摘要： The present invention provides a centrifugal separator (1) for cleaning gas containing contaminants. The centrifugal separator is comprising a stationary casing (2), enclosing a separation space (3) through which a gas flow is permitted, a gas inlet (20) extending through the stationary casing (2) and permitting supply of the gas to be cleaned, a rotating member (7) comprising a plurality of separation members (9) arranged in said separation space (3) and being arranged to rotate around an axis (X) of rotation. The separator (1) further comprises a gas outlet tube (28) arranged through the stationary casing (2) and configured to permit discharge of cleaned gas out from the stationary casing (2), a drainage outlet (29) arranged in the stationary casing (2) and configured to permit discharge of liquid contaminants that have been separated from the gas out from the stationary casing and a drive member (22) for rotating the rotating member (7). The centrifugal separator further comprises a stationary insert (30) arranged in the stationary casing (2) and configured for segregating cleaned gas and separated contaminants prior to the cleaned gas and separated contaminants exiting said stationary casing (2), and wherein said gas outlet tube (28) and said stationary insert (30) is formed as a single unit (50).

摘要： The disclosure concerns a crankcase gas separator (2) comprising a separator housing (4) delimiting at least part of a separation space (6) and forming at least part of a liquid phase receiving circumferential inner wall surface (12), a wall member (8) forming at least part of a gas passage (14), and a gas pressure regulating valve (10) comprising at least part of the gas passage (14). The separator (2) comprises a separate tube member (34) extending from a position (36) radially inside the inner wall surface (12) into the gas passage (14). A liquid tight seal between the separate tube member (34) and the wall member (8) is formed by a joint (38) arranged radially outside the inner wall surface (12).
