Pressure Resistant Filter Cartridge

摘要

A fuel filter cartridge includes a housing having first and second shell sections. The shell sections are generally symmetric about a cartridge axis and joined together. The first shell section has a convex-shape when viewed from a side and includes an end portion, a cylindrical side wall portion, and a transition portion connecting the side wall portion to the end portion. The end portion has an end surface forming a cartridge opening coaxial with the cartridge axis. The transition portion has a radius of 0.125-1.125 inches. A filter having at least one filter element is disposed within the housing.

1. A filter cartridge comprising:
a housing including first and second housing sections generally symmetrically disposed about a longitudinal axis and joined at a circumferential shoulder to define an interior volume extending between first and second ends of said housing, said first housing section including a grommet support clip projecting into said interior volume, said grommet support clip defining a fluid flow opening coaxial with said longitudinal axis, said first housing section including a generally continuous first side wall portion with a first side wall first end adjacent said circumferential shoulder, said first side wall portion having a first diameter at a first longitudinal position and said first housing section including a first transition portion extending radially inwardly relative to said first wall portion at said first longitudinal position to said grommet support clip, said first transition portion defined by a radius rotated about a point within said interior volume, rotation of said radius subtending an obtuse angle; said second housing section including a generally cylindrical second side wall having a second diameter larger than said first diameter, said second side wall extending between said circumferential shoulder and a second transition portion at said housing second end, said second transition portion extending radially inwardly from said second side wall; a grommet captured by said grommet support clip, said grommet extending from an upper shoulder outside said interior space to a lower shoulder projecting into said interior space; and filter media supported within said interior space for filtering fluid passing through said filter cartridge, wherein said housing is imperforate other than said fluid flow opening and configured to contain a fluid to be filtered.
