Abstract

Ein handgeführtes Arbeitsgerät besitzt einen Verbrennungsmotor (15) sowie einen Luftfilter (38). Das zylindrische Filterelement (39) des Luftfilters (38) besitzt an einer Stirnseite einen Luftfilterboden (40), der mit einem am Luftfilterboden (40) angeordneten Zwischenflansch (43) einen Innenraum (85) begrenzt. In dem Innenraum (85) ist ein Abschnitt (41) eines Kanals geführt. Der Kanal ist durch mindestens eine quer zum Luftfilterboden (40) in den Innenraum (85) ragende Begrenzungswand (44) begrenzt, die am Zwischenflansch (43) und/oder am Luftfilterboden (40) angeformt ist und den Abstand (a) zwischen dem dem Luftfilterboden (40) gegenüberliegenden Boden (60) des Zwischenflanschs (43) und dem Luftfilterboden (40) überbrückt.

A hand-held implement has an internal combustion engine (15) and an air filter (38). The cylindrical filter element (39) of the air filter (38) has on one end face an air filter bottom (40) which defines an interior space (85) with an intermediate flange (43) arranged on the air filter bottom (40). In the interior (85), a portion (41) of a channel is guided. The channel is bounded by at least one transverse to the air filter bottom (40) in the interior (85) projecting boundary wall (44) which is integrally formed on the intermediate flange (43) and / or on the air filter bottom (40) and the distance (a) between the Air filter bottom (40) opposite bottom (60) of the intermediate flange (43) and the air filter bottom (40) bridged.
