摘要:
A filter with installation integrity permits fluid flow only in a first installation condition and not in a second undesired or mis-installation condition, including improper alignment or mounting of a filter element in a housing, an incorrect replacement filter element, absence of a filter element, and an incorrect housing cover. A magnetically actuated valve has a piston controlling fluid flow according to installation condition.
摘要:
A filter includes a filter element formed of filter media, and a plastic framework molded and bonded to and structurally supporting the filter media. One embodiment desirably provides a two-component assembly consisting solely of two components, namely the filter media and the plastic framework molded thereon. In a further embodiment, the plastic framework includes a resilient seal integrally molded therewith and of the same plastic material thereof, eliminating a separate component for the seal. In a further embodiment, a filter combination includes a primary filter element and a secondary filter element. In a further embodiment, a resilient integrally molded seal is provided.
摘要:
A filter includes a filter element mounted to a base and having first and second end caps spaced axially along an axis. Fluid to be filtered flows laterally through the filter element and axially through a hollow interior and through an axial flow opening of the second end cap. The filter element is mounted to the base solely by the second end cap in rotational relationship independently of the first end cap, eliminating the third component traditionally needed for mounting a housing cover to the base and enclosing and/or sealing and/or retaining the filter element in the housing.
摘要:
A full flow fluid filter (300, FIG. 15) has a housing (302) extending axially along an axis (304), and a pleated filter element (318) having a plurality of pleats in a closed loop annulus having an outer perimeter (320) defined by a plurality of outer pleat tips, an inner perimeter (322) defined by a plurality of inner pleat tips, and a hollow interior (324) extending along the axis. Fluid flows substantially directly axially through the filter element, with minimal bending and change of direction, minimizing flow restriction.
摘要:
A filter (10, 10a) includes a housing (12, 12a) extending along an axis (14). and having an inlet (16, 16a) at one axial end (18, 18a) of the housing and having an outlet (20, 20a) at a distally opposite axial end (22, 22a) of the housing. One or more pleated filter elements (44, 44a, 44b, 44c, 44d) in the housing are pleated along a plurality of bend lines (46, 48) extending axially. The filter element has a plurality of wall segments (50) extending in serpentine manner between the bend lines. The wall segments extend axially between upstream ends (52) and downstream ends (54) and define axial flow channels (58, 62) therebetween. The upstream ends of the wall segments are alternately sealed (56) to each other to defme a first set of flow channels (58) having open upstream ends (60), and a second set of flow channels (62) interdigitated with the first set of flow channels and having closed upstream ends (64). The downstream ends of the wall segments are alternately sealed to each other (66) such that the first set of flow channels have closed downstream ends (68), and the second set of flow channels have open downstream ends (70). Fluid to be filtered flows substantially directly axially through the filter element (44) or elements (44a, 44b, 44c, 44d), through the open upstream ends of the first set of flow channels then through the wall segments then through the open downstream ends of the second set of flow channels. A gasket (82, 82a, 82b, 82c) seals the filter element to the housing.
摘要:
A corrugated seal for connecting two relatively movable structures and for conducting fluid between the two structures. The corrugations of the seal are arranged at a sloping angle in the direction of fluid flow to prevent the accumulation of fluid in the folds of the corrugations.
摘要:
One embodiment is a filter element including an outer filter media and an inner filter media. The outer filter media is operable to remove particulates present in a flow of fluid and/or coalesce water contained in the flow of fluid. The inner filter media is operable to remove particulates from the flow of fluid, separate water form the flow of fluid, and remove particulates from the flow of fluid. Other embodiments include unique apparatus, devices, systems, and methods relating to fuel filters and filtration. Further embodiments, forms, objects, features, advantages, aspects, and benefits of the present application shall become apparent from the detailed description and figures included herewith.
摘要:
A filter includes a housing with multiple flow passages and filter elements, including at least first and second flow passages therethrough including respective first and second filter elements in parallel. Respective internal dividing walls separate flow passages in space saving relation.
摘要:
A filter is provided by a panel filter element having a perimeter gasket having sealing planes axially between inlet and outlet axial ends of the panel filter element and having a merge point with the panel filter element axially between the sealing planes.
摘要:
A filter includes first and second axially spaced end caps having filter media extending axially between the end caps and extending in a closed-loop around a perimeter defining a hollow interior communicating with an axial flow opening through one of the end caps. One or more columns extend axially in the hollow interior between the end caps and are laterally spaced from the axial flow opening and have hollow sub-interiors for receiving one or more posts extending axially thereinto from a base for mounting the filter to the base in axial compression and with a wiper seal.
