Description

The invention relates to a connecting device for connecting a first channel element to a second channel element of a channel in accordance with claim 1 and a set of components of a connecting device in accordance with claim 17 in a substantially tight manner.

When using drainage channels, drainage pipes (line drainage) or drainage channels in tunnels or bridges, sealing between individual channel elements / channel elements / pipe elements or gutters / channels / pipes to other adjacent components is necessary. However, the structures (tunnels / bridges) into which the gutters, channels or pipes are installed are subject to considerable changes of shape / movement, e.g. due to temperature-dependent dimensional changes, settlement or necessary shifts of the structure or its parts.

This is especially true in tunnels, which often consist of a large number of interconnected individual (tunnel) components (blocks). The tunnel blocks can have a high dimensional change or settling phenomena with the very large dimensions of the tunnels (for example, miles long and several meters in diameter), which lead to displacements of the individual tunnel components relative to each other. Both in the longitudinal direction of the tunnel and in the transverse and vertical direction of the tunnel, displacements of the block joints, e.g. in the centimeter range, possible.

Drainage channels, drainage pipes or drainage channels which are installed in such structures must therefore adapt to these special requirements, in particular dimensional changes and displacements. The problem here is that drainage channels, drainage pipes or drainage channels, especially made of polymer concrete, by means of previously known connection devices are relatively rigidly interconnected or with adjacent components.

This leads, in particular in tunneling, to the fact that a drainage strand is leaking, damaged or impaired in functionality due to the movements (for example dimensional changes and / or displacements) of the tunnel segments (blocks), since no movements, especially in the centimeter range, are possible without loss of tightness. In addition, there is a risk that the channel body, tubular body or channel body due to the large stresses occurring cracks or breakage. A proper use of the gutter / pipe / channel or the gutter / pipe string / channel strand, namely the targeted and complete dissipation of, for example, liquids, bulk solids, dusts or gases is no longer possible in the occurrence of such damage and has a costly remedial measure Episode.

The invention is based on the object to show a connecting device for substantially dense connection of two (channel) elements, wherein the connecting means a tight connection between the two (channel) elements also during or after a relative movement of the two (channel) elements to each other guaranteed in a technically simple manner.

This object is achieved by a connecting device according to claim 1.

In particular, the object is achieved by a connecting device for connecting a first channel element with a second channel element of a channel substantially at least in a lower region of the two channel elements when installed, comprising a first connection element connectable to the first channel element and having a first groove second connection seal member connectable to the second channel member with a spring, the spring being partially disposed in the first groove and the spring in the first groove having clearance of a first predetermined value, the first connection seal member being substantially parallel to the second connection seal member a plane spanned by the first groove plane is designed to be movable and arranged by the predetermined value such that at a relative movement which is at most as large as the predetermined value, the first connection sealing element with respect to the two Ite connection sealing element is substantially parallel to the plane spanned by the first groove, the substantially tight connection between the two channel elements is ensured at least in the lower region of the two channel elements.

An essential point of the invention is that the connection sealing elements are arranged to move against each other and that by the existing play of the spring in the groove even at or after a movement occurred of the two connection sealing elements relative to each other a substantially tight connection between the two connection sealing elements or the two channel elements is further guaranteed. The advantage of this is that relative movements between the two connection sealing elements or two channel elements connected to the connection sealing elements are possible without the tight connection between the channel elements failed. As a result, the maintenance costs and the maintenance costs of a channel decrease considerably. In addition, the channel elements which can be connected or connected to the connection device must withstand lower forces, since the occurrence of forces on one or both channel elements allows the two channel elements to move relative to one another. As a result, the channel elements can be made of a less expensive material or with less material, which in turn leads to lower production costs of the channel.

The tight connection is solid material, in particular liquid-tight, preferably gas-tight.

A movement or mobility substantially parallel to the plane spanned by the first groove does not mean that no movements can take place or take place perpendicular to the plane spanned by the first groove; For example, the spring may move further into or out of the groove. Likewise, the spring may move such that the spring pushes more or less strongly into the seal. However, these movements perpendicular to the plane defined by the first groove are normally (clearly) less than the (possible) movements parallel to the plane spanned by the first groove.

With the connection sealing elements, a corner connection of two channel elements with the properties described above is possible. In this case, the ends of the respective channel elements can be bevelled at a certain angle. The angle of the bevel of the two ends is the same size, so that a plane spanned by the first groove extends substantially parallel to a plane spanned by the spring. Also conceivable is the arrangement of the connection sealing elements in bows, in particular pipe bends.

