Claim Text:
1. An inlet device for a centrifugal separator for directing a liquid mixture that is to be separated from an inlet pipe to a separation chamber, wherein said inlet device is rotatable around a central rotational axis, the inlet device comprising: a body; a central conical receiving structure at a center of the body, the central conical receiving structure comprising an outer surface, an outer edge and a central receiving zone for receiving said liquid mixture from the inlet pipe and wherein said central receiving zone surrounds an apex of said central conical receiving structure; and at least one inlet channel for directing said liquid mixture from said central receiving zone to said separation chamber, wherein said at least one inlet channel is formed by two opposed sidewalls, the two sidewalls having a first section extending from a periphery of the central conical receiving structure and spiralling outwardly along the outer surface of said central conical receiving structure and a second section extending in a straight radial direction from the outer edge of the central conical receiving structure to an inlet channel outlet, wherein said at least one inlet channel extends from the central receiving zone in a direction that forms an angle α with a tangent of a periphery of the central receiving zone and wherein the angle α is less than 90°, and wherein said inlet channel outlet is configured to be in contact with the separation chamber of the centrifugal separator.
