    • The filter cartridge (5') according to the invention comprises a filtering element (1') made for instance of accordion-folded paper and defining, in the filter housing (7) in which it is inserted, an upstream chamber (17), where air yet to be filtered is contained, and a downstream chamber (18), where air already filtered is contained. The filtering element has an upstream face (13') arranged to face the upstream chamber (17), and a downstream face (15') arranged to face the downstream chamber (18). The upstream and downstream faces (13', 15') are substantially non-parallel and are mutually inclined. This allows producing filter housings and filter assemblies with reduced size without affecting their efficiency. The invention further relates to the filter housing for that cartridge and the filter assembly equipped with that cartridge.
    • 根据本发明的过滤器滤芯(5')包括一个过滤元件(1'),该过滤元件(1')例如由折叠折叠的纸制成,并且在其插入的过滤器壳体(7)中限定一个上游室(17) 其中容纳有待过滤的空气,以及包含已经过滤的空气的下游室(18)。 过滤元件具有面向上游室(17)的上游面(13')和布置成面向下游室(18)的下游面(15')。 上游侧和下游侧面(13',15')基本上不平行并相互倾斜。 这允许生产过滤器壳体和过滤器组件的尺寸减小而不影响它们的效率。 本发明还涉及用于该盒的过滤器壳体和装配有该盒的过滤器组件。