According to the invention, a guide element, in particular a pipe or a channel, preferably a drainage pipe or a drainage channel, is considered as channel or channel element. By means of this guide element (channel or channel element), the transport and collection of various media, namely liquids, especially water or sewage, and the transport and collection of, for example, bulk solids, and at circumferentially closed channel elements, especially pipes, also of dusts or gases.

The object is alternatively also achieved by a connection device for connecting a first channel element to a second channel element of a channel at least in a lower region of the two channel elements when installed, comprising a first connection element connectable to the first channel element having a first groove second connectable to the second channel member connecting sealing member having a second groove, and a spring, wherein the spring is partially disposed in the first groove and partially in the second groove and wherein the spring in the first groove a game with a first predetermined value and in the second groove has a clearance of a second predetermined value, wherein the first connection seal member relative to the second connection seal member is substantially parallel to a plane defined by the first groove by the sum of the first predetermined value and the second predetermined value of a rt is movably arranged and arranged such that at a relative movement, which is at most as large as the sum of the first predetermined value and the second predetermined value of the first connection sealing element with respect to the second connection sealing element substantially parallel to a spanned by the first groove Level, the substantially tight connection between the two channel elements is ensured at least in the lower region of the two channel elements.

An essential point of this alternative solution is that the connection sealing elements are arranged to move against each other and that by the existing play of the spring in the grooves even after a movement of the two connecting sealing elements relative to each other a substantially tight connection between the two connection sealing elements or the two Channel elements is further ensured. This is advantageous in that relative movements between the two connection sealing elements or two channel elements connected to the connection sealing elements are possible without the tight connection between the channel elements failing. As a result, the maintenance costs and the maintenance costs of a channel decrease considerably. In addition, the channel elements which can be connected or connected to the connection device must withstand lower forces, since the occurrence of forces on one or both channel elements allows the two channel elements to move relative to one another. As a result, the channel elements can be made of a less expensive material or with less material, which in turn leads to lower production costs of the channel. With the connection sealing elements, a corner connection of two channel elements with the properties described above is possible. In this case, the ends of the respective channel elements can be bevelled at a certain angle. The angle of the bevel of the two ends is the same size, so that one of The plane spanned by the first groove extends substantially parallel to a plane spanned by the spring. Also conceivable is the arrangement of the connection sealing elements in bows, in particular pipe bends.

The tight connection is solid material, in particular liquid-tight, preferably gas-tight.

In one embodiment, the connecting device further comprises a seal, in particular a seal made of an elastomer, wherein the seal in the first groove and / or in the second groove is arranged, wherein the spring in direct contact with the seal, in particular in direct contact with the center of Seal, is arranged. An advantage of this is that the tight connection between the channel elements can be made technically simple and secure. In addition, the relative movement between the two connection sealing elements is facilitated by the presence of the seal, since the friction occurring between the compound sealing elements are reduced by the seal. In addition, damage to the spring and / or the groove is substantially prevented by movements of the connection sealing elements relative to each other by means of the gasket disposed therebetween.

The first groove and / or the second groove and the spring may be configured and arranged such that after the relative movement of the first connection seal member relative to the second connection seal member substantially parallel to a plane defined by the first groove, the spring is still in direct contact is arranged to the seal in the first groove and / or the seal in the second groove. As a result, it is ensured in a technically simple manner that the tight connection is reliably ensured even after the relative movement of the two connection sealing elements with respect to one another. In addition, a further movement, which is exactly opposite to the occurred relative movement of the two connecting sealing elements to each other, facilitated, since the seal reduces the frictional resistance.

The first and / or the second predetermined value may be between about 0.1 cm and about half the height or about one half the width of the first or second channel member. One advantage of this is that, even with very long channels, as well as with large relative movements between the two connection sealing elements, a substantially dense, i. a solid-tight, in particular liquid-tight, preferably gas-tight, connection between the two connection sealing elements and thus between the two channel elements is ensured.

