Abstract
A sealing passage arrangement for a pipeline through a wall aperture in a housing of an internal combustion-engine is disclosed. The sealing passage arrangement is attached so as to be sealed by its housing edge delimiting the open side of the housing on a receiving surface and is constructed so that the disassembly of the housing can be done without previously stripping down the pipeline. A pipe connection is provided inside the housing before the housing is assembled, and an arrangement of the seal element in the wall aperture which can be effected simply, are provided. It is proposed for this purpose to construct the housing aperture extending from the housing edge into the housing wall, to provide in the latter a two-part seal element, to arrange one part of the latter upright on the receiving surface and to bring it into engagement with the other part retained in the edge aperture and to extend the pipeline between the two seal element parts.
