摘要： The invention refers to a centrifugal separator for cleaning of a gas containing liquid impurities. A stationary casing (1) encloses a separation space (2) and has an inner wall surface (3) facing the separation space. An inlet (9) is provided for the gas to be cleaned. A rotating member (4) is provided in the separation space downstream the inlet and arranged to rotate in a direction (r) of rotation around an axis (x) of rotation. The rotating member brings the gas to rota- tion in the direction (r) of rotation for separation, by means of centrifugal forces, of liquid impurities from the gas. A gas outlet (10) is provided downstream the rotating member for discharge of the cleaned gas. A first liquid outlet (11) is provided upstream the gas outlet and downstream the rotating member for discharge of sepa- rated liquid impurities and comprises at least one outlet hole. A surrounding ring groove (19) extends outwardly from the inner wall surface in the stationary casing and has a surrounding bottom surface (20), wherein the outlet hole extends outwardly from the bottom surface.

摘要： This document describes a device for cleaning of crankcase gases from a combustion engine (1 ), and a combustion engine having such a device. An inlet conduit (20) is connected to a crankcase (3) of the combustion engine. A centrifugal separator (10) receives a flow of crankcase gases from the crankcase via the inlet conduit and comprises a rotable centrifuge rotor (11 ) for centrifuging the crankcase gases. A drive device (13) drives the centrifuge rotor. An outlet conduit (21 ) discharges cleaned crankcase gases from the centrifugal separator. The rotary speed of the drive device, and thus the rotary speed of the centrifuge rotor, is controllable depending on the gas pressure in the crankcase. An export conduit (25) may be connected to the inlet conduit and adapted to enable discharge of a flow of crankcase gases from the crankcase by-passing the centrifugal separator depending on the gas pressure in the crankcase. An import conduit (30) may be connected to the inlet conduit and adapted to enable feeding of a flow of air from the surroundings to the crankcase depending on the gas pressure in the crankcase.
摘要翻译：本文件描述了用于从内燃机（1）清洁曲轴箱气体的装置和具有这种装置的内燃机。入口管道（20）连接到内燃机的曲轴箱（3）。离心分离器（10）经由入口导管接收来自曲轴箱的曲轴箱气体流，并且包括用于离心曲轴箱气体的可旋转的离心机转子（11）。驱动装置（13）驱动离心机转子。出口导管（21）从离心分离器排出清洁的曲轴箱气体。驱动装置的旋转速度以及离心机转子的转速可根据曲轴箱内的气体压力来控制。输出管道（25）可以连接到入口导管，并且适于能够根据曲轴箱内的气体压力排出来自曲轴箱的曲轴箱气体的流动，绕过离心分离器。进口导管（30）可以连接到入口导管，并适于根据曲轴箱内的气体压力使空气从周围流入曲轴箱。
