As seen from Fig. 1, the pipe 5 is supported in the Lich längsverschieb from the front inserted into the weapon housing 1 tubular sleeve with a gas piston 6 in the front region. The arranged between the inner wall of the gun housing 1 and the tube 5 or the gas piston part of the tubular sleeve with gas piston 6 tubular spring 10 exerts pressure on the back of the tubular sleeve part of the tubular sleeve with gas piston 6th Thus, the tube sleeve with gas piston 6 presses with its front side onto the rear of the weapon housing cover cap 2 , which is held there by its warts in the wart contact surfaces of the weapon housing 1 .

The front, under the weapon housing 1 and on its underside in longitudinally displaceably mounted in guideways, the loading / handle 19 is arranged. By pressing the pusher of the loading / handle 21 , the spring of the lever of the loading / handle 25 is loaded. The lever of the loading / handle 24 rotates about the axis of the loading / handle 23 and occurs with its rear, upward-pointing nose from the rest of the Waffenge housing 1st With the push button of the loading / handle 21 still operated, the loading / handle 19 can be moved forward parallel to the tube axis. After a short distance, the part of the loading / handle 19 , which previously rested in a recess at the bottom of the front of the weapon housing cover cap 2 , touches the rear of the muzzle brake 13 , which is attached to the mouth of the tube 5 and can be removed is. If this forward movement is continued, the loading / handle 19 takes the tube 5 forward under load on the tube spring 10 .

The part of the loading / handle 19 which is formed at the top and towards the rear is mounted in the piston body 11 so as to be longitudinally displaceable. It carries the pusher 26 rotatable about the axis of the fuse pusher 27, loaded by the spring of the fuse pusher 27 , pusher 28 . It is rotated during the forward movement of the loading / handle 19 , even before touching the muzzle brake 13 , by the bevel on the weapon housing 1 . The safety pusher 28 , which rests in the middle of the securing part of the trigger device 29 formed in the U-shape as seen from the front, with the part pointing downward, presses it downward into the trigger 31 under the load on the spring of the securing part of the trigger device 33 . In this case, the contact with the pulling fork 30 is removed and firing of a shot when the tube 5 is not present on the butt plate 4 is prevented.

The sliding lock that can be operated on both sides and is arranged above the handle on the piston body 11 has a sliding body holder 37 that is loaded about the axis of the sliding body holder 35 by the spring of the sliding body holder 36 , which is supported on the piston body 11 . This block, as shown, with its nose pointing downward at the front, the trigger 31 which is formed into a spur in the upper part towards the rear. If the H-shaped sliding body 34 , which is displaceable in the longitudinal direction in guideways in the piston body 11 , is pushed forward, the sliding body holder 37 comes out of the catch of the sliding body 34 with its nose.

He rotates about the axis of the sliding body holder 35 , relieving the spring of the sliding body holder 36 , and holds the sliding body 34 in the forward position. The weapon is now unlocked. The trigger 11 can be withdrawn.

Fig. 2 shows the tube-retaining lever 16 about the axis of the pipe holding lever 17, which is inserted through the housing of the piston body 11, rotatable and the charge / handle 19 is arranged above halfway. It is loaded by the spring of the pipe holding lever 18 , which is supported on the housing of the piston body 11 . His front, upward-pointing nose, which extends through an opening in the piston body 11 , in the weapon housing 1 and on the underside of the tubular sleeve 15 , holds the pin on the underside of the tube 5 and firmly connected to it. When the loading / handle 19 is advanced, the tube holding lever 16 , the rear part of which has hitherto rested in a recess of the loading / handle 19 , is rotated about the axis of the tube holding lever 16 by the spring of the tube holding lever 18 . The pin of the tube 5 is released. The loading / handle 19 together with the tube 5 can be pulled further forward.

The from the front, up to the stop at the constriction, insertable into the weapon housing 1 , hollow cylindrical tube sleeve 15 encloses the longitudinally movable tube 5 and is hollowed out in the inner region so far down that the pin of the tube 5 move therein can. The wound around the tube 5 , pressurized tube spring 10 , loads the tube ring 7 , which is firmly connected to the tube and at the same time the tube sleeve 15 on its back. It exerts with its front side by a pressure on the Waffengehäuseabdeckkappe 2, which is removably mounted to the front of the weapon housing 1, and thus holds them with their warts in warts contact surfaces of the weapon housing 1 fixed.

