(54) Gasventil til fyrtøj.(54) Gas Valve for Firewood.

Opfindelsen angår en gasventil til fyrtøj af den art, hvor gasstrømningsvejen er forsynet med en lukkeventil, som omfatter et ventilhus, et ventillegeme til samvirkning med et ventilsæde, et styreorgan og to fjedre.BACKGROUND OF THE INVENTION The present invention relates to a gas valve for firearms of the kind in which the gas flow path is provided with a shut-off valve comprising a valve housing, a valve body for cooperation with a valve seat, a control means and two springs.

Man kender sådanne ventiler, i hvilke et ventillegeme er påvirket til lukkestillingen af et styreorgan, som virker på ventillegemet gennem en lukkefjeder, idet en anden fjeder direkte sikrer oplukningen, når styreorganet ikke virker mere.Such valves are known in which a valve body is actuated for the closing position of a control means acting on the valve body through a closing spring, another spring directly securing the opening when the control means no longer operates.

Den væsentligste ulempe ved disse kendte indretninger er, at lukke-og åbnefjedrene virker modsat, idet påvirkningskraften for ventillegemet mod ventilsædet afhænger samtidig af karakteristikkerne for hver af de to fjedre, og heraf følger, at hver ændring af åbnefjederens karakteristik, f.eks. ved slid, medfører en ændring af påvirkningskraften for ventillegemet mod dets ventilsæde.The major disadvantage of these known devices is that the closing and opening springs act opposite, in that the actuating force of the valve body against the valve seat depends simultaneously on the characteristics of each of the two springs, and consequently each change in the characteristics of the open spring, e.g. upon wear causes a change in the force of action of the valve body toward its valve seat.

Den foreliggende opfindelse har til formål at afhjælpe disse ulemper ved at foreslå en lukkeventil, i hvilken påvirkningskraften for ventillegemet mod dets ventilsæde er uafhængigt af åbnefjederens karakteristik og kun afhænger af lukkefjederens karakteristik.The present invention aims to overcome these disadvantages by proposing a shut-off valve in which the actuating force of the valve body against its valve seat is independent of the open-spring characteristics and depends only on the closing-spring characteristics.

Gasventilen ifølge opfindelsen er ejendommelig ved, at den ene ende af hver af fjedrene virker på styreorganet, at den anden ende af den ene fjeder, åbnefjederen, virker på ventilhuset for at sikre åbningen af ventilen, og at den anden ende af den anden fjeder, lukkefjederen, virker på ventillegemet for i lukkestillingen at holde dette mod ventilsædet med en kraft, der kun afhænger af dens egen karakteristik.The gas valve according to the invention is characterized in that one end of each of the springs acts on the control means, that the other end of one spring, the open spring, acts on the valve housing to secure the opening of the valve and that the other end of the other spring, the closing spring, acts on the valve body to hold this in the closing position against the valve seat with a force which depends only on its own characteristic.

Da åbnefjederen således ikke påvirker selve ventillegemet, er denne uden betydning for lukkefjederens påvirkning af ventillegemet, således at det kun bliver lukkefjederens karakteristik, der bestemmer den kraft, hvormed ventillegemet bliver holdt mod sit sæde.Thus, since the open spring does not affect the valve body itself, this does not affect the influence of the closing spring on the valve body, so that only the characteristic of the closing spring determines the force by which the valve body is held against its seat.

I en foretrukken udførelsesform har styreorganet et medbringerorgan, der er indrettet til under styreorganets bevægelse til åben stilling at gribe en på ventillegemet anbragt del og derved føre ventillegemet bort fra ventilsædet.In a preferred embodiment, the control means has a carrier means adapted to engage an open position on the valve body during movement of the control means and thereby guide the valve body away from the valve seat.

Herved opnås, at styreorganet, der påvirkes af åbnefjederen, under sin bevægelse til åben stilling medtager ventillegemet, der derved forlader ventilsædet.Hereby it is obtained that the control means, which is actuated by the open spring, during its movement to the open position includes the valve body, thereby leaving the valve seat.

Opfindelsen forklares nærmere i det følgende ved to udførelseseksempler under henvisning til tegningen, hvor fig. 1 viser et første eksempel på gasventilen ifølge opfindelsen set i snit og med ventilen i lukkestillingen, fig. 2 det samme, men med ventilen i åben stilling, 3 144393 fig. 3 en anden udførelsesform, hvor ventilen er i lukkestillingen og fig. 4 det samme, men med ventilen i åben stilling.The invention will be explained in more detail in the following by two embodiments with reference to the drawing, in which fig. 1 shows a first example of the gas valve according to the invention in section and with the valve in the closing position; FIG. 2, but with the valve in the open position, FIG. 3 shows another embodiment in which the valve is in the closing position and FIG. 4 the same, but with the valve in the open position.

I fig. 1 og 2 består lukkeventilen af en hul del 1, et styreorgan 2 til lukning, et ventillegeme 3, en lukkefjeder 4 og en åbnefjeder 5.In FIG. 1 and 2, the closing valve consists of a hollow part 1, a closing member 2 for closing, a valve body 3, a closing spring 4 and an open spring 5.

