Abstract
An inflow assembly for use in a subterranean well, which inflow assembly is arranged to prevent one or more fractions of the produced medium from entering the production tubing, comprises at least one chamber containing within it at least three floating/sinking elements, the chamber having an inlet/opening facing in the inflow direction into the chamber, and having an outlet that is open to flow directly from the inlet/opening without being blocked by the floating/sinking element when a desired medium is produced, where the middle one of the elements is arranged to block the outlet aperture from the chamber when undesired medium is produced, whilst the two other elements have the task of forming a movable floor and a movable ceiling in the chamber.
