<p>An apparatus for continually skimming off a top layer (2) of a body of liquid (3) includes a self-adjusting container (4) for collecting said top layer, said container being adapted to seek an effective balanced position dependent on the liquid level for collecting the top layer, and a discharge conduit (7) for discharging the top layer collected by said container, wherein said container is tiltably coupled to said discharge conduit. A feeding inlet (5) is provided through which the top layer is collected. A bearing made of friction reducing material is provided between the container wall and discharge conduit, with a clearance to minimize frictional contact and to allow leakage flow from the body of liquid into the container.</p> |
