Abstract: An attachment and retaining mechanism is described for removably attaching a rotating filter element to a rotating shaft. The rotating filter element includes a filter media that is driven by a drive mechanism that rotates the rotating shaft. The filter element is removably attached to the rotating shaft such that the filter element and filtration system can be periodically replaced and/or serviced. In some arrangements, the drive shaft includes a D-shaped section that interacts with a mating section of the filter element sleeve of the rotating filter element. In other arrangements, the drive shaft includes at least one flat drive surface.

Abstract: Rotating coalescer crankcase ventilation (CV) systems are described. The described CV systems utilize a contact seal to seal a gap between a static side of a housing and a rotating coalescer inlet. The rotating coalescer may be driven mechanically, electrically, hydraulically, or the like. The contact seal can be formed via a soft solid or a liquid film created by oil. Accordingly, the contact seal is a hydrodynamic soft seal. The contact seal prevents the blowby gases from bypassing the filter element of the rotating coalescer. At the same time, the contact seal may be broken during positive blowby gas recirculation circumstances because the contact seal is a hydrodynamic soft seal.

Abstract: Various rotating coalescer elements are described. The rotating coalescer elements include various arrangements of stacked separator discs or cones. In some arrangements, the described rotating coalescer elements include a combination of stacked separator discs or cones and filter media. In some arrangements, the stacked separator discs are designed to provide the largest possible amount of radial-projected separation surface area in a given rotating cylindrical volume, where flow to be cleaned is passing radially (outwardly or inwardly) through the rotating coalescer element. In some arrangements, this is achieved by stacking non-conical separating plates containing various area-maximizing features (e.g., spiral ribs, axial cylinders, spiral grooves, or spiral “V” shapes).

Abstract: Referring to the figures generally, rotating filter cartridges (e.g., a rotating coalescers) for a rotating filtration system (e.g., rotating coalescer crankcase ventilation systems) are described. The described filter cartridges use mechanically created seals to seal the filter media to the endcaps of the filter cartridges. Accordingly, the described filter cartridges eliminate the need to use a potting or embedding material during manufacturing of the filter cartridge, thereby eliminating the costs and potential manufacturing defects associated with the potting or embedding material and process.

Abstract: A spin-on filter that eliminates the use of a nut plate and reduces the number of separate components. Instead, the spin-on filter utilizes the end plate of the filtercartridge to perform a number of functions, including closing the open end of the filter shell, sealing between the dirty and clean fluid sides, sealing between the filter and the mounting head to prevent leakage outside the filter to environment, attaching the filter cartridge to the shell, and sealing the end of the filter media.

Abstract: A rotating separator includes a filter housing extending axially along a longitudinal axis and a filter element positioned within the filter housing. The filter element includes a first endplate and a second endplate operatively coupled to the first endplate, a first element core and a second element core positioned between the first endplate and the second endplate and configured to filter a contaminate from a fluid. An interior cavity is defined between the first endplate, the second endplate, the first element core, and the second element core. Fluid flowing through the filter element enters the interior cavity and is split between and flows in parallel through the first element core and the second element core.

Abstract: A rotating crankcase ventilation filter element comprises a filter media comprising a plurality of filter media layers. A first end cap is positioned on a filter media first end. The first end cap comprises a first end cap main body, and a first plurality of indenting features positioned on the first end cap main body proximate the filter media first end. The first plurality of indenting features contact and indent corresponding segments of the filter media first end, causing the plurality of filter media layers to interlock at the corresponding segments. The interlocking prevents movement of the plurality of filter media layers relative to each other.
