Definitions
- the invention relates to a gas pressure loading self-loading rifle, with a gas cylinder passing through one end Floor is closed and encloses a gas chamber that through a gas channel at a tap point with the Run hole is connected, and with a gas piston, which in the other end of the gas cylinder between a rest position, in which it determines the smallest volume of the gas chamber, and an end position, in which he has the largest volume of the gas chamber specifies is slidably arranged.
- Such a generic self-loading rifle is from the DE 721 591 known.
- the bullet When the shot is fired, the bullet passes through a hole that forms the mouth of the extraction channel, after which high tension Powder gases penetrate into the gas chamber and energetically Drive the gas piston from its rest position to an end position.
- the Gas pistons in turn act on movable functional parts which, after a movement cycle is covered by a Return spring must be pressed against the gas piston again and spend it from its end position to its rest position.
- Gas cylinders and gas pistons are relatively long, so that Adequate sealing around the piston occurs when this is performed with a larger game is.
- the piston length must be greater with higher clearance otherwise, the gas outlet to the rear are the functional mechanisms the weapon and thus its function-inhibiting Pollution too high. Growing up with the longer piston length but constructive problems because the total length of the The weapon should be as small as possible, and the tapping point on the barrel is determined by its inside ballistics.
- a gas leak to the rear means one larger amount of gas conveyed by the device and thus also higher pollution.
- the aim of the invention is the known gas cylinder gas piston device in this regard to further educate them at least of the above problems partially overcome.
- a single piston ring can be sufficient. It is preferred to provide multiple piston rings to the Cleaning and sealing function still to be improved (claim 2). Deposits not from the foremost piston ring were removed but scraped off by a subsequent one only form a small amount and can settle between the piston rings without their effect affect.
- the piston rings can run the entire length of the piston be distributed, but are preferably close to each other and form a band-like piston ring arrangement (claim 3). Their distance is preferably determined so that when the Piston rings start to vibrate when the piston moves should be the chatter marks caused by each one cover each other so that all deposits are completely be eliminated.
- the piston rings can face the inner wall of the gas cylinder have a slight play, which then reduced in size due to smoke deposits and completely cancels.
- the piston rings are preferably located under tension against the inner wall of the gas cylinder (Claim 4), so that on the one hand on this inner wall can not form any deposits, on the other hand the desired sealing guaranteed from the first shot is.
- the piston ring arrangement can approximately in the longitudinal center of the Pistons can be arranged, or the piston rings can over the length of the piston should be distributed around it evenly support.
- the invention is the piston ring or the piston ring arrangement near the front end of the gas chamber Piston arranged (claim 5). Even when delivering several thousand shots without oiling or cleaning the gas cylinder gas piston device can the deposits that build up then formed in the gas chamber, the movement of the Do not affect the piston because the area of the cylinder bore, in which the piston is located, through which Always keep the piston ring or piston ring assembly clean remains.
- the gas chamber can be relieved of pressure the gas channel to the bore hole. It is also possible, a gas outlet opening in the cylinder inner wall to be provided, which is released by the piston when it is is in its final position. After all, one could Open the gas outlet directly into the gas chamber, however, an adjustment device is required to to prevent so much gas from escaping that the function the gas piston is no longer reliably guaranteed. at this adjustment device is increasing pollution readjust if necessary.
- the gas piston has an axial extension with a smaller diameter on its end face facing the gas chamber, which is designed as a control pin and passes through an opening in the bottom of the gas cylinder with little play when the gas piston is at rest ( Claim 6).
- the advantage of this design is that when the piston is accelerated sufficiently, a large gas outlet opening is opened into the gas chamber, so that the gas pressure then drops rapidly.
- the inside surface of the gas cylinder is therefore only exposed to the deposited powder gases for as short a time as possible.
- the gas escapes at the point of the gas chamber furthest away from the piston, so that gases which are not in it still run the risk of being flushed around the piston when it emerges.
- the opening in the floor can go directly into the ambient air open out; however, a relaxation chamber is preferred arranged, which in turn opens into an outlet nozzle (Claim 7).
- a relaxation chamber is preferred arranged, which in turn opens into an outlet nozzle (Claim 7).
- Is preferred between the end face of the gas piston and the trunnion has a truncated cone-shaped transition (Claim 8) of not only the strength of the control pin improved, but the hot powder gases from the gap between derives the gas piston and the inner wall of the gas cylinder.
- a Conventional attachment piece provided that the gas channel and forms the gas cylinder.
- the barrel passes through a hole of this attachment piece. To hold a reliable To ensure such attachment piece, it is usually shrunk onto the barrel.
- the attachment piece not shrunk on the barrel, just pushed on.
