Abstract: A gas-liquid separator comprises a housing comprising a first inlet structured to receive a blowby gas stream, the blowby gas stream having a first flow velocity, and a second inlet structured to a communicate a compressed gas into the housing, at least a portion of the second inlet disposed within the first inlet. An elastomeric nozzle is coupled to the first inlet and positioned around the second inlet, the elastomeric nozzle structured to combine the blowby gas stream with the compressed gas such that the compressed gas causes the blowby gas stream to flow at a second flow velocity that is greater than the first flow velocity. An impaction plate is disposed downstream of the elastomeric nozzle such that the blowby gas stream impacts the impaction plate and separates liquid and aerosol contained in the blowby gas stream.

Abstract: A crankcase ventilation element is provided. The element includes a plate including a first port. The first port extends from the plate in a first direction. The element includes a housing coupled with the plate. The housing defines an axial centerline. The housing includes a second port extending from the housing in a second direction opposite the first direction. The housing includes a flange extending around a perimeter of the housing. The flange includes a sealing surface. The element includes a filter media disposed between the plate and the housing. The first port and the second port intersect the axial centerline. The first port is axially offset from the second port. The first port is laterally offset from the second port.

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: Referring to the figures generally, a rotating filter cartridge includes a first endcap, a second endcap, and a filter media. The filter media is positioned between the first endcap and the second endcap. The filter media creates a mechanical seal between at least one of the first endcap or the second endcap during rotation of the rotating filter cartridge without the use of a potting material. In at least one embodiment, the rotating filter cartridge further includes a body secured to the first endcap and the second endcap. At least one of the first endcap or the second endcap, and the body, may form a pocket that radially pinches the filter media to form the mechanical seal.

Abstract: A filter media holder for securing a filter media within a filter housing comprises a first grill plate having a plurality of first apertures defined therethrough, and a second grill plate having a plurality of second apertures defined therethrough. In a first configuration, the second grill plate is spaced apart from the first grill plate to allow a filter media to be disposed on the first grill plate or the second grill plate, and in a second configuration, the second grill plate is disposed proximate to the first grill plate such that the filter media is secured between the first grill plate and the second grill plate.

Abstract: A filter that is retained in a shell housing by the use of a snap connection. The filter includes an endplate having snap features that interact with a groove in an inner portion of the shell housing. The groove may extend 360 degrees around an inner circumference of the shell housing. Accordingly, when the shell is unthreaded from the head service (e.g., during a filter replacement service), the shell only needs to be displaced the length of the inner radial seal interface between the shell and the head, not the entire length of the filter media thereby minimizing the stroke length needed to service the filter assembly.

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.

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: 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.