At the mouth of the tube 5 , the muzzle ring 12 is screwed on.

The lower shown in Fig. 3, formed rearward to a hollow cylinder part of the loading / handle 19 , which protrudes below the handle of the piston body 11 into the corresponding cavity of the piston body 11 and is guided longitudinally there, carries the tension spring of the load - / Handle 22 . It is suspended in the loading / handle 19 and the piston body. The tensile force of the tension spring of the loading / handle 22 is increased during the forward movement of the loading / handle 19 .

Fig. 4 illustrates the top of the tube 5 arranged radial bore 8 and the gas cylinder 9th

The left side of the sleeve ejection opening is covered by the holder 63 , which in its position above, through the two upper left side firmly connected to the wafer fengehäuse 1 hollow cylinder through which the stud screw of the sleeve ejector 62 is inserted and below by engaging in a groove in the piston body 11 , held. The sleeve ejector 65 , which is arranged rotatably about the stud of the sleeve ejector 61 , is loaded by the spring of the sleeve ejector 64 , which is supported on the holder 63 . The sleeve ejector 65 rests with its nem, protruding toward the inside, correspondingly shaped part on the outside of the tube 5 .

In the upper region of the piston body 11 , the trigger fork 30 is guided in a longitudinally displaceable manner in both-sided cavities.

The projection on the right-hand side in the piston body 11 holds the lamella with the strip 75 when the magazine 60 is inserted from below into the magazine shaft of the piston body 11 . When pushing the magazine 60 further up in the weapon until the magazine holder 56 engages in the catch of the magazine 60 , the upper plate 73 and the lower plate 74 movably connected to it are loaded under loading of the front plate spring 76 and the rear plate spring 77 , which in turn is movably connected to the slat with bar 75 , pulled downward in guideways which are arranged in the respective inner side of the front and rear walls of the magazine 60 . As a result, the feeder 79 can convey the ammunition 20 upwards through the opening now opened at the top of the magazine 60 .

As seen from Fig. 5, the pipe 5 in the front position. The loaded by the spring of the sleeve ejector 64 sleeve ejector 65 is blocked in its Drehbe movement around the stud of the sleeve ejector 61 by a catch on the top of the piston body 11 in the region of the sleeve ejection opening. It is formed inwardly protruding so that it only allows a partial rise of the ammunition 20 from the magazine 60 through the opening at the top of the piston body 11 and through the opening on the underside of the weapon housing 1 .

The tube 5 presses the sleeve ejector 65 in the backward movement, by relaxing the tube spring 10 , over its bevel arranged on the front inside, which is applied on both sides, front and rear, to the outside. The ammunition 20 rises. The tube 5 slips over the ammunition 20 during the further backward movement and comes to a standstill on the butt plate 4 . During the forward movement of the tube 5 , with the start of the beveling of the sleeve ejector 65, this, while releasing the spring of the sleeve ejector 64 , is rotated inward by the stud of the sleeve ejector 61 until the sleeve ejector 65 is blocked in its movement by the catch in the piston body 11 . By this Drehbe movement of the sleeve ejector 65 , the sleeve of the ammunition 20 or the non-fired ammunition 20 is ejected to the right. At the same time, the sleeve ejector 65 prevents the ammunition 20 from rising and thus the magazine 60 from being emptied independently.

For left-handed shooters, the sleeve ejection device, which includes the stud of the sleeve ejector 61, the nut of the sleeve ejector 62 , the holder 63, the spring of the sleeve ejector 64 and the sleeve ejector 65 , can be implemented on the opposite side of the wafer fengehäuses 1 .

The Fig. 6 reveals the insertable from above into the piston body 11. Piston cap 14. It is T-shaped on the inside. The inwardly bent parts on both sides at the rear end of the piston body 11 engage laterally in the piston cap 14 and hold it in place.

