Embodiment Construction
[0014] exist figure 1 The through-guide shown in the figure constituted as a filling through-guide for a plastic fuel container comprises a first nipple element 10 and a second nipple element 12 which can be mounted on a wall 16 ( figure 2 ) are connected to each other through the through opening 14, and here provide access to the interior of the container, which is fluid-tight to the outside. For this purpose, the first pipe connection element 10 has a first pipe body 18 with an external thread 20 in its end region, and the second pipe connection element 12 has in its end region assigned to the first pipe connection element Second tubular body 22 with complementary internal thread 24 . The first pipe connection element 10 also has a flange 26 surrounding the pipe body 18 at a distance from the external thread 20 , which flange has a side facing the wall 16 with a groove 28 arranged here, The sealing element 30 is formed as an O-ring. On the opposite side of the flange the...

The invention relates to a feed-through device for a wall (16), comprising a first and a second stub element (10, 12), which can be connected to each other through an opening (14) of the wall (16), wherein the first stub element (10) has a flange (26), which bears a sealing element (30), which lies against a wall part adjacent to the opening (14) in the wall (16) in a fluid-tight manner in the connected state of the two stub elements (10, 12), and wherein a supporting element (36) is arranged on the second stub element (12), which supporting element is supported on the other side of the wall (16) with respect to the sealing element (30) of the first stub element (10) in the state in which the two stub elements (10, 12) are connected to each other. According to the invention, in order to achieve reliable and durable sealing of the device with respect to an interior of a container, in particular a plastic fuel container, said interior being surrounded by the wall (16), according to the invention the supporting element (36) is connected by means of an elastic part to the second stub element (12), which elastic part permits a limited displacement of the supporting element (36) in relation to the second stub element (12) at least in the direction of a longitudinal center axis of the stub element (12).
Description
technical field [0001] The invention relates to a through-guiding device for a wall, comprising a first pipe joint element and a second pipe joint element, the first pipe joint element and the second pipe joint element can pass through through openings of the wall body to each other connection, wherein the first fitting element has a flange which carries a sealing element which, in the connected state of the two fitting elements, rests in fluid-tight contact with the through-opening in the wall. On the adjacent wall part, and, on the second pipe joint element, a support element is provided, which supports the sealing of the opposite first pipe joint element of the wall in the state where the two said pipe joint elements are connected to each other. components on the other side. Background technique [0002] In the case of containers with walls, it is often necessary to gain access to the interior of the container in order to, for example, introduce fluids, which may be liqu...