The first connection seal member may be formed and arranged parallel to the longitudinal direction of the channel by a third predetermined value movable relative to the second connection seal member, and the seal may be made elastic such that at a relative movement that is at most as large as the third predetermined value, the first connection sealing element with respect to the second connection sealing element parallel to the longitudinal direction of the channel, the substantially tight connection between the two channel elements is ensured at least in the lower region of the two channel elements. This makes it possible that even with movements between the two connection sealing elements parallel to the longitudinal direction of the channel a tight connection between the two connection sealing elements or the two channel elements is further ensured. This can be ensured in a simple manner, a substantially tight connection between the two channel elements, even with movements in all three dimensions, i. in the two parallel to the plane defined by the first groove plane aligned dimensions, as well as in the dimension which is parallel to the longitudinal direction of the channel or perpendicular to the plane defined by the first groove plane. As a result, the maintenance costs and the maintenance costs continue to decrease. In addition, lower forces act in the longitudinal direction of the channel on the channel elements, since the two compound sealing elements can move away from each other when larger forces occur, while the density, i. the solid-tight, in particular liquid-tight, preferably gas-tight, compound is further ensured. As a result, the channel elements can be made of a less expensive material or with less material, which in turn leads to lower production costs of the channel

In a further embodiment, the spring and / or the first groove and / or the second groove are each substantially rectangular, in particular rectangular, rounded and / or chamfered, wherein at least three sides of the spring play with the first predetermined value in the first Groove and / or a game with the second predetermined value in the second groove. This reduces the production cost of the connecting device, since this is technically particularly simple design.

In a further embodiment, the spring and / or the first groove and / or the second groove are each substantially, arcuate, in particular elliptical or semi-elliptical, preferably circular or semicircular, formed. As a result, a particularly secure and dense, ie solid-tight, in particular liquid-tight, preferably gas-tight, connection between the ensures both channel elements, as occurring forces are distributed evenly.

In a further embodiment, the first connection sealing element and the second connection sealing element each comprise a substantially planar contact region, wherein the contact regions are in direct contact with each other and wherein the contact region of the first connection sealing element, the first groove and / or the second contact region of the second connection sealing element, the spring substantially surrounds. This prevents soiling, e.g. Mineral particles, dirt, dust, etc. reach the groove or the spring, which can adversely affect the tight connection between the two channel elements or can even make the leak-tight connection leaky. In addition, by preventing the penetration of foreign matter, the frictional resistance between the two joint sealing members does not substantially change, so that they can easily move relative to each other. As a result, the channel elements must withstand lower forces or stresses and the wear of the connection sealing elements is reduced.

The first contact region and / or the second contact region may have a smooth surface, in particular a surface with a Teflon layer and / or with a friction reducer, preferably a lubricating film. As a result, the frictional resistance between the two connection sealing elements is reduced. Thus, even with the occurrence of low forces, a relative displacement between the first connection sealing element and the second connection sealing element takes place, so that lower forces act on the respective connection sealing element (and the channel elements which can be connected or connected thereto), so that these are made of a more favorable material or can be produced with less material. This leads to lower manufacturing costs of the channel.

The first connection sealing element and / or the second connection sealing element can be designed such that they can be firmly connected to the respective channel element. The fixed connection significantly reduces the installation effort on site. In addition, a secure connection between the respective connection sealing element and the respective channel element is thereby achieved.

The connecting device may further comprise a traction device, in particular a clamping device, which connects the first connection sealing element to the second connection sealing element in a force-locking manner in the longitudinal direction of the channel. As a result, a separation of the two connection sealing elements is prevented in the longitudinal direction, which in turn prevents the penetration of dirt, dust, mineral particles, etc. to the spring or the groove or the seal. In addition, a frictional connection between the first and second connection sealing element is produced technically simple.

In a further embodiment, the first connection sealing element and / or the second connection sealing element has oblong holes for receiving connecting bolts and / or connecting screws, wherein in particular the oblong holes of the first connecting sealing element are arranged at an angle of approximately 90 ° offset from the oblong holes of the second connecting sealing element. As a result, a secure connection between the two connection sealing elements is ensured even with movements in (when installed) vertical or in the transverse direction of the channel. Thus, the substantially dense, i. the solid-tight, in particular liquid-tight, preferably gas-tight, connection ensures particularly safe and technically simple after the occurrence of relative movements between the two connection sealing elements.

At least a portion of the oblong holes can be formed groove-like. As a result, a smooth flat surface, in particular the contact areas, guaranteed, even if screws or bolts are arranged in the elongated holes.

The connecting means may further comprise connecting bolts and / or connecting bolts, wherein ends of the connecting bolts and / or ends of the connecting bolts and / or ends of corresponding nuts of the connecting bolts have a hemispherical or spherical outer shape. As a result, a simple sliding in corresponding slots is made possible. As a result, the frictional resistance between the two connection sealing elements continues to drop, so that lower forces occur on the respective connection sealing elements or channel elements. As a result, they can be made of a less expensive material.