In Fig. 7 is arranged in the rear lower region of the piston body 11 , rotatable about the axis of the magazine holder 55 magazine holder 56 Darge provides. The lower part of the magazine holder 56 partially protrudes into a cavity in the piston body 11 , which is arranged behind the rear wall of the magazine shaft and on the underside of the piston body 11 . The spring of the piston cap holder 59 is supported on the housing of the piston body 11 and loads the piston cap holder 58 which is displaceable in the longitudinal direction in the piston body 11 via its downward-pointing pin. It is fork-shaped in its front area and ends with a hole. The inserted through these two holes axis of the piston cap holder 57 is guided in an elongated hole in the lower part of the magazine holder 56 . The piston cap holder 58 loaded by the spring of the piston cap holder 59 transmits this force to the magazine holder 56 . This is when not actuated with its upper part on the rear wall of the magazine shaft, while at the same time its upper end, which is shaped to a front-facing nose, engages through an opening in the rear wall of the magazine shaft into a catch of the inserted magazine 60 and holds it there . Likewise, the piston cap 14 inserted from above is locked by engagement of the piston cap holder 58 in the catch of the piston cap 14 .

Fig. 8 shows the percussion device. It is inserted from behind in guideways of the piston body 11 , which are arranged on its inside, up to the back of the inner wall of the piston body 11 . The front of the inner wall of the piston body 11 contacts the back of the breech 4, which is rigidly connected to the weapon housing 1 when assembled weapon.

The butt plate 4 , the inner wall of the piston body 11 and the front wall of the impact housing 38 are provided with four openings, each in the longitudinal direction.

In the upper opening and in the hole behind it in the intermediate wall of the striker housing 38 , the striker slide 40 is guided in a longitudinally movable manner. In the striker housing 38 under the striker slide 40 , the spring of the striker slide 39 is in a parallel tube that connects the rear wall and the intermediate wall of the striker housing 38 leads GE. It is supported on the inside of the rear wall of the striker housing 38 , reaches through the opening in the intermediate wall in front of it and loads the part of the striker slide 40 pointing downward. This carries the vertically movable striker 42 loaded by the spring of the striker 41 . It is formed laterally to a transverse axis which is guided in an opening created on both sides in the striking housing 38 . The longitudinally displaceable striking piece 44 , which is loaded by the striking spring 43 , is arranged underneath in the firing axis, behind the central opening. Below and rotatable about the axis of the striker holder 45 inserted through the striker housing 38 , the striker holder 47 is applied. It is loaded by the spring of the hammer holder 46 . With its nose pointing upwards, it engages in the catch arranged on the underside of the striking piece 44 and thereby holds it in place, while with the underside of the rear half it touches the trigger axis 49 , which can be moved longitudinally and on both sides in an elongated hole in the striking housing 38 . It is loaded by the spring of the trigger axis 48 , which is supported on the inside of the rear wall of the Schlagge housing 38 . In the lower front loading area of the impact device, the sleeve holder device is arranged. The rear end of the sleeve holder 52 is formed into a transverse axis and inserted into a corresponding holder in the impact housing 38 . The sleeve holder spring 51 is supported on the bottom of the impact housing 38 and loads the sleeve holder 52 , which engages through the lower opening. It holds the sleeve with its front end, which is shaped upwards towards a nose. He touches the top of the opening with his top.

