  • Patent number: 11358090
    Abstract: A straight-through flow filter element is provided in which an L-shaped ring is spaced from one of the inlet and outlet flow faces. The seal member may extend therefrom in a cantilevered manner away from one of the flow faces. The spacing may be facilitated by way of spacer elements which may contact the flow face and thereby also support the flow face toward the outer perimeter.

  • Publication number: 20210129056
    Abstract: The filter cartridge locking assembly is configured to secure a collar within a housing of a filter cartridge. The collar includes first and second ends and fits into a circumferential retainer included on the housing. At least one notch is formed between the first and second ends of the collar for mating with at least one complimentary bead included on the retainer. An annular gap is defined on the collar for receiving a portion of the retainer. The retainer also receives a portion of the collar. The retainer is comprised of a first leg that extends radially outwardly and a second leg that extends substantially perpendicular to the first leg. The first and second legs interact with the collar in a surface-to-surface relationship while the at least one bead engages the at least one notch to form an axially and rotationally locked coupling between the housing and the collar.

  • Patent number: 10913018
    Abstract: A filter element for use in a housing of a filter assembly having a cover and a seal therebetween. The housing includes inlet and outlet valves. The filter element comprises a first endcap and a second endcap including an inlet valve actuator. A cylindrical ring of filter media extends axially between the first and second endcaps and surrounds a center tube that defines an outlet having an outlet valve actuator. A sleeve positioned to receive and exert force in a first and second direction surrounds a bias member. Threading the cover to the housing compresses the bias member causing the inlet and outlet valve actuators to actuate the inlet and outlet valves. Removing the cover causes extension of the bias member and the inlet and outlet valve actuators to retreat from the inlet and outlet valves before the seal between the cover and the housing is broken.
