    Abstract: An impactor separator comprises a housing having an inlet receiving a gas-liquid stream and an outlet expelling a gas stream. The impactor separator also includes an impaction surface positioned within the housing and configured to separate liquid particles from the gas-liquid stream and a nozzle assembly positioned within the housing. The nozzle assembly includes a nozzle assembly housing portion and a plurality of nozzles extending through the nozzle assembly housing portion. Each of the plurality of nozzles includes a nozzle inlet and a nozzle outlet. The gas-liquid stream enters into the nozzle assembly housing portion, flows into the plurality of nozzles through the nozzle inlet and exits the plurality of nozzles through the nozzle outlet. The plurality of nozzles accelerates the gas-liquid stream toward the impaction surface.

    Abstract: A filter assembly comprises a filter head, a port, a fitting, and a diffuser. The port extends from a portion of the filter head and defines a channel for fluid to flow into or out of the filter head. The fitting first end is attachable to the port and the fitting second end is attachable to a filtration system component. The diffuser is positionable within the channel of the port and comprises an inner surface and an outer surface. The inner surface defines an inner conical hollow region that extends at a nonzero angle between the inner conical hollow region first end and the inner conical hollow region second end such that a first inner diameter of the diffuser at the inner conical hollow region first end is smaller than a second inner diameter of the diffuser at the inner conical hollow region second end.

    Abstract: Various arrangements of a turbine for a rotating coalescer element of a crankcase ventilation system for an internal combustion engine are described. In some arrangements, the turbine is an impulse turbine, which is also known as a pelton turbine or a turgo turbine. The turbine is used to convert hydraulic power from a stream of pressurized fluid to mechanical power that is used to drive the rotating element. The turbine includes a non-wetting surface (e.g., an oleophobic or hydrophobic surface) that repels the pressurized fluid. The non-wetting surface may be achieved through plasma coating, fluoropolymer coating, micro-topography features, and the like. The non-wetting surface increases the power transmission efficiency from the stream of pressurized fluid to the turbine, thereby increasing the rotational speed of the rotating element compared to wettable surfaced turbines, which in turn increases the efficiency of the rotating element.

    Abstract: A filter element for filtering a fluid that comprises a pleated filter media and a support structure. The pleated filter media comprises pleats that define an upstream gap along an upstream surface of the pleated filter media and a downstream gap along a downstream surface of the pleated filter media. The support structure extends along the downstream surface of the pleated filter media and supports the pleats. The support structure is folded into two layers comprising a first layer and a second layer within the downstream gap. The first layer inner surface and the second layer inner surface are positioned adjacent to each other within the downstream gap. The support structure comprises at least one spacer that increases a distance between the first layer outer surface and the second layer outer surface such that the differential pressure drop through portion of the support structure that is within the downstream gap is decreased.

    Abstract: A filter assembly includes a housing having an outer cavity and an inner cavity, and a gasket disposed within the housing. The gasket includes an inner surface, an outer surface, and a vent passage. The gasket forms a first seal with a central tube at the inner surface. The central tube extends into the inner cavity and includes an opening. A filter element is positioned within the housing and includes a filter media configured to filter a fluid and an endcap including an annular tab portion that forms a second seal with the outer surface of the gasket when the filter element is positioned in an operating position within the housing. The vent passage circumvents the first seal and the second seal, allowing air to flow from the inner cavity of the housing to the opening in the central tube.
