摘要： A handheld work apparatus has at least one tool which is driven by a combustion engine. A portion of an intake channel of the combustion engine is formed by an elastic connecting piece which has a first section and a second section between which an expansion fold is arranged. The expansion fold has a first side wall and a second side wall arranged downstream of the first side wall. A peripheral wall, which extends in the region of the largest outside diameter (a) of the expansion fold, is arranged in flow direction between the first side wall and the second side wall. The connecting piece has a stop for the expansion fold which prevents a segment of the first side wall adjoining the peripheral wall from bearing against the second side wall.

摘要： A filter element is provided for an air filter assembly of an internal combustion engine including a breather conduit and an intake conduit. The filter element includes a first wall, a second wall, filter media extending between the first and second walls, a first aperture in one of the first and second walls configured to receive air from the breather conduit, and a second aperture in one of the first and second walls configured to deliver air to the intake conduit. The filter media, the first wall, and the second wall define an interior chamber of the filter element. The first and second apertures connect to the interior chamber such that air filtered by the filter media mixes with unfiltered gases provided through the first aperture by the breather conduit prior to exiting the interior chamber through the second aperture into the intake conduit.
