Abstract

The invention relates to a filter element consisting of a filter medium (10) which is folded in a zig-zag manner and designed in a concentric shape. End plates (11, 12) are arranged on the end sides of the medium. End plate (12) has a concentric opening as well as a first annular ring (14) and a second annular ring (15), and a sealing groove (16) arranged between the rings. A reinforcement plate (17) is arranged in the area between the filter medium and the rings (14, 15). The end surfaces (18, 19) of the rings (14, 15) are supported by the grooves (20, 21) of a filter element housing, the grooves running radially.