If the trigger 31 is withdrawn, the trigger fork 30 , which is displaceable in the longitudinal direction in guideways of the piston body 11, performs the same movement. Your two parts are firmly connected to each other in the rear end area and angled upwards. You must be pushed from behind into the piston body 11 before the impact device is inserted. When the weapon is assembled, the trigger fork 30 engages around the underside of the striker housing 38 . The pressure of the spring of the trigger axis 48 , which is exerted on the trigger axis 49 on the two parts parallel to the sides of the striker housing 38 projecting parts of the trigger fork 30 , helps to keep the trigger 31 in the front position. The spring of the trigger axis 48 is loaded by the backward movement of the trigger fork 30 . The trigger axis 49 rotates the striker holder 47 about the axis of the striker holder 45 , under load of the spring of the striker holder 46 , from the catch of the striker 44 . This flaps forward relieving the striker spring 43 and fires the ammunition 20 . The tube 5 moves forward. The sleeve ejection device conveys the empty sleeve out of the weapon. The percussion slide 40 makes the forward movement of the tube 5 , relieving the spring of the percussion slide 39 , until its downward-facing part strikes the rear of the front wall of the percussion housing 38 . The striker tensioner 42 is forcibly guided over its transverse axis and the spring of the striker tensioner 41 , in the two openings laterally created in the striking housing 38 . Relaxing the spring of the striker 41 , the striker 42 , which is bevelled from the bottom to the top, slides down the ramp. It then meets the chamfer on the top of the striking piece 44 in the front position, is thereby pushed up, snaps down shortly before the striking slide 40 has reached its front position, into a catch on the top of the striking piece 44 . When the tube 5 moves backwards, it slips over the ammunition 20 and takes it with it. The tube 5 has an incision at the bottom on the bottom. By sliding back the tube 5 with the ammunition 20 located in the cartridge chamber, the sleeve holder 52 is rotated downward by the ammunition 20 against the pressure of the spring of the sleeve holder 51 . The sleeve holder 52 , which reaches through the incision of the tube 5 , snaps up again and thereby holds the ammunition 20 shortly before the backward movement of the tube 5 has ended. During this sliding back, the tube also pushes the striking piece slide 40 back. The hammer tensioner 40 takes the hammer 44 with it. The nose of the striker holder 47 pointing upward slides along the underside of the striker 44 and snaps into the catch on the underside of the striker 44 . In the final phase of the return of the pipe 5 , the striker clamp 42 has hit the ramp and has been pushed up as the pipe movement continues. As a result, his move from the rest of the striking piece 44 has been initiated. When the tube 5 bears against the butt plate 4 , this process is ended and the striker 44 is completely released. In the event of continuous fire, the trigger 31 is not released, so the striker holder 47 does not engage in the corresponding catch of the striker 44 . The striking piece 44 therefore rushes forward again and fires the ammunition 20 .

Between the breakthrough for the sleeve holder 52 and the breakthrough for the striker 44 , the breakthrough for the rod of the cartridge indicator 50 is arranged. It is double angled and is longitudinally displaceable through a hole in the intermediate wall and a larger hole in the rear wall of the housing 38 Schlagge. Its rear end protrudes beyond the rear wall of the impact housing 38 and is provided with a thread on which the cap of the cartridge indicator 54 is screwed on. The cap of the cartridge indicator 54 protrudes into a recess on the rear of the piston cap 14 . It is held in place by him and the piston cap holder 58 . The piston cap 11 is formed at the top, towards the front, to a downward-pointing pin which engages through an opening in the weapon housing 1 in a hole in the top of the striker housing 38 and thus holds the wafer housing 1 , the piston body 14 and the striker housing 38 together. If the weapon is not loaded, the spring of the cartridge indicator 53 pushes the rod of the cartridge indicator 50 forward so far that the angled parts of the rod of the cartridge indicator 50 touch the rear sides of the front wall and the intermediate wall of the striker housing 38 and the cap of the cartridge indicator 54 no longer in the recess of the piston cap 14 protrudes. This makes the gun's charge level visible and palpable. When dismantling the weapon, the rod of the cartridge indicator 50 is first pushed back and the cap of the cartridge indicator 54 , which has a thread at the front on the outside, is unscrewed. It turns into the counter thread of the piston cap 14 , which is created in the front region of the hole in the piston cap 14 . The cap of the cartridge indicator 54 is not lost as a result. After releasing the rod of the cartridge indicator 50 , the piston cap 14 can be pulled upwards.

In Fig. 9 the ver with the weapon housing 1 connected handle 66 is illustrated. The head visor 69 is arranged in the upper U-shaped part of the handle 66 . It is rotatably mounted about the axis of the guide sight 67 , which is inserted transversely through the handle 66 . Due to the pressure of the spring of the head sight 68 , the head sight 69 is held in a tube-parallel position and rests in the U-shaped part of the handle 66 . The front end of the lead visor 69 is formed into a combat visor so that it can be struck over a known distance without manipulating the visor. The front support of the handle 66 is provided with an opening. The middle part of the visor trigger bar 70 projects into this from below. It is rotatably mounted about the axis of the visor trigger bar 72 , which is inserted transversely through the handle 66 . The spring of the visor trigger bar 71 is supported on the weapon housing 1 and loads the visor trigger bar 70 via its rear part. Her upward rotational movement is limited by the housing of the support of the handle 66 .

