Patent number: 8246883Abstract: A filter cartridge includes a one-piece housing having a port and a filtration element disposed in the housing. The filtration element is a coherent filter block that can be larger in cross dimension than the port. The filtration element can be a coherent filter block that generally conforms to the shape of the hollow interior, but is slightly smaller than the hollow interior so as to define a gap between the filtration element and the inner surface. One method for constructing a filter cartridge includes providing a housing having a hollow interior and at least one port, introducing a granular material into the hollow interior via the port, and transforming the granular material in the hollow material into a coherent filter block. Another method for constructing a filter cartridge includes providing a filtration element in the form of a coherent filter block, and overmolding a housing around the filtration element.Type: GrantFiled: June 9, 2008Date of Patent: August 21, 2012Assignee: 3M Innovative Properties CompanyInventors: Laurence W. Bassett, William Contaxis, III, Karl J. Fritze, Mahesh Z. Patel

Patent number: 7407148Abstract: A valve assembly is disclosed for use in conjunction with a replaceable filter cartridge system. The valve assembly includes a head member having an interior valve chamber defining a central axis, and inlet and outlet passages extending parallel to and communicating with the interior valve chamber. The valve assembly further includes a valve member having an inlet path and an outlet path, adapted for rotation within the interior valve chamber of the head member between a filter position wherein the inlet path of the valve member is in communication with the inlet passage of the head member and a bypass position wherein the inlet path of the valve member is out of communication with the inlet passage of the head member. The valve assembly further includes a seal member seated in an upper surface of the valve member and positioned to seal against an opposing surface of the interior valve chamber.Type: GrantFiled: October 29, 2004Date of Patent: August 5, 2008Assignee: 3M Innovative Properties CompanyInventors: Laurence W.
