Abstract: A filter assembly and associated filter unit includes a repelling-action filter media for use in vacuum or suction side fuel filter applications. In particular, the filter unit is a screw on unit with centrally located threads at opposite ends of the filter unit and with a specifically designed end cap allowing use of the filter unit with a dual zone collection bowl normally used for coalescing pressure side filter applications. The end cap includes holes which allow use of both of the collection zones in spite of the normal isolation between the collection zones.

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.

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.

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.

Abstract: A fuel filter assembly for diesel fuel includes a filter head structure, spin-on replaceable element and threaded collection bowl. An annular heater housing is secured in the filter head for warming the fuel prior to passage through the filter medium with a pair of positive temperature coefficient heater discs providing the self-regulating heater function. A check valve is housed in the inlet chamber of the filter head in bypass connection with the filter medium to vent air from the chamber and to establish a return path for fuel from the filter. A restrictive orifice in the check valve limits fuel flow in the bypass path and an elastomeric duck-bill type valve provides the check valve function.

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. The cover further includes a cover projection (482) for supporting a projection (478) on end cap (460) of the filter element, which opens flow into the standpipe only when the element is installed. A centering wall (486) is also provided on the cover which is received within a recess portion (704) of a well area of the end cap (460). The removable element can include first and second filter media rings (426, 716) where fluid is introduced between the rings and flows radially inward through the first media to a first outlet (416), and radially outward through the second media ring to a second outlet (710).

Abstract: A fuel filter has a semipermeable spiral baffle with an open circuitous spiral channel between spiral flights of filter media. Fuel may pass radially (inwardly or outwardly) through the media which preferentially slows water and other contaminants such that the contaminants tend to "settle" in the channel and slowly flow out of the baffle to a contaminant collection zone.

Abstract: A filter unit uses an end cap design to allow flow reversal from inside-out or outside-in and accommodates a dual collection zone or sump collection bowl. The spin-on filter unit has relieved portions on the end cap to define contaminant channels such that the space between an annular filter media and the filter unit housing is connected to one of the sumps. The contaminant channels allow for prefiltering contaminant removal when the filter connected for radially inward flow and allows for post filtering contaminant removal when the filter unit is connected for radially outward fuel flow.
