A lubrication system comprises a chamber adapted to contain a lubricant and a duct to convey lubricant from the chamber to the apparatus to be lubricated. A pipe is adapted to introduce air into the lubricant flowing through the duct so that for a given flow rate through the duct the rate at which lubricant is withdrawn from the chamber is reduced when compared with the rate when no air is introduced into the lubricant flow.

A tank suitable for holding a lubricant and adapted to comprise a portion of a lubrication system comprising first and second baffles respectively adapted to divide the interior of said tank into first, second and third series interconnected chambers, each adapted to contain said lubricant, an inlet adapted to supply a mixture of a gas and a lubricant to said first chamber, outlet duct means adapted to withdraw lubricant from said third chamber and venting means having an outlet through which said gas present in said first chamber is vented, said baffles being so adapted and arranged than when said tank is in its normal spacial disposition, lubricant supplied in operation to said first chamber flows into said third chamber via said second chamber, and if said tank is subsequently inverted with respect to said normal spacial disposition, any flow of lubricant from said third chamber to said second chamber is prevented or is of a sufficiently low level that an adequate quantity of lubricant is retained within said third chamber to provide a continuity of lubricant flow through said outlet duct means for a finite time period, and insufficient lubricant flows from said second chamber into said third chamber to obstruct said venting means, said outlet duct means being provided with means adapted to introduce a gas into lubricant passing therethrough when said tank is inverted with respect to said normal spacial disposition.
