Publication number: 20220339560Abstract: A fluid filter assembly includes a housing, a proximal end cap, and a nut plate. The housing defines a longitudinal axis and includes an inner surface. The inner surface surrounds the longitudinal axis and defines a hook portion. The proximal end cap is disposed within the housing and includes a flange engaging the inner surface of the housing. The nut plate is disposed within the housing and includes a proximal end and a distal end. The proximal end engages the hook portion of the housing. The distal end engages the proximal end cap.Type: ApplicationFiled: July 11, 2022Publication date: October 27, 2022Applicant: MANN+HUMMEL Filtration Technology US LLCInventors: James Michael Glazewski, Matthew Robert Hudson, David Brent Harrelson

Patent number: 10507413Abstract: An apparatus configured to engage a filter housing and an end of filter media includes an endcap and at least one biasing portion. The endcap includes a first axial surface, a second axial surface arranged opposite said first axial surface, and an outer radial surface transverse to the first and second axial surfaces. The first axial surface is configured to engage the end of the filter media. The at least one biasing portion includes a proximal end integrally formed with the endcap, and a distal end extending radially outward of the outer radial surface.Type: GrantFiled: January 17, 2017Date of Patent: December 17, 2019Assignee: MANN+HUMMEL Filtration Technology Group Inc.Inventor: David Brent Harrelson

Patent number: 10369502Abstract: A spin-on filter includes a housing and a cover plate defining a central opening. The housing has a closed end a circumferential wall extending from the closed end to an open end and circumscribes an internal chamber configured to receive a filter element. The cover plate includes a substantially planar outer surface extending radially outward from the central opening to an outer circumferential wall. The spin-on filter also includes a series of engagement tabs integrally formed with one of the outer circumferential wall of the cover plate or the interior wall of the housing. Each engagement tab is configured to mate with corresponding ones of a series of receiving slots formed within the other one of the outer circumferential wall of the cover plate or the interior wall of the housing when the cover plate and the housing are axially pressed together to secure the cover plate to the open end of the housing.Type: GrantFiled: January 10, 2017Date of Patent: August 6, 2019Assignee: MANN+HUMMEL Filtration Technology Group Inc.Inventors: David Brent Harrelson, James Michael Glazewski, Matthew Robert Hudson
