Abstract
An arrangement in a circulation lubrication system includes a lubricating oil tank, pressure pipe lines for supplying oil to parts that are to be lubricated, return pipe lines for returning the oil from the parts that are to be lubricated to the oil tank, and a mechanism for pumping oil into the pressure pipe lines and maintaining a desired state of lubrication. The lubricating oil tank has a rotationally symmetric structure; and a return duct, positioned at the center axis of the rotationally symmetric structure, is configured to extend below the surface of the oil in the lubricating oil tank. A return flow through the return duct passes through a dividing element to a mechanism configured to separate impurities from the oil.
