Air intake device for IC engines of chain saws etc. has elements to remove dust separated from combustion air via carrier air flow

摘要

The intake device has elements (12) on the side of the contaminated air chamber (14) of the air filter (5), to remove the dust (11) separated from the combustion air (2) via a carrier air flow (10). The chamber is connected via an exhaust pipe (13) to the carrier air flow, which is separate from the combustion air. The carrier air flow is passed into a flow channel (15). A blower is the coolant air blower of the IC engine.
