  • Patent number: 10967388
    Abstract: A centrifugal separator for separating a liquid phase from crankcase gases of an internal combustion engine includes a separation chamber, a rotor shaft, a rotor inside the separation chamber, an inlet for crankcase gases, a gas outlet, and a liquid outlet for separated liquid phase. The centrifugal separator also includes a liquid outlet chamber, a check valve, and a rotating member. The liquid outlet chamber forms an individual chamber and is arranged in fluid communication with the separation chamber via a liquid passage. The rotating member is connected to the rotor shaft and is arranged inside the liquid outlet chamber. The liquid outlet forms an outlet of the liquid outlet chamber. The check valve is arranged in the liquid outlet.

  • Patent number: 8747503
    Abstract: The present invention relates to a separator and more specifically, but not exclusively, to a centrifugal separator for the cleaning of a gaseous fluid. A centrifugal separator is provided as comprising a housing defining an inner space, and a rotor assembly for imparting a rotary motion onto a mixture of substances to be separated. The rotor assembly is located in said inner space and is rotatable about an axis relative to the housing. The rotor assembly comprises an inlet for receiving said mixture of substances, an outlet from which said substances are ejected from the rotor assembly during use, and a flow path for providing fluid communication between the inlet and outlet, wherein the outlet is positioned more radially outward from said axis than the inlet.
