<p>An arrangement in connection with a circulation lubrication system, comprising an intermediate tank, inlet channel means (2) for feeding a lubricant into the intermediate tank (1), and outlet channel means (3) for removing the lubricant, discharge means (5) for emptying the intermediate tank, and measuring means (6, 7) arranged to start the discharge means (5) when the level of the lubricant rises to an upper limit and to stop the discharge means (5) when the level of the lubricant falls to a lower limit. The discharge means (5) comprise a pneumatic valve (8), which is opened, when the level of the lubricant is at the upper limit, and to let pressurized air flow into the intermediate tank (1), whereby the pressurized air pushes the lubricant out of the intermediate tank (1) through the outlet channel means (3), and prevents the flow of pressurized air into the intermediate tank (1) when the level of the lubricant falls to the lower limit. A counter valve (9) is arranged to prevent the flow of the lubricant out of the intermediate tank (1) into the inlet channel means (2).</p> |
