Pri tem je po izumu predvideno, da omenjena priprava za polnjenje rezervoarja stisnjenega pogonskega sredstva pri strelnem orožju, katerega izstrelek je gnan z omenjenim pogonskim sredstvom, obsega vsaj eno tlačno sredstvo, ki sestoji iz primarnega tlačnega valja, v katerega se po dovodnem vodu z vgrajenim protipovratnim ventilom dovaja medij, ki se ga stiska, in le-temu zaporedno prigrajenega sekundarnega tlačnega valja, iz katerega se po odvodnem vodu z vgrajenim protipovratnim ventilom odvaja stisnjeni medij. Omenjena tlačna valja pri tem obsegata isto cevasto batnico, ki na mestu povezave omenjenih tlačnih valjev brez tesnjenja prehaja iz prvega tlačnega valja v drugega. V primarni tlačni valj segajočemu prostemu koncu omenjene cevaste batnice je prigrajen primarni bat, medtem ko je v sekundami tlačni valj segajočemu koncu omenjene cevaste batnice prigrajen sekundami bat. Po izumu je predvideno, da je v področju med omenjenima batoma s pomočjo prezračevalne luknje v primarnem tlačnem valju zagotovljen okoliški tlak, medtem ko je v območju vsakokratnega prostega konca batov predvidena tlačna komora.The task according to the invention is solved by the characteristics given in the characteristic part of claim 1. According to the invention, it is provided that said device for filling a compressed propellant tank in a firearm whose projectile is driven by said propellant comprises at least one pressure means, consisting of a primary pressure cylinder into which a downstream conduit is mounted the non-return valves supply the compressible medium and the secondary pressure roller, which is sequentially mounted, from which the compressed medium is discharged through the drain line with the non-return valve. Said pressure cylinders herewith comprise the same tubular piston which, at the point of connection of said pressure cylinders, passes from the first pressure cylinder to the other without sealing. A primary piston is mounted in the primary pressure cylinder of the extending free end of said tubular piston, while in seconds the pressure piston is secured to the extending end of said tubular piston. According to the invention, it is envisaged that in the area between said pistons, a pressure chamber is provided in the primary pressure cylinder by means of a ventilation hole, while a pressure chamber is provided in the area of each free end of the pistons.

Izum je v nadaljevanju podrobneje opisan na osnovi izvedbenega primera in s sklicevanjem na priloženo skico, kjer je shematsko prikazana priprava za polnjenje rezervoarja stisnjenega pogonskega sredstva pri strelnem orožju po izumu.The invention will now be described in more detail based on an embodiment and with reference to the accompanying drawing, which schematically shows a device for filling a tank of compressed propellant in a firearm according to the invention.

