  • Patent number: 11890567
    Abstract: 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.

  • Patent number: 11148088
    Abstract: 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.

  • Publication number: 20200094181
    Abstract: A filter holder (2) for a filter element (3) that has an oval-shaped cross section transverse to a longitudinal direction (LR) thereof, with a receiving section (19) for receiving the filter element (3), a fluid inlet (24) for allowing fluid (L) to be filtered into the filter holder (2), and a fluid outlet (25) for letting the fluid (L) filtered with the aid of the filter element (3) out of the filter holder (2), wherein the fluid inlet (24) is arranged such that an inflow direction (E) of the fluid (L) to be filtered is oriented in the direction of a lateral surface (29) of the filter element (3) that can be received in the receiving section (19), whereby the fluid (L) to be filtered flows tangentially around the filter element (3) that can be received in the receiving section (19) in order to separate particles (33) contained in the fluid (L) to be filtered on a wall (30) of the receiving section (19) with the aid of centrifugal force.
