  • 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.

  • Patent number: 11111889
    Abstract: A recirculation module for a fuel prefilter unit of a combustion engine has a temperature-controlled actuating element that transfers the recirculation module, based on a filter raw side feed temperature of the fuel, from a cold start state into a normal operating state and back. In cold start state, an engine return line from the combustion engine to the recirculation module is in fluid communication with a filter element raw side of the fuel prefilter unit and the engine return line is separated in regard to fluid communication from a tank return line of the combustion engine. In normal operating state, the engine return line is separated in regard to fluid communication from the filter element raw side and is in fluid communication with the tank return line. A check valve prevents return flow of fuel from the tank return line into the engine return line.
