A centrifugal separator for cleaning crankcase gas, containing oil, from an internal combustion engine, includes a stationary casing defining a separation space and including a first end portion, an opposite second end portion and an inner wall surface facing the separation space. The separator also includes an inlet channel for the gas to be cleaned, a gas outlet channel for the cleaned gas and an oil outlet for the separated the oil. A centrifuge rotor is provided in the separation space and includes a spindle and a plurality of separation discs carried by the spindle. The centrifuge rotor is rotated to create a rotating gas volume. An oil supply device supplies such a quantity of oil to the separation space that a flowing oil film is created on the inner wall surface during operation of the centrifugal separator. |

1. A centrifugal separator for cleaning crankcase gas, containing oil, from an internal combustion engine, said centrifugal separator comprising:
a stationary casing defining a separation space and comprising a first end portion and an opposite second end portion, wherein the stationary casing has an inner wall surface facing the separation space; an inlet channel, extending to the separation space and forming an inlet for the gas to be cleaned; a centrifuge rotor, said centrifuge rotor being provided in the separation space and extending from the first end portion to the second end portion, wherein the centrifuge rotor comprises a spindle and a plurality of separation discs carried by the spindle; a drive member provided to rotate the centrifuge rotor in a direction of rotation about an axis of rotation to create a rotating gas volume, whereby oil is separated from the gas by means of centrifugal forces; a gas outlet channel for discharging the cleaned gas from the separation space; an oil outlet for discharging the oil from the separation space; and an oil supply device, wherein the oil supply device is configured to supply a sufficient quantity of oil to the separation space, so that a flowing oil film is created on the inner wall surface during operation of the centrifugal separator. |
