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 water drain valve system structured to drain water from a fuel-water separator. The system includes a collection vessel structured to temporarily store water, a liquid level sensor structured to monitor a level of the temporarily stored water, a drainage port extending radially from the collection vessel and having a port inlet and a port outlet, and a valve assembly. The port inlet receives water to be drained from the collection vessel, the water flowing through the drainage port and exiting through the port outlet. The valve assembly is movable between a closed position in which the port outlet is closed, and an open position, in which the port outlet is open, to selectively allow water to be drained from the collection vessel. The valve assembly includes a solenoid coupled to a seal member, the seal member closing the port outlet in the closed position of the valve assembly.