The two connection sealing elements may each comprise a seal for the substantially tight connection of the respective connection sealing element with the respective channel element. This will technically be simply a safe, substantially dense, i. solid-tight, in particular liquid-tight, preferably gas-tight, connection between the respective connection sealing element and the channel element which can be connected or connected thereto is ensured.

In the context of this invention, the spring, the first connection sealing element with a groove and the second connection sealing element with a spring are each claimed individually as part of a connecting device described above.

In the following description, the same reference numerals are used for the same and the same parts acting.

1 shows a front view of an embodiment of the first compound sealing element according to the invention 10 , 2 shows a front view of an embodiment of the second compound sealing element according to the invention 30 , 3 finally shows a schematic view of an embodiment of the connecting device according to the invention 1 , where in 3 both the elements of the first connection sealing element 10 as well as the elements of the second connection sealing element 30 are shown for clarity. 3 serves to explain, at which positions, the elements of the first compound sealing element 10 and the second connection sealing member 30 if the two connection sealing elements 10 . 30 for forming the connection device 1 are joined together so that the in 1 shown front in contact with the in 2 is shown on the front. 3 thus shows a kind of X-ray view of the connection device 1 ,

The first connection sealing element 10 has a substantially rectangular outer periphery. The first connection sealing element 10 has centrally a substantially rectangular flow opening 27 through, through the wastewater or liquid through the first connection sealing element 10 can occur. Immediately adjacent to the flow opening 27 is a bordering first inner contact area 25a arranged. The first inner contact area 25a has a smooth surface. The (outer) shape of the first inner contact area is rectangular. The first inner contact area 25a will turn from a seal 20 enclosed. The seal 20 also has a substantially rectangular (outer) shape. The seal 20 is in a first groove 15 , ie in a depression opposite to the rest in 1 shown surface, the first connection sealing element 10 arranged. The first groove 15 also has a substantially rectangular shape.

The groove 15 preferably extends from the outer edges 17 or the outer circumference of the seal 20 up to the inner edges 17a out. However, it is also conceivable that the first groove 15 essentially to the flow opening 27 extends so that between the first groove 15 and the Flow opening 27 There is essentially no distance or only a very small distance.

At the outer edge of the first connection sealing element 10 is a substantially planar first contact area 25 educated. The first contact area 25 also has a substantially rectangular shape. At the inner edge of the first connection sealing element 10 , ie immediately after the flow opening 27 , is a substantially planar inner first contact area 25a educated. The inner first contact area 25a also has a substantially rectangular shape.

In the flat first contact area 25 are long hole holes 28 , in 1 three oblong holes 28 , educated. The oblong holes 28 in 1 are (when installed) to the left or right of the flow opening 27 and centrally below the flow opening 27 arranged.

It is also conceivable that the first connection sealing element 10 a different outer shape than the flow opening 27 or the groove 15 or the seal 20 having.

The second connection sealing element 30 also has a rectangular outer shape. Central in the second connection sealing element 30 is a flow opening 43 arranged. Through this flow opening 43 For example, the waste water flowing through the channel (s) may pass through the connection sealing member 30 to step.

At the inner edge of the second connection sealing element 30 , ie immediately adjacent to the flow opening 43 arranged, there is a substantially planar inner second contact area 40a which of the spring 35 is substantially completely enclosed. The feather 35 stands opposite this flat second contact area 40 the second connection sealing element 30 out. The feather 35 consists essentially of a head start, which is opposite to the remaining in 2 shown surface of the second connection sealing element 30 protrudes. The feather 35 surrounds or circumscribes the flow opening 43 and possibly the inner second contact area 40a Completely. Thus, the spring in 1 also a rectangular shape.

It is also conceivable that the groove 15 or seal 20 and / or the spring 35 only partially the flow openings 27 . 43 surrounds. For example, sometimes only in one (in the installed state / in the figure shown in the lower area) lower region a solid-tight or a liquid-tight connection between the channel elements needed, so that only in this lower area a first groove 15 and a spring 35 and possibly a seal 20 is available. For example, it is conceivable that only right, left and bottom in 1 respectively. 2 a first groove 15 and a spring 35 , as well as possibly a seal 20 is present, ie that this is U-shaped, while the top in 1 respectively. 2 no such elements are present, since in this area no liquid-tight connection is needed.

