摘要:
A filter element (1) has first and second end sections (3A, 3B) of a flat filter medium which are secured to one another. A sheathing (4) is provided, wherein said sheathing is compressed by the end sections (3A, 3B) and surrounds the end edges (9) of the end sections (3A, 3B). Alternatively, the filter element (1) has first and second end sections (3A, 3B) of a flat filter medium, wherein the first end section (3A) has a fold (5) having two fold legs (6A, 6B). The end section (3B) of the second end section (2B) is then compressed between the fold legs (6A, 6B).

摘要:
A filter apparatus and method for filtering a liquid. The filter apparatus comprises a housing that has at least one inlet for admission of the liquid to be filtered and at least one outlet for discharge of the filtered liquid. The apparatus further comprises at least two substantially cylindrical filter elements that can be fitted into the housing and which have a plurality of openings through which the liquid can flow to filter particles out of the liquid, and at least one filter cleaning element that can be introduced into a respective filter element in a region of an inner surface of the filter element to increase a flow speed of the liquid to be filtered so that substances in the filter element are flushed away. The filter elements are further connected in a parallel arrangement in the filter apparatus.
摘要:
A connecting element (1) for connecting at least two end portions (2A, 3A) of a flat filter medium (2, 3) has at least three legs (1A, 1B, 1C), one end portion (2A, 2B) each being introducible between two legs (1A, 1B, 1C). Under the influence of heat it is possible to connect the material of the legs with the material of the filter medium (2). The connecting element (1) can be used in a filter element (4) and in particular in a filtering device (5), for example an operating fluid filter for a motor vehicle. The object of a method for connecting at least two end portions (2A, 3A) of a flat filter medium (2, 3) is that the end portions (2A, 3A) are introduced between two legs (1A, 1B, 1C) each of a corresponding connecting element (1) and that through heating the material of the legs is connected with the material of the filter medium (1).
