Abstract:
An air filter for a fresh air system of an internal combustion engine may include a filter housing including a housing lid and a filter element arranged exchangeably in the filter housing separating a raw side from a pure side. The filter element may include an annular filter body, a first end plate, and a second end plate. A dust collector space may be disposed in the filter housing on the raw side and may be delimited axially by the housing lid and the first end plate. The housing lid may have a step which may radially delimit the dust collector space. A connection may be disposed in a circumferential section of the dust collector space which is not bordered by the step. The step may have a radial aperture fluidically connecting the dust collector space to a discharge stub, the radial aperture arranged diametrically opposite the connection.

Claim (Index 1):
An air filter for a fresh air system of an internal combustion engine, comprising:\n a filter housing including a housing pot, a housing lid, a raw air inlet, and a pure air outlet; a filter element arranged exchangeably in the filter housing and, therein, separating a raw side which is connected fluidically to the raw air inlet from a pure side which is connected fluidically to the pure air outlet; the filter element including an annular filter body composed of a filter material, a first end plate disposed on a first axial end side of the filter body, and a second end plate disposed on a second axial end side of the filter body; a dust collector space disposed in the filter housing on the raw side; the dust collector space delimited axially on one side directly by the housing lid; the dust collector space delimited axially on an other side directly by the first end plate; the housing lid having, on an inner side, a step which radially delimits the dust collector space and borders the dust collector space in a C-shaped manner in a circumferential direction; a connection disposed in a circumferential section of the dust collector space which is not bordered by the step, the connection open radially toward the dust collector space and axially toward an annular space of the raw side which encloses the filter body in the circumferential direction; a discharge stub arranged on the filter housing fluidically connecting the dust collector space to a surrounding area of the air filter; wherein the step has a radial aperture fluidically connecting the dust collector space to the discharge stub, the radial aperture arranged diametrically opposite the connection.
