In particular, the second Füllelementgehäuseabschnitt 16.2 may be formed as a ring body with a cut in the side view V-shaped cross-section. The second Füllelementgehäuseabschnitt 16.2 can thus both at one of the mouth opening 8 facing the first system side 16.21, as well as one of the container mouth 3.2 assigning second system page 16.22 each be designed as a cone, or cone-like. Thus, the second Füllelementgehäuseabschnitt 16.2 may be formed as a centering unit, which centers the container mouth 3.1 of a container 3 and in the lowered position ABP with the second system side 16.22 in sealing position with the container mouth 3.2 passes. For this purpose, the second system side 16.22 may be formed of a rubber-like material for sealing the container mouth 3.2 lying in the sealing position, or a sealing device, for example a circumferential rubber seal, in particular a ring seal.

In this case, the first and / or the second sealing element 20, 21 may be formed as bellows and / or rolling diaphragm, so that between the first, inner and the second, outer sealing element 20, 21 of the annular gap 22 is formed, which may be an annular channel, for example , The expandable or displaceable housing wall section 16.3 can thus be a flexible, d. H. elastically deformable, act component. In particular, the expandable or displaceable housing wall section 16.3 can be connected to the first filling element housing section 16.1 as well as to the second filling element housing section 16.2 in a gas-tight and / or liquid-tight manner, for example adhesively bonded.

It may be provided that the lower housing element 19.2 is formed in one piece, in particular in one piece, and is thereby produced, for example, by means of an injection molding process. As already stated, there are other possibilities for fastening the first filling element housing section 16.1 of the lower housing element 19.2 to the upper housing element 19.1.

In this case, the filling element 2 preferably has a gas channel 23 in the region of its upper housing element 19.1, which opens fluid-tightly into the lower housing element 19.2 and which is provided with a gaseous medium for acting on the annular gap 22 formed in the lower housing element 19.2. In other words, therefore, the annular gap 22 can be acted upon via the gas channel 23 with the gaseous medium. In particular, the annular gap 22 can be acted upon via the gas channel 23 with a pressure which is increased in relation to the atmospheric pressure (overpressure) and / or a pressure (low pressure) which is lower than the atmospheric pressure. Particularly preferably, the gas channel 23 opens via the first stationary Füllgehäuseabschnitt 16.1 in the expandable or displaceable Füllelementabschnitt 16.2, which forms the along the Füllelementachse FA stretchable or displaceable annular gap 22. To supply the gas channel 23 with the gaseous medium, this (gas channel 23) can be fluid-tight with a flexible example. len control line 24 connected, in particular connected, be, wherein the control line 24 in turn is connected to a gas supply device, not shown. It goes without saying that a liquid may be used to effect the motions rather than a gas as shown above.

If the annular gap 22 is acted upon by an overpressure, the second Füllelementabschnitt 16.2 moves to its lowered position ABP (shown in Fig. 1), whereas upon application of the annular gap 22 with a negative pressure, the second Füllelementabschnitt 16.2 in its raised position ANP (shown in FIG Fig. 2) is moved. It is therefore initiated by an application of the annular gap 22 with a gaseous medium, a lifting or lowering movement in the second Füllelementabschnitt 16.2. In particular, the gaseous medium may be compressed air. Furthermore, for vertical guidance of the second Füllelementabschnittes 16.2 between the raised and the lowered position ABP, ANP along the Füllelementachse FA at least one guide means 25, for example a guide pin or pin 26 may be provided. The at least one guide pin or pin 26 can be arranged with its first free end face 26.1 on the underside of the upper housing element 19.1, in particular fixed, for example glued, soldered or welded, while the corresponding guide pin or pin 26 in the region of the first free end face 26.1 opposite second free end face 26.2 forms a guide portion 26.3, which leads the second Füllelementabschnitt 16.2 axially. For this purpose, the guide device 25 preferably has in the second filling element section 16.2 a recess 27, for example in the form of a blind hole or in the form of an annular groove, by means of which the corresponding guide section 26.3 of a corresponding guide pin or pin 26 between the raised and the lowered position ABP, ANP is guided vertically. The depth of the recess 27 is dimensioned such that the second free end face 26.2 is guided in the region of the guide section 26.3 between the raised and the lowered position ABP, ANP permanently in the recess 27, that is engaged with the recess 27. In particular, it is provided that the guide pin or pin 26 at its second free end face 26.2 a stop for the raised position ANP forms, so in the raised position ANP contact-fitted to recess 27.

In this case, a plurality of guide devices 25 designed in this way can be provided at preferably uniform angular intervals around the filling element axis FA. As can be seen in FIG. 3, six such guide devices 25 can be provided particularly advantageously.

FIGS. 4 and 5 show a further embodiment variant of a filling element arrangement 1 'according to the invention for filling containers 3 in the lowered position ABP (FIG. 4) or a raised position ANP (FIG. 3). This embodiment differs essentially from the embodiment of Figures 1 to 3 by an alternative embodiment of the liquid valve 6 ', which is known to the skilled person, however, in this alternative embodiment and therefore omitted a more detailed explanation of the same, and in an alternative embodiment of at least one guide device 25 '.

In this embodiment variant of FIGS. 4 and 5, too, at least the extensively or displaceably formed housing wall section 16.3 is formed from a first sealing element 20 and a second sealing element 21 provided for the first sealing element 20 while leaving a gas-tight annular gap 22, wherein the between the first and second sealing element 20, 21 formed gas-tight annular gap 22 to initiate the controlled movement of the second Füllelementabschnitt 16.2 is acted upon by a gaseous medium.