A substantially solid-tight compound means that the compound is substantially impermeable to solids such as debris, etc. A substantially liquid-tight compound means that the compound is suitable for liquids, e.g. Water, oil, grease etc., is essentially impermeable. A substantially gas-tight compound means that the compound is suitable for gases or gas mixtures, e.g. Air, oxygen, nitrogen, helium, etc., is substantially impermeable.

At the outer edge of the second connection sealing element 30 , immediately adjacent to the spring 35 arranged is a substantially planar second contact area 40 , This encloses the spring 35 essentially complete. The feather 35 stands opposite this flat contact area 40 the second connection sealing element 30 out.

In this second contact area 40 are several oblong holes 45 , in 2 three oblong holes 45 arranged. Two of the oblong holes 45 are at the same height (when installed, left and right of the flow opening) 43 ) while getting another slot hole 45 when installed centrally below the flow opening 43 located.

The oblong holes 45 the second connection sealing element 30 are horizontally formed in the installed state, while the slot bores 28 the first connection sealing element 10 in 1 (in the installed state) are designed to extend vertically. It is also conceivable, however, the reverse orientation of the respective elongated holes 28 respectively. 45 , It is also conceivable that some of the oblong holes 28 . 45 a Verbindungsdichtelements extend horizontally, while further slot bores 28 . 45 the same compound sealing element run vertically.

In one in the 1 - 4 not shown embodiment, wherein the second connection sealing element 30 without the inner second contact area 40a is formed, ie the spring 37 immediately adjacent to the flow opening 43 has the second connection sealing element 30 a larger flow opening 43 as the first connection sealing element 10 , If the connection device 1 is arranged so that the wastewater or the liquid first through the flow opening 43 the second connection sealing element 30 and then through the flow opening 27 of the first connection sealing element 10 occurs remains even after a relative displacement of the first connection sealing element 10 with respect to the second connection sealing element 30 the effective cross-sectional area or effective size of the common flow opening for the wastewater compared to before the relative displacement equal. No part of the second connection sealing element 30 thus arrives after a shift in the way of the flowing wastewater and the resistance when flowing through the waste water is not increased in this way.

In 3 are all elements of the front, ie the front, of the first connection sealing element 10 and the second connection sealing member 30 in the assembled state of the connecting device 1 visible, noticeable. This view serves to explain the positions of the elements of the two connection sealing elements 10 . 30 in the assembled state of the connecting device 1 , In the middle is the flow opening 43 the second transition sealing element 30 , Further out in 3 is inner second contact area 25a to see. Farther out, the first groove closes 15 at. Following this is still further out in 3 the feather 35 the second transition sealing element 30 to see. The feather 35 is located substantially centrally with respect to the seal 20 or first groove 15 , The feather 35 points opposite to the first groove 15 a game perpendicular to the longitudinal direction of the channel or parallel to a plane defined by the first groove plane. That means that the spring 35 in the in 3 shown basic position a first predetermined distance to the outer edge of the first groove 15 or seal 20 having.

This means that the spring 35 and thus with the spring 35 firmly connected connection sealing element 30 , in all four directions perpendicular to the longitudinal direction of the channel / parallel to the plane defined by the first groove, ie in 3 has a game up, down, right and left. In 3 is the game, ie the distance between spring 35 and outer edge of the first groove 15 or seal 20 , in all genanten four directions the same size. However, it is also conceivable that the game in the different directions (in 3 above, below, right and left) each have different values.

The longitudinal direction of the channel is perpendicular to that through the groove 15 spanned level. This plane runs parallel to the paper plane in 1 and 2 ,

The game of the spring 35 in relation to the groove 15 is set to a predetermined value by the width of the gasket 20 as well as the width of the first groove 15 in the first transition sealing element 10 as well as the size or dimensions of the spring 35 be determined.

The feather 35 and thus the second connection sealing element 30 can thus move as far as perpendicular to the longitudinal direction of the channel until the spring 35 in direct contact with the outer inner edges 17 the first groove 15 arrives.

In 3 is clearly seen that the oblong holes 28 the first transition sealing element 10 himself with the oblong holes 45 the second transition sealing element 30 essentially cross in the middle. As a result, even with a screw connection or a connection with bolts between the two connection sealing elements 10 . 30 by means of oblong holes 28 . 45 Ensures that the first connection sealing element 10 relative to the second connection sealing element 30 as well in 3 ) can move up or down, as well as to the right or to the left.

