Abstract: A filter element may include a tubular member including a partition at least partially defining first and second chambers. The tubular member may further include at least one outlet aperture and at least one inlet aperture configured to provide flow communication exiting from the first chamber and flow communication into the second chamber, respectively. The filter element may be configured such that fluid passing through the filter element from an inlet port to an outlet port passes through the first chamber, a filter medium, and the second chamber. The filter element may also include an end cap having a return aperture configured to provide flow communication between fluid exiting from the first chamber and fluid entering the inlet port, wherein a portion of fluid exiting from the first chamber is returned to the inlet port for recirculation through the first chamber.

Abstract: A filter assembly in housing 11 into which a thixotropic fluid is injected for filtration comprises filter layer 14c that is positioned along the central axis and which has the finest mesh, said filter layer 14c being surrounded successively in order by middle filter layer 14b having the next finest mesh and outer filter layer 14a of a coarse mesh. The thixotropic fluid injected into the housing passes through layers 14a, 14b and 14c in that order, whereby the fluid flows out of the housing through one stage of filtration steps.

Abstract: A filter for liquids is disclosed, which has a base with a central inlet, and an outlet, a central post with a filtering element surrounding and sealing therewith, a cannister enclosing the element and releasably sealed to the base, a passageway in the post, which is sealed to the inlet, and which has means to permit upward flow but inhibit downward flow or drip. This retains the liquid in the cannister and element when drawn upwardly, to prevent drip or spillage, or when lowered to provide a full prime. A method of removing the filtering element without drip, and a method of installing a primed element are also disclosed.

Abstract: A fuel filter includes a housing made of plastics and having a main housing portion accommodating a filter element, and a cover. The housing portions are tightly connected to each other at a single ring-shaped glue spot. The housing portion is formed with a pocket filled with glue and the cover is formed with a collar partially projecting into the pocket to form an annular Z-shaped gap in which the glue is distributed. When the glue is solidified the housing and the cover become rigidly and tightly connected to each other. The shape of the gap protects the glue against aggressive fuel.

Abstract: A filter assembly having a first stage filter that filters particulates from fluid flowing through the filter and a second stage filter downstream of the first stage filter that coalesces water from the fluid. By providing the first stage filter upstream of the second stage filter, particulate filtration capacity and efficiency may be provided while protecting the second stage filter from particulates. Protecting the second stage filter from particulates allows for the life of the second stage filter to be extended while providing efficient emulsion removal in the filter assembly.
