Abstract

The cooled barrel for a rifle has central rifled bore and four longitudinal cooling external grooves enveloping the shrunk tube. The cooling grooves are equally spaced and cooling air is drawn into the barrel through a cartridge chamber and propellant residues burned. After machining of the barrel with its cartridge chamber, external longitudinal grooves are milled into the barrel. These grooves reach up to the start of the cartridge chamber. The cooling envelope tube is subsequently shrunk on the barrel. This shrunk envelope accommodates a clamping ring and the brackets for the foresight and the loading tube and the housing holders. The flash damper has four sloping bores cooling channels, and a central bore which expands forward.

Description

Selbstkühlrohr für Gewehr ###Self-cooling tube for rifle ###

Fertigung des Selbstkühlrohrs: Hauptteile: 1. Rohr (Laui) 2. Kühlmantelrohr 3. Feuerdämpfer 4. Haltering zu 1) In einen Laufrohling Kal. 7,62 mm wird ein Patronenlager angebracht mit 12 Entlastungsrillen für die Nato-Patrone 7,62 x 51. Nach Fertigstellung seiner Aussenabmessungen werden von vorne nach hinten bis zum Anfang des Patronenlagers aussen 4 Nuten im 90 Winkel zueinander eingefräst.Manufacture of the self-cooling pipe: Main parts: 1. Pipe (Laui) 2. Cooling jacket pipe 3. Fire damper 4. Retaining ring for 1) A cartridge chamber is inserted into a barrel blank, cal. 7.62 mm attached with 12 relief grooves for the Nato cartridge 7.62 x 51. After completion its external dimensions are from front to back to the beginning of the chamber 4 grooves milled on the outside at a 90 angle to each other.

zu 2) Als nächstes wird das Kühlmantelrohr über den Lauf aufgeschrumpft. Das Kühlmantelrohr erhält nun die Bearbeitungen für Aufnahme des Halterings, der Korn- und Laderohrhalterung sowie Gehäusehalterung und die 4 Bohrungen der Kühlkanäle.Regarding 2) Next, the cooling jacket tube is shrunk onto the barrel. The cooling jacket pipe now receives the processing for receiving the retaining ring, the Front sight and loading tube holder as well as housing holder and the 4 holes for the cooling channels.

Zum Schluss werden die Kühlrippen angebracht.Finally, the cooling fins are attached.

zu 3) In den Feuerdämpfer werden von hinten 4 schräg zur Mitte verlaufende Bohrungen (Kühlkanäle) gebohrt. Anschliessend wird durch die Mitte des Feuerdämpfers eine 8 mm # Bohrung angebracht, die sich vorne konisch erweitert. Die Feuerdämpfung und Gewehrgranathalterung wird G 3 - üblich ausgeführt. Zum Schluss werden nun die Kühlrippen und die Halteringaufnahme geiertigt.to 3) In the fire damper 4 diagonally to the middle are placed from the rear Bores (cooling channels) drilled. Then through the middle of the fire damper an 8 mm # hole is attached, which widens conically at the front. The fire suppression and rifle grenade holder is G 3 - customary. Finally, the Cooling fins and the retaining ring holder are closed.

zu 4) Der Haltering ist aus Federstahl und hält im Klammerverfahren Feuerdämpfer und Kühlmantelrohr zusammen und sichert sie gleiohzeitig gegen Verdrehen.Regarding 4) The retaining ring is made of spring steel and is held in place with a clamp Fire damper and cooling jacket pipe together and secure them against twisting at the same time.

Wirkungsweise: Selbstkühlrohr für Gew@nr.# # Die Kühlrippen vergrössern die Oberfläche und geben dadurch die Wärme besser an die Luft ab. Wird nun im Patronenlager eine Patrone gezündet, so schiebt das Geschoss die Luft im Lauf vor sich her. Diese stark komprimierte Luft saugt über die Kühlkanäle im Feuerdämpfer die kalte Luft nach. Die selbe Wirkung haben ebenso die stark komprimierten Pulvergase.Mode of operation: Self-cooling pipe for Gew@nr.# # Enlarge the cooling fins the surface and thereby better release the heat into the air. Is now in the chamber If a cartridge is ignited, the projectile pushes the air in the barrel in front of it. These strongly compressed air sucks the cold air through the cooling ducts in the fire damper after. The highly compressed powder gases also have the same effect.

Selbstkühlrohr und Feuerdämpfer zusammen erlauben durch das Kaltluftansaugsystem eine bessere Kühlung des Rohrs (Laufs).Self-cooling pipe and fire damper together allow through the cold air intake system better cooling of the tube (barrel).

Da nun die Kühlkanäle am Patronenlager die Kaltluft ansaugen, wird das Patronenlager sofort gekühlt. Die K@ltluft umspült vom Patronenlager bis zum Mündungsfeuerdämpfer in den 4 Kühlkanälen den Lauf. Da sich nun die Luft im Feuerdämpfer mit den Pulvergasen und brennenden Pulverrückständen mischt, erreicht man an der Mündung eine wesentlich schnellere Verbrennung der Pulverrückstände (kürzerer Lichtblitz).Since the cooling channels on the cartridge chamber now suck in the cold air, will the chamber immediately cooled. The cold air washes around from the cartridge chamber to the Flash hider in the 4 cooling channels the barrel. There is now the air in the fire damper mixed with the powder gases and burning powder residues can be reached at the Much faster combustion of the powder residues (shorter flash of light).

Das Selbstkühlrohr erlaubt die "theoretische Feuergeschwindigkeit" in eine "praktische Feuergeschwindigkeit" umzuwandeln.The self-cooling pipe allows the "theoretical rate of fire" to convert it into a "practical rate of fire".

Selbstfühlrehr für Gas Nr.# # Patentanspruch Als patentfähig soll unter Schutz gestelt n: Das Selbstkühlrehr, bestehend aus Rohr (Lauf) mit den 4 Kühlnuten und dem darübergezog an Kühlmantelrohr, dazu der Feuerdämpfer mit Seinen 4 Kühlkanalbohrungen. Self-feeler for gas No. # # Patent claim As patentable is supposed to under protection: the self-cooling tube, consisting of a tube (barrel) with the 4 Cooling grooves and the overlying cooling jacket pipe, plus the fire damper with its own 4 cooling duct bores. Selbstkühlrohr und Feuerdämpfer zusammen Erlenben durch das Kaltluftansaugsystem eine bessers Köhlung des Rohrs (Laufs). Self-cooling pipe and fire damper together Erlenben through the cold air intake system a better carbonization of the barrel (barrel). Der Feuerdämpfer mischt die Pulverrückstände mit der Kaltluft und bewirkt dadurch eine höhere Verbrennung der Restpulverrückstände. Hierdurch ergibt sich ein geringeres Mündungsfeuer tlrd geringere Rauchentwicl.lung. The fire damper mixes the powder residue with the cold air and this causes a higher incineration of the remaining powder residues. This results in A lower muzzle flash leads to lower smoke development.
