Filter element for filter system having resonator structure and filter system having resonator structure

The invention relates to a filter element (10) for a filter system (100), comprising a hollow cylindrical filter bellows (12), having a substantially closed base (18) on an end face (16), at least one element-side resonator structure (20) being implemented on the base (18) for noise attenuation of a flowing fluid, the element-side resonator structure (20) has at least two grooves (22, 24) separated from one another by a separating wall (26) at the outer side of the bottom (18), at least one of the two element-side grooves (22, 24) being connected in fluid communication to the interior (30) of the filter element (10) through an opening (28), the element-side resonator structure (20) being arranged in the filter housing (110) of the filter system (100) when installed as intended. The element-side resonator structure (20) is tightly sealed with respect to the housing-side resonator structure (120) complementary thereto. 本发明涉及一种用于过滤系统(100)的过滤元件(10)，所述过滤元件包括中空筒柱型过滤波纹管(12)，所述过滤元件在端面(16)处具有基本上封闭的底部(18)，至少一个元件侧的共振器结构
