  • Patent number: 12241391
    Abstract: A crankcase gas separator includes a separator housing delimiting at least part of a separation space and forming at least part of a liquid phase receiving circumferential inner wall surface, a wall member forming at least part of a gas passage, and a gas pressure regulating valve including at least part of the gas passage. The separator includes a separate tube member extending from a position radially inside the inner wall surface into the gas passage. A liquid tight seal between the separate tube member and the wall member is formed by a joint arranged radially outside the inner wall surface.
    Type: Grant

  • 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.