Priprava za polnjenje rezervoarja stisnjenega pogonskega sredstva pri strelnem orožju po izumu sestoji iz vsaj enega tlačnega sredstva 1, ki obsega par medsebojno v smeri gibanja batov sklopljenih tlačnih valjev, namreč primarnega tlačnega valja 2 in sekundarnega tlačnega valja 3. Pri tem je po izumu predvideno, da oba tlačna valja 2, 3 obsegata isto cevasto batnico 4, ki na mestu 4a povezave obeh tlačnih valjev 2, 3 brez tesnjenja prehaja iz prvega tlačnega valja v drugega. Vsakokratnemu prostemu koncu omenjene cevaste batnice 4 je prigrajen po en bat, namreč primarni bat 5, razporejen v primarnem tlačnem valju 2, in sekundami bat 6, razporejen v sekundarnem tlačnem valju 3. Pri opisanem izvedbenem primeru je primarni bat 5, in s tem primarni tlačni valj, večjega premera od sekundarnega bata 6. Omenjena cevasta batnica 4 na strani primarnega bata 5 predira le-tega, tako da na strani, obrnjeni proč od sekundarnega tlačnega valja 3, štrli iz ravnine primarnega bata 5. Omenjeni štrlini 7 cevaste batnice 4, katera se vedno nahaja le znotraj tlačnega valja 2, 3, je prigrajen osni podaljšek 8, katerega prosti konec vedno štrli iz primarnega tlačnega valja 2 in mu je prigrajen neprikazan pogonski mehanizem, s pomočjo katerega se omenjeno batnico 4 in s tem omenjena bata 5, 6 premika v osni smeri omenjenega tlačnega sredstva 1. Omenjena štrlina 7 cevaste batnice 4 je pri tem zasnovana s prečno skoznjo luknjo 9, ki omogoča fluidno povezavo notranjosti cevaste batnice 4 s tlačno komoro 10 primarnega tlačnega valja 2 in tlačno komoro 11 sekundarnega tlačnega valja 3.The apparatus for filling a compressed propellant tank in a firearm according to the invention consists of at least one pressure means 1 comprising a pair of reciprocating pressure cylinders, namely a primary pressure cylinder 2 and a secondary pressure cylinder 3. In accordance with the invention, that both pressure cylinders 2, 3 comprise the same tubular piston 4 which passes at the point 4a of the connection of the two pressure cylinders 2, 3 from the first pressure cylinder to the other without sealing. Each free end of said tubular piston rod 4 is fitted with one piston, namely the primary piston 5 arranged in the primary pressure cylinder 2, and the seconds piston 6 arranged in the secondary pressure cylinder 3. In the described embodiment, the primary piston 5, and thus the primary piston a pressure cylinder larger than the secondary piston 6. Said tubular piston 4 on the side of the primary piston 5 penetrates it so that on the side facing away from the secondary piston 3, it protrudes from the plane of the primary piston 5. Said projections 7 of the tubular piston 4 , which is always located only inside the pressure cylinder 2, 3, is fitted with an axial extension 8 whose free end always protrudes from the primary pressure cylinder 2 and is fitted with a non-shown drive mechanism by means of which said piston 4 and the said piston 5 , 6 moves in the axial direction of said pressure means 1. Said projection 7 of the tubular piston 4 is designed with a transverse through hole 9, which allows fluid connection inside The tubular piston rod 4 has a pressure chamber 10 of the primary pressure cylinder 2 and a pressure chamber 11 of the secondary pressure cylinder 3.

Nadalje je cevasta batnica 4 na strani sekundarnega bata 6 zaprta s protipovratnim ventilom 12 na način, da preprečuje pretok medija, ki se ga stiska, iz tlačne komore 11 sekundarnega tlačnega valja 3 v tlačno komoro 10 primarnega tlačnega valja 2. Prostemu koncu sekundarnega tlačnega valja 3 je preko protipovratnega ventila 13 priključen izstopni vod 14, ki je povezan z neprikazanim rezervoarjem stisnjenega pogonskega sredstva pri strelnem orožju po izumu. Omenjenemu izstopnemu vodu 14 je izbiroma prigrajen še manometer 15 in/ali pretočni ventil 16. Pogonsko sredstvo, ki se ga stiska, vstopa v primarni tlačni valj po vstopnem vodu 17 z vgrajenim protipovratnim ventilom 18. Področje tlačnih valjev 2, 3, ki leži med vsakokratnim položajem omenjenih batov 5, 6 je medsebojno povezano preko mesta 4a prehoda omenjene batnice 4, s pomočjo prezračevalne luknje 19 v steni primarnega tlačnega valja 2 pa je omenjeno področje povezano z okolico z običajnim tlakom. Pri omenjenem tlačnem sredstvu 1 po izumu nastanejo tako tri različna tlačna področja, in sicer zgoraj omenjeni tlačni komori 10, 11 in med njima nahajajoče se področje 20 z okoliškim tlakom.Further, the tubular piston 4 on the side of the secondary piston 6 is closed by a non-return valve 12 in such a way as to prevent the flow of the compressible medium from the pressure chamber 11 of the secondary pressure cylinder 3 to the pressure chamber 10 of the primary pressure cylinder 2. At the free end of the secondary pressure cylinder 3, an exit line 14 is connected via a non-return valve 13, which is connected to a non-displayed tank of the compressed propellant in the firearm of the invention. Said outlet line 14 is optionally fitted with a pressure gauge 15 and / or a flow valve 16. The compressing actuator enters the primary pressure cylinder after the inlet line 17 with a non-return valve 18. The area of the pressure cylinders 2, 3 lying between the respective positions of said pistons 5, 6 are interconnected via the passage 4a of said piston 4, and by means of a ventilation hole 19 in the wall of the primary pressure cylinder 2, said area is connected to the surroundings by normal pressure. According to the aforementioned pressure medium 1 according to the invention, there are thus three different pressure regions, namely the aforementioned pressure chambers 10, 11 and the region 20 with the surrounding pressure between them.

