Filter Element of a Filter for Filtering Fluids, and Filter

摘要

A filter element has a zigzag-folded filter medium. Filter medium sections joined by a fold edge define an intermediate fold space, respectively, with a fold base and fold peaks opposite the fold base. An elongate support section is arranged in the intermediate fold space on a filter medium surface of one of the filter medium sections. The support section extends perpendicular to the fold edges between fold base and fold peak. The support section has a height extension perpendicular to the filter medium surface that increases in longitudinal direction of the support section from fold base to fold peak. The support section has a free side facing away from the filter medium surface. The support section has a width extension parallel to the fold edges. The width extension decreases parallel to the filter medium surface and perpendicular to the longitudinal direction from fold peak to fold base.

1. A filter element of a filter for filtering fluids, the filter element comprising:
a zigzag-folded filter medium provided with a raw fluid side and a clean fluid side, wherein the filter medium comprises fold edges and filter medium sections extending between the fold edges, respectively, wherein two of the filter medium sections joined by one of the fold edges define an intermediate fold space, respectively, wherein the intermediate fold space defines a fold base and fold peaks at ends of the two filter medium sections opposite the fold base; an elongate support section arranged in the intermediate fold space on a filter medium surface of one of the filter medium sections of the intermediate fold space at the raw fluid side or the clean fluid side; wherein the elongate support section extends at a slant or perpendicular to the fold edges between the fold base and the fold peak of said one filter medium section; wherein the elongate support section has a height extension perpendicular to the filter medium surface; wherein the height extension increases in a longitudinal direction of the elongate support section in a direction from the fold base to the fold peak of said one filter medium section; wherein the elongate support section has a free side facing away from the filter medium surface; wherein the elongate support section has a width extension extending in a direction parallel to the fold edges, wherein the width extension decreases parallel to the filter medium surface and perpendicular to the longitudinal direction in the direction from the fold peak of said one filter medium section to the fold base.
