Definitions

  • the present invention relates to an automatic, gas-pressure-operated handgun according to the preamble of independent claim 1.
  • Such a delay space can fill up with a considerable amount of powder residues over time and although the channel is cleaned at least in the piston by the gas passage on both sides, the channel from the barrel to the cylinder can be clogged with residues.
  • the gas pressure loss due to the large delay space can cause a significant loss.
  • 1 and 2 show a section of the weapon with the piston in two different operating positions.
  • the barrel 1 is provided in the front part near its mouth with a radial bore 14.
  • the trains with the grooves 13 and the raised areas 12 are visible in the course.
  • a nozzle piece 2 serves as a grain carrier, which is not shown, however, because it is generally known.
  • the nozzle piece 2 has a bore parallel to the barrel 1, into which a cylinder consisting of cylinder tube 50 and insert sleeve 22, which also forms the cylinder base 18, is inserted.
  • the nozzle piece 2 is secured by means of pins 15 against rotation relative to the barrel 1.
  • the nozzle piece 2 Aligned with the bore 14 in the barrel, the nozzle piece 2 has a bore 21 and the cylinder tube has a bore 26, which together with the bore 14 form an inlet channel to the cylinder.
  • the insert sleeve 22 is provided with a laterally radially projecting flange 24 which is rotatably supported and guided in a groove section 52 in a cylinder flange 51 at the end of the cylinder tube 50.
  • the insert sleeve 22 carries on its part protruding from the cylinder tube 50 an adjustment knob 30 which has two side surfaces 30b arranged parallel to one another and a border 30a on the remaining circumference. On the face side, the adjusting knob 30 has a slot 30c for a screwdriver.
  • the insert sleeve 22 can thus be adjusted from the outside relative to the cylinder tube 50.
  • an adjusting screw 32 which is screwed into a thread 33 in the cylinder tube 50, the insert sleeve 22 can be held in two positions designated by markings 31.
  • the insert sleeve 22 has two radial bores 16, 17 of different diameters, the bore 16 being larger than the bore 17.
  • the nozzle piece 2 there are two bores 19, 20 which are located on the side of the Guide barrel 1 into the open and its axes lie in the same plane perpendicular to the barrel axis and intersect at least approximately at the point of intersection of the cylinder tube axis with said vertical plane.
  • the axes of the bores 16 and 17 in the insert sleeve 22 likewise intersect, at least approximately, at the point of intersection of the cylinder tube axis through said vertical plane.
  • the angle between the two axes of the bores 16 and 17 in the insert sleeve 22 is half as large as the angle between the two axes of the bores 19, 20 in the nozzle piece 2.
  • a piston 42 is inserted so as to be axially movable, which is rigidly connected to a piston rod 45 in order to transmit the movement of the piston 42 in the usual manner to the closure or to elements of the closure .
  • This piston is provided with a radial bore 28 which, in the operating position according to FIGS. 1 and 3, is aligned with the inlet channel formed by the bores 14, 21, 26 and 17.
  • An axial bore 29 in the piston 42 opens into the cylinder space 23 with the opening 41 in the piston head 40.
  • the cylinder tube 50 has three bores 25, 26, 27, the axes of which also lie in the same vertical plane on the axis of the barrel 1 and intersect at least approximately at the point of intersection of the cylinder tube axis through this plane.
  • the axes of two adjacent bores 25, 26 and 26, 27 enclose the same angles, which are incidentally the same size as the angles between the axes of the bores 16 and 17 in the insert sleeve 22. Accordingly, the axes of the two outer ones intersect Bores 25, 27 at the same angle as the axes of the bores 19, 20 in the nozzle piece 2.
  • the bores 14, 21, 26, 16 or 17, 28 and 29 together form an inlet channel into the cylinder space 23. Accordingly, the bores 16, 26 and 19 form a first outlet channel or the bores 17, 27 and 20 form a second outlet channel, when the insert sleeve is turned counter-clockwise from mark II to mark I.
  • the gas pressure driving the cartridge through the barrel from the combustion of the propellant powder passes behind the cartridge through bore 14 in barrel 1 according to arrow A in FIGS. 1 and 3 through bore 21 into nozzle piece 2 and further through bore 26 and 17 into the radial bore 28 in the piston 42.
  • the gas leaves the piston 42 through the axial bore 29 and generates a pressing pressure in the cylinder space 23, by means of which the piston 42 is displaced to the right in FIG. 1.
  • the gas flow is interrupted.
  • the inlet duct with the bores 14, 21, 26 and 17 and the outlet duct with the bores 16, 25 and 19 are connected to one another via the cylinder space 23, so that the strained gases in the cylinder space 23 In the direction of arrow C, flow out into the open and at the same time clean the bore 16 in the insert sleeve 22.
  • the arrow C is shown in broken lines because in the position of the piston 42 shown in FIG. 3, this channel is closed.
  • the insert sleeve 22 is arranged with the smaller bore 17 in the inlet channel and with the larger bore 16 in the outlet channel. This position is preferable for freshly cleaned weapons. If the insert sleeve is then rotated into position II, the larger bore 16 lies in the inlet channel and instead the smaller bore 17 in the outlet channel, as is clearly shown in FIGS. 2 and 4. In this way, a larger amount of gas is introduced into the cylinder space 23, which can release a larger opening energy onto a possibly very dirty closure system. The gas flow is also illustrated in FIG. 4 by the arrows A, B, D.
  • the closing spring on the piston rod 45 serves to return the piston 42 to the rest position.
  • the piston closes the outlet channel, the remaining gas from the cylinder chamber is pressed back into the barrel via the inflow channel.