The rear support of the handle 66 is grooved in the upper area on the back. From this point, the head visor 69 can be rotated about the axis of the head visor 67 , under the load of the spring of the head visor 69 , until it stops against the inner wall of the front support of the handle 66 . After releasing the head visor 69 , it rotates back a little until its front end is held in the catch of the visor trigger bar 70 , which is placed in the front part of the visor trigger bar 70 . In this case, the visor pusher bar 69 rotated downwards by the front end of the head visor 69 , against the pressure of the spring of the visor pusher bar 71 , has returned to its starting position. By pressing the visor trigger bar 70 downward, the guide visor 69 comes out of the latch of the visor trigger bar 70 and rotates back into its rest position, relieving the spring of the guide visor 68 .

Furthermore, the gun housing ring 3 which is fixedly connected to the weapon housing 1 can be seen in FIG. 9. It serves as an abutment surface of the tube ring 7 connected to the tube 5 , which is loaded by the tube spring 10 . In addition, the barrel 5 , together with the gas cylinder 9 , which is fixedly connected to the barrel 5 on the top of the barrel, is mounted in a longitudinally displaceable manner in the weapon housing ring 3 . The radial bore 8 towards the top of the tube 5 opens into the gas cylinder 9 . It is arranged directly in front of the case edge of the ammunition 20 . After the ammunition 20 has fired, the combustion gases drive the projectile past the radial bore 8 through the tube 5 . The gases who pressed the through the radial bore 8 in the gas cylinder 9 . They act in the gas cylinder 9 against the forward movement of the tube 5, which has strive by the friction of the projectile on the inner wall of the tube 5, the loading, to be pulled forward by with. As long as the projectile is in the tube 5 , there is an overpressure in the gas cylinder 9 , which delays the advance of the tube 5 . After the projectile has left tube 5 , the gas pressure drops rapidly, and the gases that previously flowed into gas cylinder 9 now push back. This opens the shutter, the gases hit the muzzle brake 13 and pull the pipe 5 forward. After the tube 5 has reversed, the tube spring 10 presses the tube 5 back into its starting position. The advantage of the unlocked gas-delayed mass lock is that it easily adapts to ammunition 20 different laboratory.

The magazine 60 not inserted into the weapon is shown in FIG. 10 and in FIG. 11. It contains two rows of ammunition 20 . The upper lamella 73 is movable with the lower lamella 74 and this in turn is movable with the lamella with ledge 75 . They are movably supported in guideways on the inside of the front and the inside of the back of the magazine 60 . A front plate spring 76 and a rear plate spring 77 , which are supported on the housing of the magazine 60 , load the plate with bar 75 . This presses over the lower lamella 74, the upper lamella 73 , up to the limits of the guideway created on both sides in the magazine 60 , upward. As a result, the opening at the top of the magazine 60 is closed to such an extent that the ammunition 20 , which is pushed by the feeder 79 , which is loaded by the feeder spring 78 and pushed upwards, cannot leave the magazine 60 . The feeder 79 is guided in a vertically displaceable manner in the magazine 60 on the inside of the front and rear walls of the magazine 60 and additionally in recesses which are created in the front and rear walls of the magazine 60 . The feeder 79 is extended upwards on its front side, so that this part protrudes when the magazine 60 is shot through the perforated upper side of the front wall of the magazine 60 , blocks the return of the tube 5 and thus indicates to the shooter that the magazine 60 is empty is. Through the rear wall of the magazine 60 closed at the top, the feeder 79 is prevented from climbing further. On the outside of the rear wall of the cartridge 60 a locking is applied, the magazine holder 60 engages with an inserted 56 into the magazine.

Fig. 12 shows the muzzle brake 13 , which is used only in the embodiment of the weapon with gas-delayed mass closure, instead of the muzzle ring 12 , Ver. It is designed in the application form shown as a muzzle brake and screwed to the pipe mouth.

As can be seen from Fig. 13, the front area of the weapon by extending the weapon housing cover 2 , the piston body 11 and the loading / handle 19 , as far forward, until the rear part of the muzzle brake 13 is slightly enclosed, as further possible Design shown.
