ABSTRACT:
The invention relates to an intake arrangement (1) for the combustion air (2) of an internal combustion engine (3) in a handheld work apparatus (4) such as a cutoff machine, a motor-driven chain saw or the like. An air filter (5) is provided for the cleaning of the combustion air (2) drawn in via an opening (6) of a filter housing (7). To discharge dust (11) accumulated in the air filter (5) a carrier airflow (10) is provided in a flow channel (16) and the filter housing (7) is fluidly connected with the aid of a discharge tube (13) to the flow channel (16). For a dosed metering of dust (11) from the filter housing (7), a shutoff member (14) is provided and the shutoff member (14) clears or closes the fluid connection between the flow channel (16) and the filter housing (7).
