Appl. No.:

11/456099

Inventors:

Michael D. Clausen - Turlock CA, US
Peter Popoff - Modesto CA, US

Assignee:

Parker-Hannifin Corporation - Cleveland OH

International Classification:

B01D 46/00

US Classification:

96 4, 96 6, 96219, 210188, 210436

Abstract:

A filter element () comprising a filter media () and a membrane (). The filter media () 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 () to the outlet side () of the filter element (). The membrane () is permeable to air and impermeable to the liquid and the impurities. The membrane () is positioned to provide a bypass from the inlet side () to the outlet side () of the filter element whereby air intermixed with the fluid will not accumulate on the inlet side () of the filter element ().

Abstract:

A fuel filter includes a housing () with a removable element () mounted therein. The housing has an inlet port () in direct fluid communication with a chamber (). A first outlet port () is in direct fluid communication with a central standpipe (). The standpipe has a flow element () movable therein for controlling the condition of flow openings () in the standpipe. The cover further includes a cover projection () for supporting a projection () on the end cap () of the filter element, which opens flow into the standpipe only when the element is installed. The removable element can include first and second filter media rings () where fluid is introduced between the rings and flows radially inward through the first media to the first outlet port (), and radially outward through the second media ring to a second outlet port (). The second filter media ring () includes a distal end () freely supported with respect to the second end cap and defining a continuous annular passage () into the annular cavity () between the media rings ().

International Classification:

B01D 2708

US Classification:

210232

Abstract:

A fuel filter assembly (10) for filtering diesel fuel includes a filter head (12), a spin on replaceable element (13) and a collection bowl (15) removable from the element. The element includes a casing with a turned-in edge portion at a lower end. An adaptor ring (69) is supported on said edge portion inside the element and includes an annular threaded portion (71). The collection bowl has an outer peripheral wall (74) with an annular threaded portion engaging the threaded portion of the adaptor ring. The outer peripheral wall of the bowl has an annular shoulder abutting the turned-in edge portion of said casing to clamp said casing between the adaptor ring and the bowl, when the bowl is attached to the element. A seal (76) between the shoulder and the casing further serves to hold the element and the bowl in fluid tight relation.

Assignee:

Parker Hannifin Corporation - Cleveland OH

International Classification:

B01D 2708

US Classification:

210232

Abstract:

A filter assembly and associated collection bowl for a single or dual contaminant collection zone arrangement use a self-sealing o-ring in combination with a threaded mating arrangement in order to withstand high pressure differentials. The filter assembly may include an end cap having a plurality of downwardly projecting ribs distinct from a threaded connector ring upon which the end cap rests or the ribs may be integral with the connector ring and separate from the end cap. The lower end of the filter housing includes a number of contaminant channels between adjacent pairs of the ribs, the contaminant channels leading to corresponding contaminant outlets.

US Classification:

210238

Abstract:

A fuel filter assembly includes a housing (12) with a removable element (24) mounted therein. The housing has an inlet port (14) in direct fluid communication with a chamber (18). The outlet port (16) is in direct fluid communication with a central standpipe (22). The standpipe has a flow element (42) movable therein for controlling the condition of flow openings (36) in the standpipe. The element includes projections (88) for engaging recesses (90) in a cover (28) to selectively latch the element and cover together. The cover further includes a cover projection (82) for supporting a projection (78) on end cap (60) of the filter element, which opens flow into the standpipe only when the element is installed. When the element is removed, the flow element prevents the introduction of contaminants into the standpipe.

US Classification:

210234

Abstract:

A fuel filter comprises a head (96) having an inlet (100) and an outlet (102). The head is connected to an element (266) by a nipple portion (186) which has a valve element (196) therein. An actuating projection (222, 272) is engageable with said valve element to open flow through said nipple portion when the correct element is attached hereto. The actuating projection is further supported on a central portion (220, 276) which prevents connection to a nipple portion that extends too far into the element. According to a further embodiment, the filter includes a housing (412) with a removable element (424) mounted therein. The housing has an inlet port (414) in direct fluid communication with a chamber (418). The outlet port (416) is in direct fluid communication with a central standpipe (422). The standpipe has a flow element (442) movable therein for controlling the condition of flow openings (436) in the standpipe.

Abstract:

A top-loading filter housing has a spin-on combination cartridge and cover in a unitary assembly. The cartridge is an annular filter medium surrounding a perforated center tube and supported in an imperforate bottom endcap, being joined by potting compound to provide a consolidated structure. An annular seal is retained in a central opening in the endcap and is sized for a sliding fit on a vertical standpipe, centrally supported in the filter housing. The cover portion of the cartridge is a molded, circular, glass-filled nylon plate having a depending peripheral flange threadedly receivable in the open, upper end of the filter housing. The cover includes a central well in which the filter medium and centertube are received, both being secured and sealed by potting compound so that the cover and cartridge may be replaced as an assembly.
