摘要： A filter element (102) comprising a filter media (106) and a membrane (114). The filter media (106) filters impurities (e.g., water and/or contaminants) from a liquid (e.g., a liquid fuel initially containing impurities) as the liquid passes from the inlet side (110) to the outlet side (112) of the filter element (102). The membrane (114) is permeable to air and impermeable to the liquid and the impurities. The membrane (114) is positioned to provide a bypass from the inlet side (110) to the outlet side (112) of the filter element whereby air intermixed with the fluid will not accumulate on the inlet side (110) of the filter element (102).

摘要： A cartridge filter device having high filtration efficiency, having a long filter life, and capable of being produced at low cost. An out-in-pass-type pleated cartridge filter device has a filtration material, a core, a sleeve, and two end caps (upper and lower lid sections). In a filter material cross-section orthogonal to pleat folding, there are one mountain folding line (a), two valley folding lines (b) on both sides of the one mountain folding line, and two mountain folding lines (c) on both sides of the two valley folding lines. Thus the cartridge filter device includes a letter W-shaped section where there are one low mountain section on the sleeve side, two valley sections on the core side, on both sides of the one mountain section, and two high mountain sections on the sleeve side, on both sides of the two valley sections.

摘要： Expansion resistant filter cartridge assemblies are provided that facilitate filtering of strong solvent solutions. The filter cartridge assemblies generally include a cylindrical filter element defining an outer periphery, an inner periphery and opposed end surfaces, a perforated cage operatively associated with the outer periphery of the filter element, a perforated core operatively associated with the inner periphery of the filter element and having opposed ends and a predetermined length, and an end cap operatively associated with each of the opposed end surfaces of the filter element and bonded to each end of the core. The perforated cage generally includes an expansion region of about 2.5% to about 4% of the total length of the filter cartridge, e.g., a region of axial discontinuity or a plurality of angular struts, to accommodate swelling and/or dimensional expansion of the cage without adversely affecting the integrity of the filter cartridge assembly. Alternatively, an expandable net material may be provided to accommodate expansion/swelling thereof. The core of the filter cartridge assembly is advantageously fabricated from material(s) that resist swelling/expansion when exposed to strong solvent solutions, e.g., glass filled polypropylene, stainless steel and/or a fluorinated aliphatic hydrocarbon.
