Abstract

An inlet device to a separator including a generally tubular outer wall and a generally tubular inner wall. The walls define at least a part of a first annular path between them. An inlet opening provides for the passage of a fluid through the outer wall into the first annular path. At least one communication channel provides for the passage of a fluid from the first annular path into the second annular path. At least one movable closing element provides for at least partial closure of the fluid passage from the first path into the second path. The communication channel(s) is/are arranged to extend along the outside of the inner wall downwards from the first path into the second path, wherein the second path is arranged below the first path.
