20090250390 | Filter - A filter is disclosed. The filter comprises a canister, filter media disposed within the canister, the filter media having a first axial end, a second axial end and circumscribing a central axis and an end cap having an inner radial surface disposed adjacent the first axial end of the filter media, the end cap defining a centralized axial passage therethrough having a sidewall surrounding said passage that extends to a valve actuation portion that is axially offset from the inner radial surface of the end cap, wherein the actuation portion includes at least one cross member that extends from a position on the sidewall across the centralized axial passage, the cross member having a first radial surface closer to the inner radial surface of the end cap than a second radial surface, and wherein the first radial surface of the at least one cross member is substantially planar. | 10-08-2009 |
20100038305 | Filter - A filter is disclosed. The filter includes a sheet of filter media defining a body having an upper portion, a lower portion, a first end surface proximate the upper portion, a second end surface proximate the lower portion, and a first side surface extending between the first and second end surfaces. One or more of the upper and lower portions define a ledge, wherein the ledge defines a third end surface arranged between the first and second end surfaces, and a second side surface extending between the first and third end surfaces; and a seal disposed upon the ledge. A method for manufacturing the seal is also disclosed. | 02-18-2010 |
20110041315 | Fluid Filter Element - A filter element is removably positionable within a filter housing defining a filter chamber for said filter element. The filter housing comprises a standpipe extending within the filter chamber. The filter element includes a tubular filter media circumscribing the standpipe, a first end cap supporting the filter media at one end thereof, a second end cap longitudinally spaced from the first end cap and supporting the filter media at the opposite end thereof, and a center tube extending between the first and second end caps. The center tube has at least one inlet opening therethrough at a first end thereof adjacent to the first end cap and a standpipe opening therethrough at a second end thereof adjacent to the second end cap. The second end cap has at least one intake opening therethrough radially spaced from the standpipe opening in the center tube. | 02-24-2011 |
20140061137 | Endcap Bypass Plug, Endcap Assembly and Filter Assembly - An endcap bypass plug is disclosed. The endcap bypass plug includes a body and a plurality of leg members. The body includes an upper surface, a lower surface and an outer side surface joining the upper surface to the lower surface. A central axis extends through an axial center of the body. The plurality of leg members are connected to and extends away from the upper surface of the body. Adjacent leg members of the plurality of leg members are spaced apart by a distance to thereby form a plurality of radial passages defining a plurality of radial fluid-flow paths there between. Each leg member of the plurality of leg members includes: a head portion having an upper surface. The head portion includes a nose portion extending radially outwardly from the head portion. The nose portion includes a ramp surface and a lower surface. The ramp surface of the nose portion is connected to the upper surface of the head portion to define an upper edge. The ramp surface of the nose portion is connected to the lower surface of the nose portion to define a lower edge. An endcap assembly is also disclosed. A filter assembly is also disclosed. A method is also disclosed. | 03-06-2014 |
20140166570 | Fluid Filter Element - A filter element is removably positionable within a filter housing that includes a standpipe extending therewithin and provided with a flow control valve.
