Abstract: A filter assembly that includes a water separator as part of the filter assembly. The water separator is arranged in the filter assembly and includes a filter element that is provided with a hydrophobic medium through which fuel/lubricant can pass through. The filter assembly also includes a water separator positioned downstream from the filter element. During the operation of the filter assembly, the water separator causes the water in the fuel to be separated and accumulate on the hydrophobic surface of the water separator and, due to the gravity, allows the water to flow downwards along the surface of the water separator into a water collection/sedimentation chamber where it can be evacuated from the filter through one or more passageways.

Abstract: A fluid filter assembly is adapted to filter out contaminants from a fluid supply. The filter assembly includes a housing that is adapted to house a cylindrical filter element. The housing includes a lower housing and an upper housing. A top plate is secured to the upper filter housing. Both the top plate and upper filter housing include seals that are adapted to seal the filter. The filter includes threads formed on an exterior surface of the upper housing to allow the filter to be coupled to a filter mount. Dirty fuel enters the filter through the top plate by use of a plurality of openings formed in the top plate, passes through media of the filter element, and exits through a center opening formed in the top plate.

Abstract: A filter for filtering contaminants from a fluid. The filter includes a cylinder of pleated filter media, a first end cap coupled to a first end of the filter media and a second end cap coupled to a second end of the filter media. The second end cap including a wall formed to include a central opening. The filter also includes a central core positioned radially inward of filter media and extends from the first end cap to the second end cap. The central core has a cylindrical side wall that is formed to include a plurality of apertures that are adapted to allow for the passage of the fluid. The filter also includes an annular collar that is adapted to be positioned within the central core. The annular collar is adapted to be rotatable with respect to the central core and includes a sidewall formed to include a series of space projections that extend radially inwardly from the sidewall.