Den hule del 1 omfatter et cylindrisk hulrum 6 og en i bunden udført fordybning 7 med et ventilsæde 8 gennembrudt af en kanal 9, der udmunder i en ikke vist gasbeholder på et fyrtøj.The hollow portion 1 comprises a cylindrical cavity 6 and a recess 7 formed at the bottom with a valve seat 8 pierced by a channel 9 which opens into a gas container not shown on a fireplace.

Ventillegemet 3 omfatter dels en tætningsdel 10, dels en stamme 11, hvis hoved 12 er større end stammen.The valve body 3 comprises partly a sealing member 10 and partly a stem 11 whose head 12 is larger than the stem.

Styreorganet 2 er cylindrisk og omfatter en cirkulær rille 13 til optagelse af en tætningsring 14 og en fordybning 15, i hvis bund der findes en kanal 16, som udmunder i en ikke vist brænder på fyrtøjet.The guide member 2 is cylindrical and comprises a circular groove 13 for receiving a sealing ring 14 and a recess 15, at the bottom of which is a channel 16 which opens into a burner on the fireplace not shown.

En hulskive 17, hvis midterhul tillader passage af stammen 11, men ikke passage af hovedet 12 på denne stamme, er anbragt mellem styre-organet 2 og fjedrene 4 og 5.A hollow disc 17, whose center hole permits passage of the stem 11 but not the passage of the head 12 of this stem, is arranged between the guide member 2 and the springs 4 and 5.

Disse fjedre støtter dels mod nævnte hulskive 17 dels mod bunden af hulrummet 6 for åbnefjederens vedkommende og mod ventillegemet 3 for lukkef j ederens vedkommende.These springs support partly against said hollow disc 17 and partly towards the bottom of the cavity 6 for the open spring and against the valve body 3 for the closing spring.

Funktionen af denne gasventil er som følger: i fig. 1, d.v.s. i lukkestillingen, påvirker en ikke vist del permanent styreorganet 2 efter pilen 18, hvilket styreorgan over hulskiven 17 sammentrykker fjedrene 4 og 5. Få grund af denne sammentrykning holder lukkefjederen 4 ventillegemet i lukkestillingen, d.v.s. med tætningsdelen 10 lukkende presset mod ventilsædet 8, og ventilen er således lukket, således at gas i kanalen 9 ikke kan undslippe.The function of this gas valve is as follows: in FIG. 1, i.e. in the closing position, a portion not shown permanently actuates the control member 2 after the arrow 18, which control means over the hollow disk 17 compresses the springs 4 and 5. Due to this compression, the closing spring 4 holds the valve body in the closing position, i.e.. with the sealing member 10 closing pressed against the valve seat 8 and the valve thus closed so that gas in the duct 9 cannot escape.

Når påvirkningen efter pilen 18 ophører, skubber lukkefjederen 4 og åbnefjederen 5 hulskiven 17 og dermed ligeledes styreorganet 2 opad, hvorved dette fjernes fra ventillegemet 3.When the actuation after arrow 18 ceases, the closing spring 4 and the open spring 5 push the hollow washer 17 and thus also the guide member 2 upwards, thereby removing it from the valve body 3.

4 1443934 144393

Bevægelsen af hulskiven 17 og styreorganet 2 fortsætter, indtil hulskiven går imod hovedet 12 på ventilstammen 11. Herved ophører virkningen af fjederen 4, fordi den er placeret mellem ventillegemet 3 og hulskiven 17. Åbnefjederen 5 fortsætter alene at trykke på hulskiven 17. Dette medfører, at styreorganet 2 og ventillegemet 3 hæves, hvorfor kanalen 9 kommer i forbindelse med kanalen 16.The movement of the hollow disk 17 and the control means 2 continues until the hollow disk goes against the head 12 of the valve stem 11. This stops the action of the spring 4, because it is located between the valve body 3 and the hollow disk 17. The open spring 5 only presses on the hollow disk 17. This results in the control member 2 and the valve body 3 are raised, which is why the channel 9 comes into contact with the channel 16.

Efter brugen trykker den ikke viste del på ny efter pilen 18 mod styreorganet 2, som bevæger sig nedad i hulrummet 6 og sammentrykker fjedrene 4 og 5- Då grund af denne sammentrykning holder lukkefjederen 4 ventillegemet i lukkestillingen, d.v.s. med tætningsdelen 10 trykket mod ventilsædet 8. Ventilen er således lukket, og gassen i kanalen 9 kan ikke undslippe.After use, the portion not shown after the arrow 18 again presses against the control member 2, which moves downwardly in the cavity 6 and compresses the springs 4 and 5- Then, because of this compression, the closing spring 4 holds the valve body in the closing position, i.e.. with the sealing member 10 pressed against the valve seat 8. The valve is thus closed and the gas in the duct 9 cannot escape.

I lukkestillingen har sammentrykningen af åbnefjederen 5 ingen indvirkning på den kraft, der holder ventillegemet 3 mod ventilsædet 8. Hår afstanden mellem hulskiven 17 og ventillegemet 3 en gang er bestemt, afhænger denne kraft kun af karakteristikken for lukkefjederen 4.In the closing position, the compression of the open spring 5 has no effect on the force holding the valve body 3 against the valve seat 8. Once the distance between the hollow washer 17 and the valve body 3 is determined, this force depends only on the characteristics of the closing spring 4.

