Definitions

  • the invention relates to a firearm with a gas drive for the shot-dependent actuation of a loading and / or firing device, the gas drive or the like from a bundle.
  • the barrel itself as a gas piston and a barrel sleeve extending over the collar as a gas cylinder and the barrel sleeve can be displaced against the barrel against the force of a return spring by means of powder gas acting on its cylinder space connected to the barrel core via at least one transverse bore, the barrel sleeve being directly one with one Loading - and taking along with a launching device interacting slide.
  • a firearm is known from US-A-3,261,264.
  • a drive option In order to be able to partially or completely automate a firearm, a drive option must be provided for individual steps of the loading and unloading process or for the entire charging and ignition process, and gas drives for using the residual energy still present in the powder gases after the firing of the shot have proven to be a suitable drive source already proven.
  • the gas drives consist of their own piston-cylinder units separate from the barrel, the cylinders being firmly connected to the barrel or the housing and the movable reciprocating piston or the like, the corresponding parts of the loading and / or launching device via a piston rod. operated.
  • These piston-cylinder units comprise a large number of expensive components and therefore require a considerable amount of construction, they take up a lot of valuable space and also bring about a corresponding increase in the weight of the weapon.
  • the invention is therefore based on the object to eliminate these deficiencies and to provide a firearm of the type described, which is characterized by a particularly simple and reliable, light and space-saving construction of its gas drive.
  • the invention solves this problem in that the barrel has annular grooves in the entire displacement area of the barrel sleeve and the end stop opposite the collar is designed to be resilient for the barrel sleeve.
  • the ring grooves according to the invention in the sliding area of the barrel not only result in a labyrinth direction which reduces the risk of contamination, but they also allow a drive which acts over the entire return of the barrel, which is in contrast to the known gas drives, which always act only in pulses. There is a corresponding drive power, so that in order to dampen the impact of the sleeve at the end stop this advantageous manner is resilient.
  • the resilient end stop additionally reinforces the effect of the return spring, which plays an important role especially in the reversing area.
  • a bush enclosing the barrel is used as the end stop, which is supported axially on the housing receiving the barrel and is provided with transverse slots in the freely projecting stop end, this results in a simple construction for the end stop, which also obtains a desired stiff spring characteristic.
  • An indicated firearm 1 consists essentially of a housing 2, a barrel 3 and a loading and firing device 4 with trigger 5.
  • a sliding piece 6 is provided which is displaceable in the barrel direction and which is operated by a gas drive 7 is moved depending on the shot.
  • the gas drive 7 consists of a collar 8 of the barrel 3 serving as a gas piston and a barrel sleeve 9 forming the associated gas cylinder, which extends over the collar 8 and sits longitudinally displaceably on the barrel 3.
  • the cylinder space 11 between the collar 8 and the sliding seat 9a of the barrel 9, which is adapted to the barrel 3, is connected to the barrel core and can therefore be charged with powder gases via this transverse bore 10 after a shot has been fired.
  • annular grooves 3a and 8b are provided in the barrel 3 or collar 8 in the displacement area of the barrel sleeve 9.
  • the sleeve 9 is displaceable against the force of a return spring 12 by applying gas to the cylinder space 11, an end stop 13 limiting the displacement movement of the sleeve 9.
  • the slider 6 engages with a driving sleeve 16 connected to the running sleeve 9, so that the displacement movement of the running sleeve 9 is transmitted directly to the slider 6 and the loading and Launcher 4 is operated.
  • powder gases pass through the transverse bore into the cylinder chamber 11 and, due to this gas application, the barrel sleeve 9 is moved against the end stop 13.
  • the return spring 12 throws the barrel sleeve 9 back immediately, the buffer spring created by the transverse slots 15 in the stop end 14a on the one hand damping the impact of the barrel sleeve 9 on the end stop 13 and on the other hand accelerating the reversal of movement. If, however, the trigger 5 is released after the shot is broken, the trigger in the exemplary embodiment shown catches the slide 6 in the extended position (FIG. 2) and interrupts the sequence of movements, which in contrast to the continuous fire single trigger is allowed when trigger 5 is pulled.
