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.

Rotating separator with single assembly orientation and integrated counterbalance

A filter assembly includes a filter housing having a longitudinal axis, the filter housing divided into a first filter chamber and a second filter chamber, a first element bottom endplate, a second element top endplate, an intermediate endplate positioned along the longitudinal axis between the second element top endplate and the first element bottom endplate, a first filter element housed within the first filter chamber and comprising first filter media positioned between the first element bottom endplate and the intermediate endplate, and a second filter element housed within the second filter chamber and comprising second filter media positioned between the second element top endplate and the intermediate endplate.

Integrated module with stage one and stage two filters combined in single housing

The application relates to a separation assembly with multiple separators and a single jet pump assembly. A separation assembly comprises a first crankcase ventilation separator comprises a first drain outlet, a second crankcase ventilation separator that comprises a second drain outlet, and a jet pump assembly. The jet pump assembly comprises a first drain inlet fluidly connected to the first drain outlet of the first crankcase ventilation separator and a second drain inlet fluidly connected to the second drain outlet of the second crankcase ventilation separator. The jet pump assembly provides suction pressure to both the first drain outlet of the first crankcase ventilation separator and the second drain outlet of the second crankcase ventilation separator.

A filter element comprising a filter media having a first end and a first endcap coupled to the first end of the filter media. The first end-cap includes a flexible first endcap body having a first endcap rigid reinforcing member internally embedded therein. The first endcap rigid reinforcing member may comprise a wire mesh screen and the filter media may comprise a pleated filter media. The filter element may further comprise a second end-cap coupled to a second end of the filter media. The second endcap may include a flexible second endcap body having a second endcap rigid reinforcing member internally embedded therein.

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.

Various embodiments provide for a filter assembly. The filter assembly includes a filter housing, a filter element, and a cover. The cover includes a first cover end and a second cover end disposed axially away from the first cover end. A second coupling member is adjacent to the second cover end. The second coupling member is configured to engage a first coupling member to couple the cover and the filter housing. A biasing member is coupled to the first cover end. An interface plate is configured to press against a first endplate of the filter element to secure the engagement of a first engagement portion of a filter seal member of the filter element and a second engagement portion of a housing seal member of the filter housing.

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.

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.

Oil management structures in crankcase ventilation

A separation assembly comprises a housing and a bearing plate assembly. The housing contains a turbine assembly and a rotor portion and defines a fluid inlet and a fluid outlet. The bearing plate assembly is adjustably attachable to the housing and defines a drive jet that directs fluid from the fluid inlet to the turbine assembly. The bearing plate assembly is mountable to the housing in multiple different orientations such that the relative position of the fluid inlet of the housing and the drive jet of the bearing plate assembly is adjustable.
