Abstract
A connecting piece () between a carburetor () and an inlet channel () is disposed in an internal combustion engine () of a portable handheld motor-driven work apparatus such as a motor-driven chain saw, cutoff machine, et cetera. The connecting piece () serves to compensate for relative position changes between the engine () and the carburetor (). The connecting piece () is made of elastic material and has an expansion fold () 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 () partitions the connecting piece () into a carburetor-end section () and into an engine-end section (). The carburetor-end section () includes a circularly-shaped flow cross section and the engine-end section () includes a circularly-shaped flow cross section at the side facing toward the expansion fold () and has a flow cross section which departs from the circular shape at the end facing toward the engine. The connecting piece () includes on the inner side grooves () which run in the longitudinal direction.
