Abstract
A filter device is provided with a filter housing provided with a housing wall and with a filter element arranged in the filter housing. The filter element has an annular filter medium body and an end disk arranged at an end face of the filter medium body. The filter medium body surrounds in a ring shape an inwardly positioned flow space for receiving a fluid to be filtered. An annular circumferentially extending flow path is positioned between an outer contour of the end disk and an inner side of the housing wall of the filter housing. Guide vanes project into the annular circumferentially extending flow path. The guide vanes are fastened at the end disk at the filter element. A cover is arranged at the end disk at the filter element and covers a portion of the annular circumferentially extending flow path.
