Abstract

A filter element comprises one first and at least one second filter media body disposed at a common carrier body. At least one filter media body is formed in a curved manner.

First claim

What is claimed is:

1 . A filter element, comprising:
a first filter media body; and at least one second, separately formed filter media body; wherein the filter media bodies are through-flowable by a to-be-cleaned fluid; wherein the filter media bodies are arranged on a common carrier body; wherein the filter media bodies limit an intermediate flow chamber for the fluid; wherein at least one of the filter bodies is formed at least in sections in a curved manner; wherein the filter element has a longitudinal axis.

2 . The filter element according to claim 1 , wherein
all of the filter media bodies are formed at least in sections in a curved manner.

3 . The filter element according to claim 1 , wherein
at least one filter media body of the filter media bodies comprises one curved and one straight section.

4 . The filter element according to one of claim 1 , wherein
at least one of the filter bodies is formed exclusively in a curved manner.

5 . The filter element according to claim 1 , wherein
a curvature of the if the at least one filter media body curved in sections provided a curved filter media body having a curvature that extends over an angular span larger than 90 degrees.

6 . The filter element according to claim 1 , wherein
the curvature of the if the at least one filter media body curved in sections provided a curved filter media body having a curvature that extends over an angular span less than 45 degrees.

7 . The filter element according to claim 1 wherein
a curvature of the if the at least one filter media body curved in sections has a center point of the curvature spaced away from the longitudinal axis of the filter element.

8 . The filter element according to claim 1 , wherein
at least two of the filter media bodies are spaced apart from each other without touching.

9 . The filter element according to claim 1 , wherein
two of the filter media bodies abut against each other, at least in one location.

10 . The filter element according to claim 1 , wherein
at least one filter media body of the filter media bodies is curved convexly outwardly.

11 . The filter element according to claim 1 , wherein
at least one filter media body of the filter media bodies is curved concavely outwards.

12 . The filter element according to claim 1 , wherein
the carrier body is configured as a support lattice.

13 . The filter element according to claim 12 , wherein
the support lattice is configured cylindrically; and wherein the filter media bodies each have a partially circular cross section and engage around the support lattice.

14 . The filter element according to claim 1 , wherein
at least one filter media body of the filter media bodies includes at least one flow aperture supplying or discharging fluid.

15 . A filter device, comprising:
a filter element, including:
a first filter media body; and
at least one second, separately formed filter media body;
wherein the filter media bodies are through-flowable by a to-be-cleaned fluid;
wherein the filter media bodies are arranged on a common carrier body;
wherein the filter media bodies limit an intermediate flow chamber for the fluid;
wherein at least one of the filter bodies is formed at least in sections in a curved manner; and
wherein the filter element has a longitudinal axis; and
a filter housing in which the filter element is received.
