Embodiment Construction

[0017] A pot-shaped, bottom-closed, generally cylindrical filter housing 1 can be closed at its upper end by a cover part 3 which can be detachably connected to the housing 1 via a thread 5 . A filter element 9 can be accommodated in the housing 1 and has a hollow cylindrical filter medium 11 in a conventional design, for example in the form of a filter mat or a multilayer, folded or pleated filter body, The filter medium surrounds a tubular support body 13 coaxial with respect to the longitudinal axis 2 , which is injection molded from a plastic material. Such as image 3 As can be seen most clearly in , the support has a sequential sequence of circumferential rings 15 arranged at a distance from each other, of which only a few are marked in the figure and these The circular ring is connected in the usual manner with such supports 13 to an inner support, which is designed in cross-section as a triangular star with three branches 17 . On the end corresponding to the pot bott...

Abstract

A filter device having a filter element (9) forming a body extending along a longitudinal axis received in a housing (1) closed by a cover part (3). A sealing arrangement (49) is provided to form a fluid-tight seal between the housing (1) and the cover part (3). The sealing arrangement (49) is a component of a filter element (9) and is fixed to a sealing carrier (48) rigidly connected to the filter element.

Description

technical field [0001] The invention relates to a filter device having a filter element which forms a body extending along a longitudinal axis and which can be accommodated in a housing which can be closed by a cover part, wherein a A fluid-tight seal is formed between the housing and the cover part. The invention also relates to a filter element intended for said filter device. Background technique [0002] Filter devices for receiving filter elements are freely available on the market in various configurations, see eg EP 1287871A1 or EP 0891214B1. During the operation of such filter devices, the filter elements must be replaced at defined intervals, which must be carried out at shorter intervals when large volume flows to be filtered occur and / or heavily contaminated fluids are involved. Therefore, in such a filter device, it is desirable to realize such a design, in which the installation process for changing the filter element is designed relatively simple and convenie...
