  • Controlled release of additives in fluid systems
    Patent number: 7581558
    Abstract: A container (1) for releasing a chemical additive (7) in a fluid material selected from a lubricant or hydraulic fluid composition comprises a fluid material-impermeable casing (3) having a hollow interior and an additive composition (7) comprising at least one fluid material-soluble additive. The additive (7) is held within the container (1) by a least one fluid material-permeable element (11) provided at or near an opening (13) in the casing (1) and is effective to provide for release of additive(s) (7) into the fluid material. Methods of releasing additives (7) into fluid material are also provided.

  • Filtration device with releasable additive
    Patent number: 7563368
    Abstract: A filtration device is provided that includes a filter component and an additive component. The filter component includes concentrically arranged filtering elements disposed in a filter-in-filter configuration. The additive component includes at least one additive material that is introduced into a working fluid to be filtered. The filter component and additive component provide an assembly for a filtration system that would filter a variety of working fluids. The filter component and additive component provides an assembly that can filter fluids more efficiently. As a result, fluids may enjoy, for example, extended drainage intervals and thereby reduce component wear.

  • Apparatus, system, and method for multistage water separation
    Patent number: 7527739
    Abstract: An apparatus, system, and method are disclosed for multistage water separation. A first separation layer separates water droplets from a fuel flow by repelling the first water droplets. A coalescing layer may coalesce fine water droplets in the fuel flow. In one embodiment, a centrifugal separator directs the fuel flow tangentially to a filter wall and the centrifugal force of the fuel flow directed tangentially along the filter wall biases water droplets from the fuel flow. A second separation layer separates second water droplets from the fuel flow.

  • Filter with protruding member for engaging valve in head
    Publication number: 20080283463
    Abstract: A fuel filtration apparatus for use in an internal combustion engine comprises an interrupter valve in a flow path from an inlet port of a filter head to a compliant filter. The interrupter valve has an open state and a closed state. In the open state a protruding member of the filter depresses a bottom end of the valve and opens the flow path when the compliant filter is connected to the filter head. The interrupter valve also has a closed state wherein the flow path is closed in the absence of the protruding member of the filter (as with a non-compliant filter).