Det er muligt at variere ventilen ifølge opfindelsen, f.eks. som vist i fig. 3 og 4, der viser en lukkeventil, som består af et hult legeme 21, et styreorgan 22, et ventillegeme 23, en lukkefjeder 24, der er en trykfjeder, og en åbnefjeder 25, der er en trækfjeder.It is possible to vary the valve according to the invention, e.g. as shown in FIG. 3 and 4, showing a closing valve consisting of a hollow body 21, a control member 22, a valve body 23, a closing spring 24, which is a compression spring, and an open spring 25, which is a tension spring.

Det hule legeme 21 har et cylindrisk hulrum 26, i hvis bund der er et ventilsæde 28, som er gennembrudt af en kanal 29, der udmunder i fyrtøjets ikke viste gasbeholder.The hollow body 21 has a cylindrical cavity 26, at the bottom of which is a valve seat 28, which is pierced by a duct 29 which opens into the gas tank of the fireplace not shown.

Væggen i hulrummet 26 er gennembrudt af en kanal 36, der udmunder i fyrtøjets ikke viste brænder.The wall of the cavity 26 is pierced by a channel 36 which opens into the burner of the fireplace not shown.

Ventillegemet 23 bærer dels en tætningsskive 30 dels en stamme 31, hvis hoved 32 er større end stammen.The valve body 23 carries partly a sealing disk 30 and partly a stem 31, the head 32 of which is larger than the stem.

Styreorganet 22 omfatter et hult kammer 35 og en stamme 33, der går igennem en tætningsskive 34.The control means 22 comprises a hollow chamber 35 and a stem 33 passing through a sealing disk 34.

5 1443935 144393

Lukkef jederen 24 går mod ventillegemet 23 og mod en hulskive 37, der er fastgjort til styreorganet. Hulskiven har et midterhul, der tillader passage af stammen 31, men ikke hovedet 32 på denne stamme 31.The closure spring 24 goes against the valve body 23 and toward a hollow disc 37 attached to the guide. The hollow disc has a center hole which permits passage of the stem 31 but not the head 32 of this stem 31.

Åbnefjederen 25 griber om en rille i skaftet 33 og om en skive 39, der er fastgjort over hulrummet 26 i nærheden af tætningsskiven 34.The open spring 25 engages a groove in the shaft 33 and a disc 39 attached over the cavity 26 in the vicinity of the sealing disc 34.

Funktionen af denne udførelsesform er som følger: i fig. 3, d.v.s. i lukkestillingen, virker et ikke vist påvirknings organ permanent efter pilen 38 mod styreorganet 22, der over hulskiven 37 sammentrykker lukkefjederen 24.The function of this embodiment is as follows: in FIG. 3, i.e. in the closing position, an actuating member (not shown) acts permanently after arrow 38 against the control means 22 which compresses the closing spring 24 over the hollow disk 37.

På grund af denne sammentrykning holder fjederen ventillegemet i lukkestilling, d.v.s. med tætningsskiven 30 trykket mod ventilsædet 28, således at ventilen er lukket,og gas i kanalen 29 kan ikke undslippe.Because of this compression, the spring holds the valve body in the closed position, i.e. with the sealing disc 30 pressed against the valve seat 28 so that the valve is closed and gas in the duct 29 cannot escape.

Hår påvirkningen efter pilen 38 ophører, skubber lukkefjederen 24 hulskiven 37 og styreorganet 22 opad. Samtidig trækker trækfjederen 25 styreorganet 22 opad, og hulskiven 37 trækker hovedet 32 på ventillegemet 23 op, hvorved kanalen 29 kommer i forbindelse med kanalen 36, som ender i br sender en.The hair after the arrow 38 ceases, the closing spring 24 pushes the washer 37 and the guide 22 upwards. At the same time, the tension spring 25 pulls the guide member 22 upwards, and the hollow disk 37 pulls up the head 32 of the valve body 23, whereby the channel 29 comes into contact with the channel 36, which ends in br sends one.

Efter brugen trykker påvirkningsorganet ved hjælp af passende midler atter permanent mod styreorganet 22 efter pilen 38. Herved bevæger styreorganet 22 sig nedad i hulrummet 26, åbnefjederen 25 trykkes sammen, og lukkefjederen 24 trykker ventillegemet 23 mod ventilsædet 28.After use, by means of suitable means, the actuating means again presses permanently against the control means 22 after the arrow 38. The control means 22 moves downwardly in the cavity 26, the open spring 25 is compressed and the closing spring 24 presses the valve body 23 against the valve seat 28.

Styreorganet 22 fortsætter med at holde tætningsskiven 30 mod ventilsædet 28, idet lukkefjederen 24 er sammentrykt, og ventilen befinder sig i lukkestillingen.The control means 22 continues to hold the sealing disk 30 against the valve seat 28, the closing spring 24 being compressed and the valve being in the closing position.
