Patent number: 11103816Abstract: A potable water filter for an aircraft galley plumbing system is disclosed. In embodiments, the filter includes a body attachable to a mount via a central threaded attachment stud. The stud is surrounded by a filter mount chamber and encloses a central flow channel allowing outflow from the filter body to an outlet port. Potable water enters the mount through an inlet port including a barrel valve that opens to allow water flow when the filter body is screwed onto the stud, and seals off the filter mount chamber when the filter body is absent. The outlet port includes a check valve to prevent backflow into the filter. The filter body houses a solid block of sintered carbon with a hollow core. Water enters the filter chamber and flows around and through the carbon filter before flowing down to the outlet port. The filter body self-vents at its top.Type: GrantFiled: May 17, 2019Date of Patent: August 31, 2021Assignee: Rockwell Collins, Inc.Inventors: Volkan Keskin, Peter J. L. Burd
