Abstract

The invention is directed to a carburetor arrangement in a housing (1) and especially in the housing of a work apparatus such as a motor-driven chain saw or like portable handheld work apparatus. An engine (2) is mounted in the housing (1) and has an inlet channel (3) which is connected via a connecting pipe (4) to the intake channel section (5) of a membrane carburetor (6). An intake air filter (10) is mounted on the carburetor (6) on the end face (17) facing away from the connecting pipe (4). Combustion air is supplied through the intake air filter (10). To avoid a damaging warming of the carburetor, a heat-draining component (20) is mounted on the end face (17) of the carburetor which faces away from the connecting pipe (4). The component (20) projects beyond the contour of the carburetor (6).
