Abstract
A filtering apparatus includes a pot-type filter housing (10), a filter element (28) accommodated in the housing, a holding mechanism (38) disposed in the filter housing (10) to removably fix the filter element along its longitudinal axis, and a sealing device (60) that seals between a lid (20) of the filter housing (10) and the filter element (28). The holding mechanism (38) is provided with cooperating holding elements embodied on the interior face of the filter housing (10) as well as on the filter element (28). The filtering apparatus dispenses with the need for O-seals that are known in prior art and extend in a radial direction between the filter element and the filter head as a housing lid because the sealing device (60) encompasses at least one sealing edge (62) or sealing surface placed parallel to the longitudinal axis in a radial direction and seals under the effect of the pressure applied it by the holding mechanism (38). The invention further relates to a filter element that is to be used in such filtering apparatus.
