  • Patent number: 8758469
    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.

  • Patent number: 7875098
    Abstract: The invention refers to a centrifugal separator comprising a stationary casing defining an inner space, a spindle and a rotating member, which is attached to the spindle and arranged to rotate around an axis of rotation with a rotary speed. The rotating member comprises a number of separating discs which are provided in the inner space. A drive member drives the spindle and the rotating member with said rotary speed. A sensor device senses the rotation of the rotating member in relation to the casing. The sensor device comprises at least one transmitter element which is provided in the inner space on the rotating member and a receiver element which is provided at the casing and arranged to sense the transmitter element. The receiver element is provided on the casing outside the inner space.

  • Patent number: 7476266
    Abstract: In an apparatus for cleaning of gases a centrifugal rotor is supported by two bearings, in which it is rotatable about a rotational axis. The two bearings are lubricated by means of an oil mist, which is generated in a space, when oil is sprayed against a turbine wheel supported by the rotor. Whereas the bearing, which is situated nearest said space, is lubricated by oil mist present in the space, the second bearing is lubricated by oil mist being conducted to it through a central channel in the centrifugal rotor.

  • Patent number: 7465341
    Abstract: In an apparatus for cleaning of a gas a centrifugal rotor is rotatable in a separation chamber about a vertical rotational axis (R). The centrifugal rotor is rotatable by means of a turbine wheel arranged in a drive chamber situated below the separation chamber. The centrifugal rotor and the turbine wheel are connected with each other by means of a shaft. The separation chamber and the drive chamber are separated from each other by two partitions, through which the shaft extends and which between themselves form a drainage chamber. A nozzle is arranged to spray a liquid against the turbine wheel in the drive chamber for rotation thereof and of the centrifugal rotor. The drainage chamber has an outlet for draining of liquid having entered the drainage chamber from the drive chamber, so that liquid shall not be able to flow from the drive chamber to the separation chamber.

  • Patent number: 7338546
    Abstract: In a centrifugal separator for cleaning gases generated by an internal combustion engine a housing defines an interior separation chamber. A centrifugal rotor is coupled for rotation to the housing and extends into the separation chamber. A drainage chamber is positioned adjacent the separation chamber and is delimited therefrom by a partition wall. A flow path is provided through which oil, separated from gases generated by the internal combustion engine and collecting on the partition wall, can travel from the separation chamber to the drainage chamber. A pump wheel is coupled to a shaft portion defined by the rotor and extends radially outwardly therefrom. During operation the oil, upon exiting the separation chamber, contacts the pump wheel. Centrifugal forces generated due to the rotation of the pump wheel cause the oil to be thrown into the drainage chamber. The pump wheel also minimizes the potential for oil resident in the drainage chamber to re-enter the separation chamber.