Through the existing game between spring 35 and the first groove 15 or the inner edges 17 the first groove 15 , ie, the predetermined distance between them, is also at a relative movement of the first sealing element 10 with respect to the second sealing element 30 a substantially liquid-tight connection between these two connection sealing elements 10 . 30 ensured. Even after a shift, the maximum play, ie the distance between spring 35 and first groove 15 corresponds, is the spring 35 still in direct contact with the seal 20 , Thus, even after such a maximum displacement, the liquid-tight connection between the two connection sealing elements 10 . 30 ensured, as the spring 35 still partially in the first groove 15 is arranged. Even without a seal 20 is the liquid-tight connection after a relative displacement of the two connection sealing elements 10 . 30 guaranteed to each other.

The two connection sealing elements 10 . 30 are each formed such that they each with a channel element 50 . 60 are substantially liquid-tight connectable. This connection is rigid, for example, so that a movement of the two channel elements 50 . 60 to each other to a relative movement of the first connection sealing element 10 to the second connection sealing element 30 leads. However, it is also conceivable that the connection sealing elements 10 . 30 with the respective channel element 50 . 60 have no rigid but a flexible connection.

An articulated connection, ie by means of joints, between the two connection sealing elements ( 30 . 60 ) is also conceivable.

4 shows a cross-sectional view of the connecting device 3 along the line IV-IV. In 4 is clearly recognizable as the spring 35 in the elastic seal 20 presses. The seal 20 is in the first groove 15 the first connection sealing element 10 arranged. The two flat contact areas 25 . 40 and the two flat contact areas 25a . 40a are arranged in direct contact with each other.

5 shows a schematic front view of another embodiment of the second compound sealing element according to the invention 30 , 6 shows a corresponding thereto further embodiment of the first compound sealing element according to the invention 10 , In 5 and 6 is in each case only the lower part of the second connection sealing element 30 or the first connection sealing element 10 shown.

In contrast to the connection sealing elements of 1 to 4 is in 5 respectively. 6 are the flow openings 27 . 43 open at the top. This means that in this way an upwardly open channel can be formed or a plurality of channel elements by means of the connection sealing elements 10 . 30 can be connected liquid-tight. The feather 35 the second connection sealing element 30 is (at least in the lower part in 5 ) formed substantially arcuate. The feather 35 has substantially the same arc shape as the (in the installed state) lower edge of the flow opening 43 , The groove 15 the first connection sealing element 10 has an arc shape corresponding thereto. The same applies to the seal 20 or their outer forms.

When assembled, the spring is located 35 or the outer edge 37 the feather 35 in direct contact with the seal 20 , Again, the spring has 35 a game with a predetermined value relative to the first groove 15 ,

The oblong holes 45 in the second connection sealing element 30 are formed vertically extending. These are in turn (when installed) on the left or right or bottom edge of the second contact surface 40 , The oblong holes 28 in the first connection sealing element 10 are formed horizontally extending. These are accordingly also (in the installed state) at the left or right or bottom edge of the first planar contact area 25 ,

It is also conceivable that the spring 35 not fixed to the second transition sealing element 30 is connected, ie no part of the second transition sealing element, but a separate element.

In a further embodiment, the connection sealing element 1 not from a first connection sealing element 10 and a second connection sealing element 30 is composed, but the connecting device 1 comprises two first connection sealing elements 10 between which a spring 35 is arranged as an independent component.

This spring would be at the in 2 illustrated connection sealing element 1 like a kind of frame around the flow opening 27 be educated.

The designed as an independent component spring 35 in this embodiment has a clearance with a first preset value from the first groove 15 of a first connection sealing element 10 and a clearance having a second preset value opposite to the second groove of the second "first connection seal member" 10 , Thus, the two connection sealing elements can 10 move each other and perpendicular to the longitudinal direction of the channel by a value equal to the sum of the play between the spring 35 and the first groove 15 and the spring 35 and the second groove corresponds. Thus, even greater relative movements between the two compound sealing elements 10 possible, while at the same time a substantially liquid-tight connection between the two connection sealing elements 10 and between the two channel elements 50 . 60 is guaranteed.

The independent spring is characterized by the pressure that exists between the two connection sealing elements 10 exists, held in their position. The spring also preferably presses centrally into the seal of the respective first connection sealing element 10 or is in direct contact with it.

The same is conceivable for the in 6 illustrated embodiment. Here are two first connection sealing elements 10 , as in 6 shown connected to a separate spring, which would also have a substantially arcuate shape.
