Connecting piece |
摘要 |
An elastic connecting piece (1) is mounted between a carburetor (4) and an inlet channel (3) of an internal combustion engine (2). The engine (2) is especially an engine of a portable handheld motor-driven work apparatus such as a motor-driven chain saw, cutoff machine or the like. The connecting piece (1) includes a peripherally extending expansion fold (5) arranged between its ends in order to compensate for changes in length. The expansion fold (5) subdivides the connecting piece (1) into a carburetor-end section (6) and into an engine-end section (7). The annular gap (28) of the expansion fold (5) can be bridged by a seal lip (8). The connecting piece (1) includes a peripherally extending seal seat (9) of axial length (g) in the region of the expansion fold (5). The seal lip (8) can be placed in seal-tight contact with the seal seat (9) and substantially closes the expansion fold (5) fluid tight to the interior space of the connecting piece (1).
