Definitions

  • the invention relates to a gas pressure weapon with a for receiving a projectile serving storey chamber and one for introducing a pressurized gas into the storey chamber serving compressed gas channel.
  • Such gas pressure weapons are usually used in the form of sports weapons for competition purposes used, the propulsion of the projectile through the bullet chamber introduced compressed gas is generated.
  • the storey chamber is usually used formed by the end of the barrel of the weapon opposite the barrel muzzle.
  • to Firing a shot is a release device by actuating the trigger of the gas pressure weapon triggered with the introduction of the compressed gas from the Compressed gas chamber is released into the storey chamber.
  • This release facility usually comprises a spring-loaded hammer and a valve assembly, wherein by pulling the trigger the spring piece in Direction on the valve assembly is accelerated and this opens, so the initiation release the compressed gas into the storey chamber.
  • Modern gas guns are usually equipped with a detachable one and equipped with a pressurized gas container that can be filled at a separate filling station.
  • a pressurized gas container that can be filled at a separate filling station.
  • the pressure control unit ensures that the pressure in the working chamber even when the pressure in the removable compressed gas tank is reduced before firing a shot constantly at a predetermined value, such as 60 bar, is set. This is usually done by a pressure spring-loaded valve mechanism reached, which the filling of the working chamber from the compressed gas tank automatically stops as soon as the pressure in the working chamber reaches the specified value reached.
  • the object of the invention to provide a gas pressure weapon of the type described above, with which high accuracy can be achieved over a long period of time.
  • this object is achieved by developing the known gas pressure weapons solved, which is essentially characterized in that in the compressed gas channel at least one filter element for cleaning the compressed gas is arranged is.
  • This invention is based on the knowledge that when using the known Weapons-observed decrease in accuracy not only on the decreasing Concentration of the shooter, but also largely due to the fact that with the pressurized gas impurities in the pressurized gas channels of the pressurized gas container and the Pressurized gas weapons are introduced. These impurities can affect the flow behavior of the compressed gas in the compressed gas channel of the projectile chamber and / or the course of the Change gas pressure weapon so that there is a change in the hit position and thus to a Decrease in hit accuracy comes. In addition, dirt particles can accumulate the sealing surfaces of the valves and in the overflow channels, causing leaks and lead changes can result.
  • this defect thereby eliminated that the impurities are disposed in the compressed gas duct Filter element are removed from the pressurized gas in order to maintain a constant flow behavior and thus also ensure a constant accuracy of hits. It is particularly useful if the filter element in the flow direction of the Compressed gas before the usually provided and by actuating the trigger Introducing the compressed gas into the compressed gas chamber released in the projectile chamber is because in this way it can be ensured that in the for the determination part of the compressed gas channel in the hit position no impurities, such as Dirt particles or the like be introduced.
  • modern gas pressure weapons have one with a valve arrangement, gas-tight, removable compressed gas container which can be filled at a separate filling station.
  • it is a first section of the compressed gas channel formed by the valve arrangement of the compressed gas container, during a subsequent second section of the compressed gas channel remains in the weapon after removing the pressurized gas container.
  • the filter element both in the first section of the compressed gas channel and in the second section of the compressed gas channel can be arranged.
  • the Use of such gas pressure weapons is thought, in which both in the first section of the Compressed gas channel as well as at least one in the second section of the compressed gas channel Filter element is arranged.
  • the compressed gas channel can already be filled via the first one when the compressed gas container is filled Valve assembly containing the introduction of contaminants into the section Pressurized gas containers can be prevented.
  • the arrangement of the filter element in the in the gas gun remaining second section of the pressurized gas channel can be an additional Contamination or damage to the filter element during the filling process be prevented. This increases the durability of the filter element.
  • a removable Compressed gas tanks equipped gas pressure weapons one for adjusting the pressure of the in have the gas chamber to be introduced pressure control device, with which is the gas pressure in the working chamber from which the gas to be introduced into the storey chamber Compressed gas is removed, is set to a constant value.
