Abstract: A fluid filter assembly of a filtration system is described. The filter assembly described includes a cover member and a filter cartridge having at least one filter element and a plate member. The plate member includes a seal surface on one side facing the cover member, and a seal surface on another side facing away from the cover member. The seal surface facing the cover member is configured to seal with the cover member, and the seal surface facing away from the cover member configured to seal with another component of the filtration system. The assembly provides a structure that can retain a seal between sealing surfaces of the cover and the filter cartridge, at least while the fluid filter assembly is being serviced, so as to at least minimize fluid dripping and leakage.

Abstract: The combination of a gas-pressure-driven pump jet nozzle or alternatively Coanda effect nozzle with an impactor nozzle(s) in an air-oil separator for separating oil from blow-by gasses from a crankcase of an internal combustion engine, or for separating liquid aerosol from gas, in general. Such combination enhances impaction efficiency and enables operation at higher pressure differentials (or pressure drop) (“dP”) without causing excessive backpressure in the air-oil separator.

Abstract: Described herein is a continuous process for modifying the properties of polyester and polyester based fibers, such as a poly(butylene terephthalate) (PBT) fiber, comprising subjecting the PBT fiber to alkaline hydrolysis, and optionally further comprising functionalizing the PBT fiber by solution grafting such as fluorination. The alkaline hydrolysis and optionally subsequent functionalization such as fluorination process can be continuous, following the melt blowing/spinning or spun-bonding process. Also described is a nonwoven PBT fiber mat obtained by the surface modification process. Further described is a filtration device comprising the nonwoven PBT fiber mat.

Abstract: Composite filter media is formed from multiple layers of media material including a nanofiber media layer, where the layers are laminated, bound, or otherwise composited to each other. The composite filter media can comprise at least one nanofiber layer comprising polymeric media material having a geometric mean fiber diameter of about 100 nm to 1 μm, and fibers configured in a gradient such that ratio of the geometric mean diameter of fibers at the upstream face of the nanofiber layer to the geometric mean diameter of fibers at the downstream face of the nanofiber layer is about 1.1 to 2.8, preferably about 1.2 to 2.4.

Abstract: Disclosed are modular filter-in-filter elements, namely an outer filter element and an inner filter element which may be assembled to form a filter cartridge for use in separation methods and systems. The outer filter element typically functions as a coalescing element and the inner element typically functions as a particulate filter element. The disclosed filter cartridges may be structured for separating water from a hydrocarbon-based liquid fuel as the fuel moves through the cartridge from outside to inside.

Abstract: An axial flow element for use in a liquid separation system for an internal combustion engine includes a hub, a groove, a locking member, and a flat layer. The hub includes a cylindrical outer surface. The groove is disposed in the outer surface. The groove extends in a substantially longitudinal direction along the hub from a first end of the hub to a second end of the hub. The locking member is disposed in the groove. The flat layer is disposed between the hub and the locking member.
