| 摘要 |
The invention relates to a line duct for sealing a wall opening through which a line passes, comprising an elastomer body with a series of layers surrounding the line. The elastomer body and the series of layers are made up here of a number of respective one-piece elastomer body parts (2a, b, c, d) with shells (4a, b, c, d), according to the invention there being arranged between the shells (4a, b, c, d) of an elastomer body part (2a, b, c, d) at least two shells (4a, b, c, d) of other elastomer body parts (2a, b, c, d). |

1. A line duct for establishing sealing closure of an opening in a wall through which a line passes, comprising an elastomer body for sealing contact on said line made up of a plurality of one-piece elastomer body parts (2a, b, c, d),
it being possible to clamp said elastomer body with a tensioning device and in this way to press it onto said line such as to form a seal, said elastomer body parts (2a, b, c, d) being designed to produce, in an assembled state, a series of a number of neighbouring shells (4a, b, c, d) in respect of a direction (3) determining a distance from a centre axis of said line, in a pressed state of said elastomer body said line being completely surrounded by said shells (4a, b, c, d) in each layer of said series, a plurality of, in said distance direction (3), consecutive shells (4a, b, c, d) being provided on at least one of said elastomer body parts (2a, b, c, d) and there being a space (5a, b, c, d) between two of said shells (4a, b, c, d), next neighbouring in said distance direction (3), of said at least one elastomer body part (2a, b, c, d), in which a shell (4a, b, c, d) of an elastomer body part (2a, b, c, d) different from said at least one elastomer body part (2a, b, c, d) forming said space (5a, b, c, d) is arranged, characterised in that in said space (5a, b, c, d) there are arranged a plurality of, in said distance direction (3), next neighbouring shells (4a, b, c, d) of at least one other of said elastomer body parts (2a, b, c, d), and wherein those of said shells (4a, b, c, d) that are next neighbouring to one another in said distance direction (3) in said space (5a, b, c, d) respectively belong to others of said elastomer body parts (2a, b, c, d). |
