Appl. No.:

10/734498

Inventors:

Laurence Bassett - Killingworth CT, US
William Contaxis - Milford CT, US
Bruce Taylor - Kensington CT, US
David Carbo - East Haddam CT, US

International Classification:

B01D035/157

US Classification:

210/234000, 210/235000, 210/418000, 210/443000

Abstract:

Disclosed is a unique filter assembly for ensuring replacement cartridge compatibility in filtration systems having replaceable filter cartridges with lugged mounting systems. One representative filter assembly includes a representative cartridge member having a body portion for enclosing filter media and a neck portion depending therefrom. The representative neck portion of the representative cartridge includes at least one axial inlet port for directing unfiltered fluid into the body portion and at least one axial outlet port for directing filtered fluid out of the body portion. The representative neck portion also has at least two representative lugs depending radially outwardly therefrom, wherein at least one lug defines a keyed engagement surface, a leading inclined cam surface and a trailing inclined cam surface. The at least two representative lugs wherein at least one lug defines a keyed engagement surface, a leading inclined cam surface and a trailing inclined cam surface could be operatively positioned on other components of the representative filter assembly as well.

Filed:

Oct 29, 2004

Appl. No.:

10/976571

Inventors:

Laurence Bassett - Killingworth CT, US
William Contaxis - Milford CT, US
Brian Tubby - Cheshire CT, US

International Classification:

B01D035/00

US Classification:

210418000, 210444000

Abstract:

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. The seal member sealingly isolates untreated and treated fluid streams flowing through the inlet and outlet paths of the valve member, respectively, when the valve member is in the filter position, and sealingly isolates the inlet and outlet passages of the head member from the atmosphere when the valve member is in the bypass position to permit fluid to flow therebetween.
