 has a valve 4, which is opened when the container is screwed onto a screw attachment of the weapon, which penetrates into the threaded bore 5, via the pin 6 by lifting the valve body 7 from its seat 8.
  • valve 9, 9a, 9b is now provided, which according to FIG. 1 is arranged in a bore of the closure head 3.
  • the valve body 10 consists of a cylindrical bushing guided in a bore 11, the bottom 13 of which, facing the valve seat 12 and provided with a sealing pad 13a, has two through openings 14 into the inside of the bushing in its edge region and receives a compression spring 15.
  • the valve seat 12 can be adjusted to change the bias of the spring 15 in the closure body 3 by screwing, the actual one A filter 16 is arranged upstream of the valve seat towards the interior of the container.
  • the additional valve 9a is not arranged in the closure head 3, but has its own cylindrical housing 17 which is screwed into the bottom 2 of the container.
  • the valve spring 15 can be preloaded to the desired level by relative rotation of the valve seat 12 relative to the housing 17.
  • the additional valve 9b can also be screwed into the valve head 3 as a structural unit, the valve seat 12 being formed in one piece with the housing 17 and the abutment 18 of the spring 15 in the housing 17 being screw-adjustable to change the spring preload.
