    • The invention relates to a filtering apparatus comprising a pot-type filter housing (10), a filter element (28) that is accommodated therein, a holding mechanism (38) which is disposed in the filter housing (10) in order to removably fix the filter element along the longitudinal axis thereof, 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 which are embodied on the interior face of the filter housing (10) as well as on the filter element (28). The inventive 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 which is placed parallel to the longitudinal axis in a radial direction and seals under the effect of the pressure applied thereto by the holding mechanism (38). The invention further relates to a filter element that is to be used in such a filtering apparatus.
    • 本发明涉及一种过滤装置,包括盆式过滤器壳体(10),容纳在其中的过滤器元件(28),设置在过滤器壳体(10)中的保持机构(38),以便可移除地固定 所述过滤元件沿着其纵向轴线,以及密封装置(60),其密封过滤器壳体(10)的盖(20)和过滤元件(28)之间。 保持机构(38)设置有配合的保持元件,其被实施在过滤器壳体(10)的内表面上以及过滤元件(28)上。 本发明的过滤装置不需要现有技术中已知的O型密封件,并且作为外壳盖在过滤元件和过滤器头之间沿径向方向延伸,因为密封装置(60)包围至少一个密封边缘 62)或密封表面,其在径向方向上平行于纵向轴线放置并且在由保持机构(38)施加到其上的压力的作用下进行密封。 本发明还涉及在这种过滤装置中使用的过滤元件。