  • the gas chamber to be introduced pressure control device with which is the gas pressure in the working chamber from which the gas to be introduced into the storey chamber Compressed gas is removed, is set to a constant value.
  • at least one filter element on the upstream side the pressure control device ie in the direction of flow of the compressed gas in front of the latter Pressure control device is arranged. In this way, impairment of Function of the pressure control device, which is decisive for a change in the hit position determining pressure in the working chamber, reliably prevented become.
  • Usual valve arrangements of removable compressed gas containers have a Recessing the container or a container closure and when attaching the container on the weapon or a filling station the release of the first Section of the pressurized gas duct causing the plunger. In this case it turned out to be proven particularly favorable if at least one filter element in a part of the first section of the pressurized gas channel forming annular gap between the inner boundary surface the recess and the plunger is arranged.
  • At least one filter element for example sintered metal fibers, balls and / or filter bodies made of a ceramic Material because these materials withstand the mechanical stresses caused by the high pressure differences and flow velocities when using gas pressure weapons Resist particularly well and therefore have a particularly high durability.
  • the part of the gas pressure weapon shown in the drawing includes the rear end the barrel 10 of the weapon, the front end of a handle or shaft 30 of the weapon and the rear end of a removable compressed gas tank 20.
  • the removable compressed gas tank 20 consists essentially of a jacket 22, in which the shaft 30 facing End one serving for releasable attachment of the compressed gas container to the shaft 30 Coupling element 24 is inserted.
  • the coupling element is of an axial recess 28 enforced.
  • the end facing the interior of the compressed gas container 20 a web 28 runs around the recess. This web 28 forms together with a check valve pressed against it with the aid of a pretensioning device of the pressurized gas container with which the outflow of the pressurized gas from the pressurized gas container can be prevented.
  • a plunger 26 is inserted with play such that between the inner boundary surface an annular gap is left free of the axial recess and the plunger 26.
  • the O-ring 29 with The plunger 26 is automatically lifted off the web 28. Then the compressed gas from the compressed gas tank 20 through the between the plunger 26 and the inner boundary surface of the axial recess formed annular gap 40 in the direction of Flow handle or barrel 30 of the gas pressure weapon.
  • This annular gap 40 forms a first Section of the for introducing the compressed gas into the one facing away from the barrel mouth rear end of the barrel 10 formed floor chamber 50 serving compressed gas channel.
  • the compressed gas flows into one after removal of the compressed gas container 20 from the weapon remaining in the weapon further section 34 of the pressure gas channel, which in a pressure control device designated overall with 32 empties.
  • a pressure control device designated overall with 32 empties.
  • the pressure in a subsequent working chamber 60 on one freely selectable constant value of 60 bar, for example.
  • release devices are known per se and are therefore not described in more detail explained.
  • the embodiment of the invention shown in the drawing has two in the Compressed gas channel arranged filter elements 36 and 38, one of which in the first section of the compressed gas channel forming the annular gap between the plunger 26 and the inner boundary surface of the recess passing through the coupling element 24 is arranged and the other in the upstream end of the second portion 34 of the Compressed gas channel is used.
  • the first filter element 38 prevents contamination or dirt particles when filling the compressed gas container into the compressed gas container be introduced.
  • the second filter element 36 prevents contamination or dirt particles get into the pressure control device 32.
  • Each of the Filter elements 36 and 38 can be metal fibers or balls or filter bodies made of ceramic Contain materials that withstand the mechanical stresses caused by the high pressure differences and withstand flow rates.
  • filter elements in gas pressure weapons is also involved a manually operated clamping lever for generating the compressed gas.
  • Can also Filter elements are also used in the context of the invention in such gas pressure weapons, where the compressed gas supply via a compressed gas hose directly from a compressed gas storage container he follows.
