Filter element and air filter

摘要

A filter element has a filter bellows and at least one support element arranged on the filter bellows that supports the filter element relative to a filter housing in which the filter element is to be arranged. The at least one support element is arranged on at least one edge of the filter bellows and projects outwardly past the filter bellows. The at least one support element is detachably or non-detachably attached on the filter bellows directly or indirectly. The at least one support element is preferably arranged on a corner of the filter bellows and projects past all sides of the filter bellows adjoining the corner. An air filter with a filter housing is furnished with the filter element.

1. A filter element comprising:
a filter bellows having
an inflow face receiving fluid to be filtered, the inflow face arranged a first axial side of the filter bellows;an axially opposing outflow face arranged an at axially opposite side of the filter bellows;wherein the inflow face and the outflow face are arranged such that a filter element axis extends through the inflow face and the outflow face on opposing sides of the filter bellows, the filter element axis defining a Z axis of a filter element coordinate system;the filter bellows having a front side and a laterally opposing rear side arranged on opposing sides of the filter bellows relative to a Y axis of the filter element coordinate system, the front side and the laterally opposing rear side extending from the inflow face to the outflow face;the filter bellows having a first end face and a laterally opposing second end face arranged on opposing sides of the filter bellows relative to an X axis of the filter element coordinate system, the first end face and the laterally opposing second end face extending from the inflow face to the outflow face and extending from the front side to the laterally opposing rear side; wherein a first flow face is either the inflow face or the outflow face, the first flow face having
a first flow face edge defined where the first flow face meets the front side of the filter bellows;a second flow face edge defined where the first flow face meets the laterally opposing rear side;a third flow face edge defined where the first flow face meets the first end face;a fourth flow face edge defined where the first flow face meets the second end face;a plurality of support elements configured as feet arranged on the filter bellows and adapted to support the filter element relative to a filter housing in which the filter element is to be arranged, the plurality of support elements having:a first end arranged at the first flow face and on at least one of the flow face edges of the filter bellows;an opposing second end, the second end forming a foot, the second end positioned outwardly away from the first end in a direction defined by the Z-axis, the foot configured to contact against the filter housing in which the filter element is to be arranged;wherein the plurality of support elements project in the Z axis direction, outwardly away from the first flow face and away from the filter bellows.
