    摘要: A connecting piece (1) between a carburetor (4) and an inlet channel (3) is disposed in an internal combustion engine (2) of a portable handheld motor-driven work apparatus such as a motor-driven chain saw, cutoff machine, et cetera. The connecting piece (1) serves to compensate for relative position changes between the engine (2) and the carburetor (4). The connecting piece (1) is made of elastic material and has an expansion fold (5) which functions to compensate for length changes. The length of the connecting piece can be changed from a pressed length (a) to an expanded length (b). The expansion fold (5) partitions the connecting piece (1) into a carburetor-end section (6) and into an engine-end section (7). The carburetor-end section (6) includes a circularly-shaped flow cross section and the engine-end section (7) includes a circularly-shaped flow cross section at the side facing toward the expansion fold (5) and has a flow cross section which departs from the circular shape at the end facing toward the engine. The connecting piece (1) includes on the inner side grooves (24) which run in the longitudinal direction.

    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).

    摘要: A connecting piece (1) is disposed between a carburetor (4) and an inlet channel (3) in an internal combustion engine of a portable handheld motor-driven work apparatus. The connecting piece functions to compensate for relative position changes between the engine and the carburetor (4), is made of elastic material and includes an expansion fold (5) for compensating for changes in position. The length of the expansion fold (5) is changeable from a collapsed to an expanded length. The expansion fold (5) subdivides the connecting piece (1) into a carburetor-end channel section (6) having a circularly-shaped cross section and an engine-end channel section (7) having a cross section departing from the circular form at the end facing toward the engine. The connecting piece (1) has a constant flow cross section over its entire length when the expansion fold (5) is collapsed.
