Abstract:
1. A component of a filter element, wherein the filter element includes a tubular filter media circumscribing a central axis; a first end cap supporting said filter media at one end thereof; a second end cap supporting said filter media at the opposite end thereof, the component of the filter element comprising: a tubular member circumscribing a central axis, said tubular member having a substantially cylindrical body defining a passage extending through the tubular member, wherein the substantially cylindrical body extends between an upper end and a lower end, wherein the upper end defines an upper opening, wherein the lower end defines a lower opening, wherein the upper opening and the lower opening permits access to the passage extending through the tubular member, wherein the tubular member defines a plurality of circumferentially arranged intake holes extending through a thickness of said substantially cylindrical body, wherein the thickness of the substantially cylindrical body is a non-constant thickness, wherein the non-constant thickness segments the substantially cylindrical body into at least two segments wherein a first segment of the at least two segments defines a first thickness, wherein a second segment of the at least two segments defines a second thickness, wherein the second thickness is greater than the first thickness, wherein the second segment of the substantially cylindrical body defines a plurality of spaced-apart, radially-inwardly-projecting, circumferentially arranged flow control valve standpipe actuator keys that are offset by a distance from the central axis.
