摘要： Upon cleaning of crankcase gas generated during operation of an internal combustion engine (31; 41) in its crankcase, a centrifugal separator (34; 50) is used, which includes a rotor arranged for rotation by means of a driving motor (9; 49) and arranged by its rotation to suck crankcase gas from the crankcase through a conduit (51) to the centrifugal separator. During operation of the combustion engine (31; 41) a parameter, e.g. a measurement of the load on the combustion engine (31; 41), is sensed, the magnitude of said parameter being related to the amount of crankcase gas generated per unit of time in the crankcase. Depending upon a sensed change of the sensed parameter the rotational speed of the rotor of the centrifugal separator (34; 50) is changed in a way such that the gas pressure in the crankcase is maintained at a predetermined value, or within a predetermined pressure interval, during the operation of the combustion engine (31; 41).

摘要： A method and a device for separation of a fluid in the liquid state comprising two liquids that are not mutually miscible, with different densities, wherein a first liquid is to be cleansed from a second liquid, whereby the fluid in the liquid state is conducted through a rotor where centrifugal separation of the second liquid from the first liquid takes place, and is then conducted into a tank (8), with the proportion of the second liquid being reduced to less than 5%, and by conducting the fluid, after centrifugal separation, through a restriction (9), whereby the pressure of the fluid in the liquid state is reduced, which causes portions of the fluid in the liquid state to evaporate so that further portions of the second liquid escape in the form of a gas which is conducted away, thereby further reducing the proportion of the second liquid in the outgoing fluid in the liquid state.
