    Abstract: A rotating separator including a filter element extending axially along a longitudinal axis and including a first endplate, a second endplate, and a separating element. The first endplate includes a center tube. The second endplate is coupled to the first endplate and includes a central aperture having a perimeter and receiving the center tube. The filter element also includes an axially extending slot and an axially extending protrusion positioned on one of the first endplate and the second endplate and configured to engage with each other. The first and second endplates form an interior cavity when coupled together. The rotating separator includes a filter structure positioned within the interior cavity.

    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 translation: 各种示例实施例涉及旋转聚结器。 一个实施例包括壳体，该壳体包括第一壳体部分，该第一壳体部分具有构造成接收来自曲轴箱的曲轴箱窜气的窜漏气体入口。 该壳体还包括一个油出口。 旋转式聚结器包括一个端盖和过滤介质。 过滤介质布置成圆柱形并且联接到第一壳体部分和端盖之间并且定位在第一壳体部分和端盖之间。 过滤介质构造成通过聚结和分离曲轴箱窜漏气体中含有的油和气溶胶来过滤通过过滤介质的曲轴箱窜气。 旋转聚结器包括延伸穿过壳体并定位在过滤介质的径向内侧的中空轴。 中空轴形成窜漏气体出口，其构造成将经过滤的曲轴箱窜气排出壳体。 旋转聚结器还包括可操作地连接到中空轴的驱动机构。

    Abstract: An air-liquid separation assembly for separating air and liquid from an air-liquid mixture comprises a housing through which fluid flows, a main separator positioned within the housing, and a sub-separator. The sub-separator is positioned within the housing before or after the main separator and defines a plurality of slots. Each of the plurality of slots is positioned either between adjacent baffles of the sub-separator or between a baffle of the sub-separator and a portion of the housing. The plurality of slots are positioned next to each other in a direction substantially perpendicular to the direction of fluid flow through the housing. The plurality of slots comprises a first subset of slots and a second subset of slots. The second subset of slots extends at a different angle than the first subset of slots such that fluid flows through the first subset of slots and the second subset of slots at different angles.

    Abstract: A gas-liquid separator includes a housing. The housing includes an inlet structured to receive a blowby gas stream from a crankcase. a cleaned air outlet, and a liquid outlet. A cover is disposed downstream from the inlet and upstream from the liquid outlet. The cover includes a baffle disposed over the blowby gas stream flow path from the inlet. The blowby gas stream impacts the baffle and separates liquid and aerosol contained in the blowby gas stream. A flange extends substantially axially downward from a side of the baffle. The flange is tapered substantially axially downward forming an inner surface. The inner surface is structured to route the separated liquid toward the liquid outlet. The inner surface biases separated liquid away from shedding toward the cleaned air outlet.