- a cross hole is through to the barrel and to the attachment this continuously trained that the barrel still is cut.
- this cross hole there is an adapter sleeve indented, which resiliently tight against the inner surface the cross hole creates and thereby the tight fit of the Top piece guaranteed.
- An adapter sleeve is understood to be a longitudinally slotted tube Spring steel that is oversized or pressed into a hole - is struck and compressed resiliently.
- the clamping effect that is exerted on the adapter sleeve becomes increased by preferred training (claim 10), according to which the barrel is cut into the cross hole protrudes in the attachment piece; the opposite one Part of the cross hole can be left blank.
- the Is the axis of the clamping sleeve pressed into the transverse bore therefore not straight, but slightly curved.
- the arrow points in the direction of the mouth and defines the Location information "front”, “back”, etc .; if one of the in gun stops horizontal, then the positions "top”, “bottom” etc. correspond to the drawing.
- a barrel 1 has a bore 7 and an outer, cylindrical Section (no reference symbol). Run 1 has a smaller one in front of the cylindrical section Diameter on than this, behind the cylindrical Section a larger diameter.
- the running wall is in the area of the cylindrical section through a tap hole extending radially upwards 5 enforced.
- a hand guard 3 has the shape of a perforated housing and encompasses the barrel 1 at a distance.
- the said cylindrical Section with the tap hole 5 is in the front end area of the hand protection 3.
- This attachment piece 9 On the cylindrical portion of the barrel 1 is a Attachment piece 9 pushed on appropriately.
- This attachment piece 9 has a blind hole that is open to the rear and parallel to the barrel on, which forms a gas cylinder 15. Its floor 17 is penetrated by a hole which an opening 19 in Floor 17 forms and in front of this an elongated relaxation room 21 defines, the front end of which is conical tapers and into an outlet nozzle 23 open to the outside opens.
- the Hand protection 3 At a distance from the outlet nozzle 23, the Hand protection 3 an opening penetrated by barrel 1 (no Reference numerals), whose upper edge is approximately at the level of Outlet nozzle 23 is located. Above the opening, it is the Inner wall of the hand protection 3 bevelled upwards and backwards and thus forms a baffle for exiting Gas.
- the front part of the gas cylinder 15 forms a gas chamber 33.
- One goes radially downward from this gas chamber 33 Small diameter hole from which the attachment piece 9 enforced, meets the tap hole 5 and one has a larger diameter than this.
- the diameter of the Opening 19 is still larger than the diameter of the gas channel 35.
- the diameter of the outlet nozzle 23 corresponds approximately to that the tap hole 5.
- a gas piston 25 is displaceable in the gas cylinder 15 used, the one on its front face forward-tapering frustoconical transition 27 is extended, which is coaxially with the gas piston 25 extending cylindrical control pin 29 passes.
- the Control pin 29 has a diameter that is a little is smaller than the diameter of the opening 19 in the bottom 17th
- the gas piston 25 is in the gas cylinder 15 with little play guided and points near its front edge, where its cylindrical Section on the frustoconical transition 27 hits, a ribbon-shaped arrangement of three with little Distance adjacent piston rings 31.
- the Piston rings 31 are resiliently biased against the Inner wall of the gas cylinder 15. Since the piston rings 31 for the assembly will have an open position, three rings assembled one behind the other and arranged rotated against each other; this ensures that the entire diameter is always is sealed.
- the gas piston 25 is around a guide shoulder 37 extended, in the hole open to the rear a push rod 39 is received, which the piston movement backwards on a fastener carrier, a fastener or transmits a locking device (not shown).
- This piston ring 31 consists essentially of a circular spring steel bracket, which is a rectangular Has cross-section.
- the spring steel bracket extends not over the full extent, but saves a division joint 33 out.
- piston ring 31 does not have the continuous same width - in the top view of FIG. 2 seen - but is the parting line 33 opposite widest, on both sides of the parting line 33 close to this narrowest and has two final thickenings that the Flank joint 33.

Description
Der Vorteil dieser Ausbildung ist es, daß dann, wenn der Kolben ausreichend beschleunigt ist, eine große Gasauslaßöffnung in die Gaskammer hinein geöffnet wird, so daß dann der Gasdruck rasch abfällt. Die Innenoberfläche des Gaszylinders wird deshalb den sich ablagernden Pulvergasen nur so kurz wie möglich ausgesetzt. Außerdem erfolgt der Gasaustritt an der vom Kolben am weitesten entfernten Stelle der Gaskammer, so daß nicht in dieser befindliche Gase beim Austritt noch Gefahr laufen, den Kolben ablagernd zu umspülen.
