Abstract
A filter assembly may include an outer insert and an inner insert. The outer insert having an aperture and a plurality of outer grooves. The outer grooves are formed in a radially outer periphery of the outer insert and are separated from each other and the aperture. The inner insert may be disposed within the aperture. A plurality of inner grooves may be formed in a radially outer periphery of the inner insert. Each of the outer and inner grooves may have a closed axial end and an open axial end.
Claims26
A filter assembly comprising:
- a cylindrical outer insert having an aperture and a plurality of outer grooves, the outer grooves are formed in a radially outer periphery of the outer insert and are separated from each other;
- and
- a cylindrical inner insert disposed within the aperture and having a plurality of inner grooves formed in a radially outer periphery of the inner insert, each of the outer and inner grooves having a closed axial end and an open axial end.
An edge filter assembly comprising:
- an outer insert having a cylindrical first body and first and second flanges disposed at axial ends of the first body, the outer insert including an aperture extending through the first body and the first and second flanges, the outer insert including a plurality of outer grooves, the outer grooves are formed in a radially outer periphery of the outer insert and are separated from each other, the first body having an outermost diameter that is smaller than outermost diameters of the first and second flanges;
- and
- an inner insert disposed within the aperture and having a cylindrical second body and third and fourth flanges disposed at axial ends of the second body, the third and fourth flanges are pressed into engagement with a diametrical surface of the aperture, the inner insert including a plurality of inner grooves formed in a radially outer periphery of the inner insert, each of the outer and inner grooves having a closed axial end and an open axial end, the second body having an outermost diameter that is smaller than outermost diameters of the third and fourth flanges, wherein surfaces defining the inner grooves cooperate with the diametrical surface of the aperture to form a plurality of fluid channels.
