Patent number: 10913018Abstract: 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.Type: GrantFiled: June 5, 2017Date of Patent: February 9, 2021Assignee: Baldwin Filters, Inc.Inventors: Jonathan D. Moore, Steven J. Merritt
