摘要： Filter media having a design embossed into the media are described. In some arrangements, the filter media is pleated filter media. In other arrangements, the filter media includes a plurality of channels, such as tetrahedron channels. The filter media includes a pattern of interrupted straight or angled embossments that help maintain separation between adjacent layers of the filter media. The embossments allow for two adjacent media layers (e.g., mating surfaces of the filter media) to remain separated, thereby increasing dust holding capacity and lowering pressure drop over similarly configured filter media not having the embossments.
摘要翻译：描述具有压印到媒体中的设计的过滤器媒体。在一些布置中，过滤介质是打褶的过滤介质。在其它布置中，过滤介质包括多个通道，诸如四面体通道。过滤介质包括有助于维持过滤介质的相邻层之间分离的中断的直的或成角度的凸起的图案。浮雕允许两个相邻介质层（例如，过滤介质的配合表面）保持分离，由此增加了容尘量并降低了类似构造的不具有凸起的过滤介质上的压降。

摘要： 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.

摘要： 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.

摘要： A crankcase ventilation system comprises a housing defining an internal volume structured to receive a. rotating air/oil separator element. The housing has a housing inlet structured to receive a fluid and a housing outlet defined tangentiaily in a sidewall of the housing which is structured to allow the fluid to exit the housing. An outlet conduit is fluidly coupled to housing outlet. The outlet conduit comprises an outlet conduit first portion axiai ly aligned with the housing outlet, and an outlet conduit second portion positioned downstream of the outlet, conduit first, portion. A swirl breaking structure is positioned in at least one of an outlet conduit inlet and the outlet conduit second portion. The swirl breaking structure is configured to disrupt swirling flow of the fluid into the outlet conduit so as to reduce a pressure drop experienced by the fluid as the fluid flows from the housing into the outlet conduit.
