Abstract: A fluid filter device is described, where a flow attachment member provides a unique interface between the filtering element and a filter head. The fluid filter described herein generally provides a flow structure that is localized and sealed. The flow attachment member is configured to communicate fluid into and out of the fluid filter, and is configured to localize fluid flow both into and out of the fluid filter within a separating structure of the flow attachment member. The flow attachment member further includes a seal structure configured to substantially prevent or at least confine leakage to a localized area away from proximity of the edges of the housing. A composite filter head is described that has integrally molded inlet and outlet fittings.

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.

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.

Abstract: A separation assembly is generally described that can chemically treat condensate material in a fluid stream. One particular example of a separation assembly is a crankcase filtration assembly used in engine oil filtration and that includes an additive material disposed within the crankcase filtration assembly. The additive material chemically treats condensate material of blow-by fluids received by the crankcase filtration assembly when a condition is present in the condensate material. For example, the crankcase filtration assembly provides a unique structure with a chemically treated component that can reduce an acidic condition in condensate material received by the crankcase filtration assembly, and even more generally may extend engine oil life.

Abstract: Described herein are embodiments of a fluid filter for combustion engine systems and associated methods. According to one exemplary embodiment, a fluid filter apparatus for reducing re-entrainment of contaminant particles into post-filtration fluid flow due at least in part to a fluid flow surge includes at least one fluid filter and a fluid flow diverting element that is coupled to the fluid filter. The fluid filter includes at least one fluid filtering medium that is communicable in fluid flow receiving communication with a fluid flowing along a first fluid flow path during a fluid flow non-surge event. During a fluid flow surge event, the fluid flow diverting element is capable of diverting at least some of the fluid from the first fluid flow path to a second fluid flow path.

Abstract: A filter assembly is provided that includes an immobilized base material in combination with a slow release mechanism for introducing an additive base material into a lubrication fluid flowing through the filter assembly. The introduced base material is a weaker base material than the base material of the immobilized base material. The combination of the immobilized base material and the additive base material provides a system that would work to neutralize acids for all lube formulations commonly used in the field. As a result, oil drain intervals can be extended.

Abstract: A pressure gradient dosing system is provided for a fluid supply system. A flow passage has first and second pressure zones having a pressure gradient therebetween. An additive reservoir in an additive delivery system responds to the pressure gradient to release additive to the flow passage.

Abstract: The present invention provides a filter assembly containing a filter element and a container as a depot for a liquid additive. The container can include an inlet and an outlet, which are configured to allow a liquid to flow into the container mix with the contained additive and then flow out into the system. It has been observed that a liquid flowing through a filter assembly exhibits a pressure gradient within the filter. Consequently, the inlets and outlets to the container can be positioned to take advantage of the pressure gradient to enhance the addition of the additive to the liquid in the filter assembly.