Seveda pa je po izumu predvideno, da se za dosego višjega tlaka medija medsebojno vzporedno poveže dva ali več tlačnih sredstev 1, ki sta/so tedaj na po sebi znan način gnani kot omenjeno zgoraj. V takšnem primeru je izstopni vod 14 prvega tlačnega sredstva povezan z vstopnim vodom 17 sosednjega tlačnega sredstva. Na tak način se lahko na enostaven način dosega znatno višje tlake kot z enim samim tlačnim sredstvom.Of course, it is contemplated according to the invention that in order to achieve a higher pressure of the medium, two or more pressure means 1 which are / are then driven in a manner known per se, as mentioned above, are connected in parallel. In such a case, the outlet line 14 of the first pressure means is connected to the inlet line 17 of the adjacent pressure means. In this way, considerably higher pressures can be easily achieved than with a single pressure medium.

Priprava za polnjenje rezervoarja stisnjenega pogonskega sredstva pri strelnem orožju po izumu deluje kot sledi. Če predpostavimo, da je začetni položaj batov 5, 6 kot je prikazan na sl. 1, se ob premiku omenjenih batov 5, 6 in batnice 4 s pomočjo neprikazanega gonila v smeri puščice A medij, v danem primeru zrak, v tlačni komori 10 prične stiskati in skozi skoznjo luknjo 9 prehaja v cevasto batnico 4. Protipovratni ventil 18 v vodu 17 za dovod zraka v primarni tlačni valj 2 preprečuje izstop zraka, ki se ga stiska, iz primarnega tlačnega valja 2. Če je tako nastali tlak v komori 10 zadosti visok, se s tem odpre tudi omenjeni protipovratni ventil 12 v cevasti batnici 4 in stisnjeni zrak se po cevasti batnici 4 prelije v tlačno komoro 11. Kot že omenjeno je področje 20 med obema batoma 5, 6 preko prezračevalne luknje 19 povezano z okolico, tako da presežek zraka v področju 20 lahko izstopi v okolico.The device for filling the tank of the compressed propellant in the firearm of the invention operates as follows. Assuming that the starting position of the pistons 5, 6 as shown in FIG. 1, when the said pistons 5, 6 and piston 4 are moved by means of a non-shown gearbox in the direction of arrow A, the medium, optionally air, compresses in the pressure chamber 10 and passes through the through hole 9 into the tubular piston 4. The non-return valve 18 in the conduit 17 for supplying air to the primary pressure cylinder 2 prevents the compressed air from escaping from the primary pressure cylinder 2. If the resulting pressure in the chamber 10 is sufficiently high, the said non-return valve 12 in the tubular piston 4 is also opened and compressed. the air flows through the tubular piston 4 into the pressure chamber 11. As mentioned above, the area 20 between the two pistons 5, 6 is connected to the surroundings through the ventilation hole 19, so that excess air in the area 20 can escape into the surroundings.

Pri gibanju batnice 4 in batov 5, 6 v nasprotni smeri, to je v smeri puščice B, nastane v • · območju pod batom 5 podtlak, ki odpre protipovratni ventil 18, s čimer se omogoči dovod svežega zraka v tlačno komoro 10 primarnega tlačnega valja 2. V področju 20 med batoma 5, 6 nahajajoči se presežek zraka se skozi prezračevalno luknjo 19 pretoči v okolico. V batnici 4 razporejeni protipovratni ventil 12 preprečuje prehod stisnjenega zraka iz področja visokega tlaka v tlačni komori 11 nazaj v področje nizkega tlaka v tlačni komori 10, zaradi česar tlak zraka v tlačni komori 11 narašča, dokler ni dosežen zadosten tlak, ki odpre protipovratni ventil 13 in omogoči prehod stisnjenega zraka visokega tlaka v omenjeni rezervoar stisnjenega pogonskega sredstva.When the piston rod 4 and pistons 5, 6 move in the opposite direction, that is in the direction of arrow B, a vacuum is created in the area · under the piston 5 which opens the non-return valve 18 to allow fresh air to be supplied to the pressure chamber 10 of the primary pressure cylinder. 2. In the area 20 between the pistons 5, 6, the excess air flowing through the ventilation hole 19 into the surroundings. In the piston rod 4, a non-return valve 12 prevents the passage of compressed air from the high pressure area in the pressure chamber 11 back to the low pressure area in the pressure chamber 10, causing the pressure in the pressure chamber 11 to increase until sufficient pressure is reached to open the non-return valve 13 and allow the passage of high-pressure compressed air into said compressed propellant tank.
