Abstract: A crankcase ventilation device includes a housing and a flow directing member. The housing defines an inlet, an outlet and an internal volume. The inlet is configured to receive blow-by from an engine. The flow directing member is coupled to the housing and extends into the internal volume. The flow directing member includes a plurality of sidewalls, at least two of the plurality of sidewalls defining a window that fluidly couples the inlet to the internal volume. A filter media may be coupled to the flow directing member.

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: 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.

Abstract: A rotating crankcase ventilation system comprises a housing comprising an inlet and an outlet, a motor comprising a stator and a rotor, and a shaft. A first end of the shaft is coupled to the rotor and configured to rotate in response to rotation of the rotor. A filter element is coupled to the shaft. A sensor is configured to measure at least one operating parameter of the rotating crankcase ventilation system. A controller is operatively coupled to the sensor and the motor, the controller configured to receive the at least one operating parameter and selectively adjust operation of the motor to adjust rotation of the rotor, and thereby, the filter element based on the at least one operating parameter.
