Fuel filter assembly with replaceable element having integral cover

A filter assembly comprising:

• a housing including a chamber, the housing including an opening to said chamber, said chamber bounded by a generally longitudinally extending, imperforate annular wall adjacent said opening;
• a first fluid port and a second fluid port;
• said second port being connected to said chamber through an aperture in said annular wall;
• a removable filter element in said chamber, said filter element
• a ring of media having at least one open end,
• a disk-shaped body adhesively attached to said media ring at said open end and having a central portion extending radially inwardly beyond a radially innermost annular interior surface of said media ring adjacent said open end of said media ring;
• and
• an annular resilient radially extending deformable portion in fluid tight connection with said disk-shaped body and extending radially outward beyond said media ring, said deformable portion being deformably engageable circumferentially with said longitudinally extending annular wall, and said disk-shaped body including a fluid passage communicating at one end to an interior of said media ring and opening at its other end to a radially outer wall of said disk-shaped body;
• and
• wherein said disk-shaped body is externally threaded at its outer diameter, whereby the filter element may be screwed into said housing.

A removable filter element for a liquid filter assembly, said assembly including a housing having an inlet port means and a chamber means, the chamber means having an opening, and said chamber means bounded by a generally longitudinally extending annular wall adjacent said opening, one of said port means in fluid communication with a first aperture in said annular wall, said element comprising:

• a closure portion for closing said opening, said closure portion being externally threaded at its outer diameter, whereby the filter element is screwable into the housing;
• a dividing means for fluidly dividing said chamber means, said dividing means longitudinally disposed from said closure portion and adapted for dividing a first area from a second area, said dividing means including resilient annular radially extending deformable engaging means for deformably engaging said annular wall circumferentially;
• filter media loop means adhesively attached at an open end thereof to said dividing means for removing contaminants from liquid flowing therethrough, said media loop means fluidly disposed between said first and second areas, said dividing means having a central portion surrounded by said deformable engaging means, said central portion longitudinally spaced from said closure portion and extending radially inwardly beyond a radially innermost annular surface of said media loop means adjacent said open end of said media loop means and including one end of a fluid passage connected to an interior area of said media loop means, and said fluid passage having an end opposite said interior area opening to a radially outer wall of said dividing means.

A filter element comprising:

• a ring of media having at least one open end,
• a disk-shaped body adhesively attached to said media ring at said open end and having a central portion extending radially inwardly beyond a radially innermost annular interior surface of said media ring adjacent said open end of said media ring;
• and
• an annular resilient radially extending deformable portion in fluid tight connection with said disk-shaped body and extending radially outward beyond said media ring, said deformable portion being deformably engageable circumferentially with a longitudinally extending annular wall of a filter housing, and said disk-shaped body including a fluid passage communicating at one end to an interior of said media ring and opening at its other end to a radially outer wall of said disk-shaped body;
• and
• wherein said disk-shaped body is externally threaded at its outer diameter, whereby the filter element may be screwed into the filter housing.

A removable filter element acceptable in a filter housing, said housing having a longitudinally extending, imperforate annular wall, said annular wall bounding a chamber formed therein, said chamber having an opening adjacent a longitudinal end of said wall and a closed end opposite said opening in said housing, said housing further including an inlet port and an outlet port, said inlet port fluidly connected to said chamber through a first aperture in said annular wall, and said outlet port fluidly connected to said chamber through a second aperture in said annular wall, said element comprising:

• a closure portion for closing said opening, said closure portion being externally threaded at its outer diameter, whereby the filter element is screwable into the housing;
• a disk shaped member, said disk shaped member longitudinally disposed from said closure portion and adapted for fluidly dividing a first area from a second area in said housing, wherein said first area includes said first aperture and said second area includes said second aperture, said disk shaped member including a radially outward extending lip portion deformably engageable with said annular wall circumferentially;
• and
• a ring of filter media adhesively attached to said disk shaped member enabling removal of contaminants from liquid flowing therethrough, wherein said media is fluidly disposed between said first and second areas, and said disk shaped member extends radially inwardly beyond a radially innermost annular surface of said filter media at an adjacent open end of said filter media partially closed by said disk shaped member.
