Abstract: Various example embodiments relate to rotating coalescers. One embodiment includes a housing comprising a first housing section having a blowby gas inlet structured to receive crankcase blowby gases from a crankcase. The housing further comprises an oil outlet. The rotating coalescer includes an endcap and filter media. The filter media is arranged in a cylindrical shape and is coupled to and positioned between the first housing section and endcap. The filter media is structured to filter the crankcase blowby gases passing through the filter media by coalescing and separating oils and aerosols contained in the crankcase blowby gases. The rotating coalescer includes a hollow shaft extending through the housing and positioned radially inside of the filter media. The hollow shaft forms a blowby gas outlet structured to route filtered crankcase blowby gases out of the housing. The rotating coalescer further includes a drive mechanism operatively coupled to the hollow shaft.

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: Radial seal filter assemblies and filter cartridges are described. According to various embodiments, a filter includes a housing that extends along an axis between first and second axial ends. A primary filter element is disposed in the housing and axially extends between first and second axial ends that respectively are adjacent the first and second axial ends of the housing, the primary filter element has a hollow interior and a first axial length. A secondary filter element is disposed in the hollow interior of the primary filter element, the secondary filter element having a second axial length, the second axial length being longer than the first axial length of the primary filter element. The filter further includes an end cap disposed on the second axial end of the primary filter element.

Abstract: Assembly to be used to filter a fluid, containing a housing (29) which comprises a housing base (50) and a housing upper part (30) connected removably to the housing base (50). An axial shaft (34, 35) extends at least partially through the filter element (32, 33) when the filter element (32, 33) is contained inside the housing (29). A lower bearing (44) is arranged between the axial shaft (34, 35) and the housing base (50) and underneath the filter element (32, 33) when a filter element (32, 33) is contained inside the housing (29). The housing (29) is able to contain a filter element (32, 33) within it and the filter element (32, 33) fits onto the axial shaft (34, 35) in such a way that the axial shaft (34, 35) is rotationally coupled to the filter element (32, 33). The filter assembly (20, 120) has no bearing above the filter element (32, 33).

Abstract: The present invention relates to a filtration assembly for filtering a fluid flowing in particular in a motor or a hydraulic equipment, comprising: —a filter body having a tank and a cover, the filter body being intended to house a filter cartridge, —at least one locking system for the filter body, being movable between a locking position and an unlocking position, wherein said filtration assembly has means for holding the locking system (5) in the unlocking position.

Abstract: A pleated filter media comprises a plurality of pleats comprised of pleat segments extending in an axial direction between first and second axial ends and extending in a transverse direction that is perpendicular to the axial direction between first and second sets of pleat tips at least partially defined by first and second sets of bend lines. Axial flow channels are defined between the pleat segments in the lateral direction and the plurality of pleats has a width in the transverse direction that varies along the axial direction.
