Filter element e.g. oil filter element used in automotive sector, has support element with inner space whose cross sectional area is partially reduced by edge region towards central region

摘要

The filter element (1) has filter medium (3) and partially fluid-permeable support element (2) for receiving and non-holding of the filter medium in a support element inner space (20) extending along a longitudinal axis (11) between first and second edge supporting elements (5). The cross sectional area of ??the support element inner space is partially reduced by edge region towards a central region.
