Nozzle for liquefied petroleum gas = container j in particular

sum filling and. refilling of lighters - ·.

The hiring "concerns itself with a nozzle ₅ intended for liquid pressure gas containers with a high capacity, which is suitable for filling containers in fireplaces or similar devices and which is attached to the distributor valve of the container or designed in one piece with it ₀

Gas lighters generally contain a container built into the lighter, which however only has a very limited capacity and therefore has to be refilled relatively often. For this refilling, separate rinsing containers are generally used, which usually only have the contents of one filling and are therefore thrown away after the filling process. These refill containers are adapted to the individual types of lighter and can generally only be used for a certain brand . show the Feueraeugboden,

The main task of the controller is to find a to develop suitable nozzles for LPG containers, which allow adaptation to different containers to be refilled «so that with one and the same supply · = container the most varied of one-liner containers, especially those of different types of lighter, refilled can be «- ^ the new nozzle should be a allow as often as you like? so that a storage container Can be used with a large capacity ο

This object is achieved according to the invention in that several sealing rings with preferably a conical mouth surface are provided so that the free usable nozzle length corresponding to the number of sealing rings used to adapt to the respective filling container is variable. ,, whereby the sealing ring closest to the nozzle end provides the seal with respect to the filling opening of the seat surrounding the container "

An advantageous embodiment of the furnace is ,, that the tapered end portion of the nozzle _s aufweist- an extended cylindrical Sits in the nozzle, the axial bore opens and the sur receiving the filling opening of the container is intended to be filled "

An advantageous' development of the control sees

furthermore, that on the outer "circumference of the nozzle there is a seller arranged perpendicular to the nozzle axis ₅ on which the innermost sealing ring" is supported in a sealing manner under pressure during the kill process.

IDs is still cheap _? if the sealing rings are made of elastic material, "for example silicone rubber," which is resistant to the low temperatures that occur when the grass passes through the nozzle.

To avoid a blockage of the axial nozzle bore and its enlarged seat by abrasion particles the nozzle expediently made of metal

These and other details of "hiring go from the following description a-white in the drawing ILLUSTRATED EXAMPLES OF EXAMPLE henror. Show it

Figd shows an axial section through the upper rope of one with the container equipped with the nozzle according to the innovation?

Pig _o 2 a section similar to JB ¹ Ig ₀ T through a second embodiment of the furnace,

Figo 3 is a partially sectioned side view of full = container and fire eyes? -

Fig.4 a sectional view similar to Figo5 »but with ab · = deviating trained F-euerzug.

The bottle A has a large capacity and contains a "Any usable for cigarette lighters fuel ,, for example under pressure _s stagnant liquid petroleum gas" The Piasehe has above a resilient Yertellerventil B _9, the wears according to the innovation nozzle C which - as in Fig _o 2 is shown - can be formed in one piece with the valve B »The nozzle C can be covered by a cap 10 _{or the like}

The nozzle G contains a metallic «, essentially cylindrical elongated block having a lower end portion 12 which in the wall 14 of the expedient tapered Yentils B is inserted braced. The nozzle C has over its entire length a through hole on the upper end part 18 in a widened Sits 20 ends »

The end part 18 is conical on the outside from =, which makes it easier to place elastic sealing rings D ₉ D 'on the nozzle G ", In the illustrated embodiment, the nozzle G only carries the two sealing rings D ₅ D'" The number of these sealing rings can however, they can be chosen as required, The sealing rings D ₉ B ³

have a conical surface 22 and are made of elastic Shem material, for example silicone rubber "manufactured

The nozzle C also has a seller F on which the lower sealing ring D "rests with its surface 24 = the two sealing rings D ₅ D 'are placed with their central bores on the nozzle C until the lower sealing ring D' on the rope operator F comes to rest? The nozzle C then only protrudes with the end part 18 over the two sealing rings.

Fig. 3 shows the filling or refilling of the container 6 of a lighter Π by means of the bottle A through the filling nozzle G α The container G _{contains a filling opening 26 9} protruding into the lower seat 28 of the lighter H which is normally closed by a screw or a similar lülement ο The outer end of the filling opening 26 x ^ e is a small distance h from the bottom surface 30 of the lighter H "

When filling bsw ₀ lashfüllen of the container G, the nozzle G in the Teransohaulichte position brought the nozzle G ₃ absorbs in the dex ° Advanced seat 20 the filling opening 26, while the conical surface 22 abuts the seal ring D to the seat 28 and this versehließt "The effective free length h ^s

i) the nozzle G has the smallest possible here

Worth _? since the filling opening 26 is in the immediate vicinity of the bottom 30 »

To fill a certain amount of gas from the bottle Ä into the container G au, one presses on the bottle A ₉ 'while looking at the arrow χ so that the valve B is opened and at the same time pressure is exerted on the sealing rings D ₈ D ⁵ - is practiced _v , which are compressed in this way swisehen the seller F and the seat 28,

Gas passes through the open valve B and the bore 16 into the filling opening 26 and into the container G, without gas losses occurring, since the Sits 28 through the Sealing ring D is sealed and the sealing ring D 'opposite the plate 3? acts as a seal "so that the Exit γόη gas duroh the filling opening 26 along the outer surface of the nozzle C and the bore of the sealing rings Terhammed is.

Compartment filling the container G, the bottle A is removed from the lighter H, the valve B interrupting the passage of gas. The sealing rings D ₅ D 'are expediently made of cold-resistant silicone rubber because during the passage of the gas from the bottle A to. Container G temperatures below 0 ° C can be reached »

Figo4 shows a case in which the container G- 'of a differently designed fire draft H' is filled with the bottle A. The filler opening 26 is disposed more deeply in the seat 28 ,, so that the outer end of the filling opening 26 opposite the bottom 30 dee Feuerseugs H ^ä has a distance d ,, h is substantially greater than the distance adopted in Figo 3 ".

For Pullen this lighter "-, the upper sealing · = ring D removed from the nozzle C" so that an effective Du = senhöhe d · is reached, the h substantially greater than the sutor given height 'is (YGI ₀ Figure _e 1 ■ } _β - The filling opening 26 of the container G ^{5 also} inserts here again into the expanded seat 20 of the nozzle C «while the sealing ring D ^s tightly seals the seat 28, the tab A is pressed downwards in the direction of the arrow χ, - so the valve B opens again _? which results in the filling of the container 6 '»

Can be carried according to the innovation C nozzle whose effective free length by removing bsw _o placement of sealing rings changed _s can therefore be one and the same bottle of any -Lighter fill ",.

The embodiment shown in Figo2 shows a one-piece design of nozzle 0 * and valve B ⁹ "

while as shown in FIG _s is placed separately i nozzle C to the valve B.

Since the nozzle G is made of metal, for example brass, _{9 there} are no clogging of the bore 16 and the enlarged seat 20 even with prolonged use, which would have to be feared _{when using material that is subject to greater wear s, for example plastic j »}
