A filter element, which has an oval cross-section in a longitudinal direction thereof and includes a circumferential sealing device for, in particular, radially sealing the filter element off from a filter holder for the filter element, wherein the sealing device has two first curvature sections arranged one facing the other and two second curvature sections arranged one facing the other, wherein the first curvature sections each have a first radius of curvature and the second curvature sections each have a second radius of curvature, and wherein the first radius of curvature differs from the second radius of curvature.

Filter element and filter arrangement

A filter holder for a filter element that has an oval-shaped cross section, with a receiving section receiving the filter element, a fluid inlet and a fluid outlet. The fluid inlet is arranged such that an inflow direction of the fluid to be filtered is oriented in the direction of a lateral surface of the filter element in order to separate particles contained in the fluid onto a wall of the receiving section with the aid of centrifugal force.

Filter holder, filter element and filter arrangement

A filter element for a filter for filtration of a fluid is insertable along an insertion direction into the filter. The filter element is provided with a filter medium to be flowed through along a main flow direction. The filter element has a clean side and a raw side. A sealing surface surrounds the filter medium, wherein the sealing surface, interacting with a filter housing of the filter when the filter element is in an installed state in the filter housing, separates the clean side from the raw side. A support edge exerts a force on the sealing surface by interacting with the filter housing of the filter when the filter element is in the installed state in the filter housing. The sealing surface and the support edge are positioned at an acute angle relative to each other.

Filter element with an oblique sealing plane

A filter receptacle () for a filter element () that, transversely to a longitudinal direction (LR) thereof, has an oval cross section, said filter receptacle having a receiving portion () for receiving the filter element (), a fluid inlet () for allowing fluid to be filtered (L) into the filter receptacle (), and a fluid outlet () for discharging the fluid (L) filtered with the aid of the filter element () from the filter receptacle (), wherein the fluid outlet () is arranged such that an outflow direction (A) of the filtered fluid (L) from the fluid outlet () is oriented parallel to the longitudinal direction (LR) of the filter element (), and wherein the fluid outlet () has a circular cross section facing away from the filter element () and an oval cross section facing toward the filter element ().

A filter holder () for a filter element () has an oval-shaped cross section, a receiving section () for a filter element (), a fluid inlet (), and a fluid outlet (). The fluid inlet () is arranged such that an inflow direction (E) of the fluid (L) to be filtered is oriented in the direction of a lateral surface () of the filter element () such that the fluid (L) to be filtered flows tangentially around the filter element () in order to separate particles () contained in the fluid (L) onto a wall () of the receiving section () with the aid of centrifugal force.

A filter element (), which has an oval cross-section in a longitudinal direction (LR) thereof and includes a circumferential sealing device () for, in particular, radially sealing the filter element () off from a filter holder () for the filter element (), wherein the sealing device () has two first curvature sections () arranged one facing the other and two second curvature sections () arranged one facing the other, wherein the first curvature sections () each have a first radius of curvature (R, R) and the second curvature sections () each have a second radius of curvature (R, R), and wherein the first radius of curvature (R, R) differs from the second radius of curvature (R, R).
