    Abstract: The present invention provides a multi-element filtering system assuring serial filtration of a liquid through multiple filter cartridges while enabling flushing without requiring removal of the filter cartridges. Both conventional and reverse osmosis filtration is performed, sequentially, within the system. After filtration, the water is subjected to ultraviolet irradiation for purification. The filter cartridges are held within a canister which is pressed against the cap and constrained against rotation with the cap. The canister is divided into chambers, and has passages in its floor arranged to enable serial transfer of liquid from one chamber to the next. Flushing employs liquid introduced under normal pressure. Passages leading to the flush liquid outlet enable flushing to proceed when the flush liquid outlet is opened. At other times, filtered liquid will pass through passages leading to the filtered liquid outlet. Liquid is circulated to assure filtration even when flushing, so that contamination of filtered liquid is precluded.

    Abstract: A filter system especially useful in the treatment of waste material, in particular liquid waste material which may include particulate matter therein. The filter system includes a series of filters of progressively finer porosity in order to selectively eliminate particulate (or semi-particulate) matters from a carrier material, typically, but not exclusively, of a fluid or liquid nature. The filters are mounted within a housing which includes one or more inlet ports and at least one outlet port.

    Abstract: A fuel 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). A first 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 the end cap (460) 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 (426, 716) where fluid is introduced between the rings and flows radially inward through the first media to the first outlet port (416), and radially outward through the second media ring to a second outlet port (710). The second filter media ring (716) includes a distal end (728) freely supported with respect to the second end cap and defining a continuous annular passage (732) into the annular cavity (726) between the media rings (426, 716).

    Abstract: The present invention relates to an arrangement in an oil filter with integral oil cooler with a filter material (7) in the form of a tubular casing, which is enclosed in a housing (1). The latter is defined by a cylindrical wall (4) and two ends (5, 6), one (5) of which can be opened for changing the filter material (7). Two essentially concentric annular circulation chambers (8, 9) are arranged in front of the cylindrical wall. Of these the one that connects with the inside of the housing (12) is intended to accommodate the flow of oil and the other which has an inlet opening (10) and an outlet opening (11) is intended to accommodate the flow of coolant. The coolant circulation chamber (8), which is the outer of the two circulation chambers, is divided by a partition wall (25) into two essentially equal sub-chambers (8a, 8b) into each of which an opening (10, 11) respectively opens. In the partition wall (25) there is a passage (19a) connecting the sub-chambers (3a, 3b), the passage being situated equidistant from the mouths (10, 11) of the inlet and outlet openings in the sub-chambers (8a, 8b), in order to obtain a symmetrical flow of coolant in the circulation chamber (8).

    Abstract: A filter assembly including a filter housing having a standpipe extending upwardly therethrough, in which is located a spring-biased flow element, and about which is received a replaceable filter element. A screw threaded cover is removably attached to the housing. The filter element includes an upper endcap, a center tube, a lower endcap and cylindrical filter media around the center tube. The lower endcap includes a central opening which receives upwardly therethrough the standpipe in sealed relation. A separate actuator with a projection formed to extend therefrom is located in the center tube, either fixedly or movably, below the upper endcap. When the filter element is placed over the standpipe, and the cover attached to the housing, the projection on the actuator pushes down against the spring-biased flow element, putting cavities formed in the flow element and openings formed in the standpipe in fluid communication. This alignment allows fluid to flow between an area inside the media adjacent the standpipe, to the interior of the standpipe, and out an outlet port of the housing. When the filter element is removed from the housing, for replacement with a new filter element, the projection is removed from the flow element, which returns to its original position to prohibit the fluid communication.

    Abstract: A water filter assembly mounted to an inner surface of a refrigerator and accessible from within a refrigeration compartment of the refrigerator. The filter assembly includes a first housing part, a second housing part, and a replaceable filter cartridge. The first and second housing parts cooperate to define a fluid-tight chamber for receipt of the filter cartridge. The first housing part includes an inlet port through which unfiltered water may be introduced into the chamber and an outlet port through which filtered water may exit the chamber. The second housing part surrounds a portion of the first housing part and provides a volume sufficient to hold the filter cartridge and any water within the chamber when the second housing part is released from the first housing part to replace the filter cartridge, and thereby prevents or minimizes spillage of water from the filter assembly during filter cartridge replacement. A shield member is disposed within the refrigeration compartment and cooperates with a cabinet wall to define a filter compartment which surrounds the filter assembly. A heater disposed within the filter compartment adjacent the filter assembly and is operable to heat the filter assembly to prevent freezing of water contained therein.