In this case, the first and / or the second sealing element 20, 21 may be formed as bellows and / or rolling diaphragm, so that between the first and the second sealing element 20, 21 of the annular gap 22 forms, which may be, for example, a ring channel. In particular, the annular gap 22 which can be acted upon by the gaseous medium forms between the first sealing element 20 and the at least one guide device 25 'for vertically guiding the second filling element section 16.2 between the raised and lowered positions ABP, ANP along the filling element axis FA. The at least one guide device 25 ' is designed to separate the pressure and / or liquid-tight free space between the first and second sealing element 20, 21 in a gaseous medium acted upon by the annular gap 22 and in a non-pressurized inner region 28 each other gas-tight.

For this purpose, the guide means 25 'have at least two mutually vertically displaceable, sleeve-shaped guide elements 29.1, 29.2, which surround the Füllelementachse FA preferably coaxially and fully and the free space between the first and second sealing element 20, 21 in the annular gap 22 and the unpressurized separate inner area 28 in a gastight manner. For vertical, mutually sealed displacement of the two sleeve-shaped guide elements 29.1, 29.2 to each other, a preferably fully circumferentially about the Füllelementachse FA circumferential sliding seal 29.3 be provided, which allows the mutual vertical, gas-tight displacement of the two guide elements 29.1, 29.2 relative to each other. In particular, the two guide elements 29.1, 29.2 may be formed as relatively vertically movable, nested guide sleeves, which support each other, for example via guide belts and the gasket seal off the annular gap 22 from the non-pressurized inner region 28 via the sliding seal 29.3. The first guide element 29.1 is arranged on the underside of the upper housing element 19.1, in particular fastened, for example, glued, soldered or verscheißt. For this purpose, the first guide element 29.1 form a flange portion, or have, via which the gas channel 23 opens into the annular gap 22. In the overlapping region of the two guide elements 29.1, 29.2 may be a working space 50 for at least one spring 51, in particular a compression spring may be provided, which is clamped in this working space 50, in particular under bias of the compression spring added. The working chamber 50 may be connected via an opening 52 with the unpressurized inner region 28 such that upon initiation of a lifting and / or lowering movement of the second Füllelementgehäuseab- section 16.2 pressure equalization between the working chamber 50 and the unpressurized area 28 takes place. In particular, the second Füllelementgehäuseabschnitt 16.2 be formed by the guide means 25 ', in particular of the second guide member 29.2. In this case, the Füllelementgehäuseabschnitt 16.2 on its second system side 16.22 a sealing device 18, for example, a sealing lip, have, so that the respective container 3 comes in the lowered position ABP with its container mouth 3.1 in sealing position. In an alternative embodiment, not shown, the second sealing element 21 is formed by the guide means 25 'and thus only the annular gap 22 essential to the invention between the first sealing element 20 and the guide means 25' is provided. Furthermore, in all embodiments of the filling elements 2 further, as known from the prior art, various gas channels 30 and flow paths are formed, which are controllable by closed for example in the non-activated state control valves 31 and 32 and so among other things a flow path via the return gas channel 33rd can be connected by activating or opening the control valve 31 with the example formed as a relief channel annular channel 5.2, and another flow path through which can be connected by activating or opening the control valve 32 of the return gas channel 33 with the example designed as a gas channel annular channel channel 5.1. Via the controlled flow paths 30 by means of the control valves 31 and 32, intensive CIP cleaning and / or sterilization of the filling elements 2 can also be achieved in the case of an annular space closed with a closure or with a flushing cap or CIP cap and with the liquid valve 6 open and the control valve 1 opened the filling machine possible. For the pressure filling shown in FIGS. 1 and 4, the height-adjustable second filling housing section 16.2 is moved into its lowered position ABP, which comes into sealing contact with the container mouth 3.1. Thus, in particular the return gas channel 33 for a flowing gas path 30 is released by the second Füllelementgehäuseabschnitt 16.2. When descending to its lowered position ABP designed as a cone second Füllelementgehäuseabschnitt 16.2 centered the container mouth 3.1 in particular by means of the second system side 16.22 before he comes with or on the container mouth 3.1 in sealing position. For this purpose, the annular gap 22 is acted upon by an overpressure. During pressure filling, at least one pre-tensioning of the container takes place before the actual filling phase. ters 3 with the inert gas under pressure, which flows in open control valve 32 from the annular channel designed as a clamping gas channel 5.2 and the gas channel 30 in the arranged in sealing position on the filling element 2 container 3. During the subsequent filling phase and in particular during the Schnellfüllphase with open liquid valve 6, the inert gas, which is increasingly displaced from the inflowing into the container 3 contents from the container interior, via the return gas channel 33 and adjoining gas channel 30 and the open control valve 31 the returned as a relaxation channel trained annular channel 5.1.

The invention has been described above in several embodiments. It is understood that numerous modifications and variations of the invention are possible without departing from the inventive concept. It goes without saying in the context of the present invention that, as already described above, instead of a gas, a liquid can also be used to effect the movements. Thus, in the context of the present invention, the term "gas-tight" is always to be understood as meaning "fluid-tight" and / or "liquid-tight." Analogously, a "gaseous medium" is always to be understood as meaning a "liquid medium".
