The device is described below with the aid of the appended drawings, it having to be understood that the drawings are diagrammatic drawings and do not limit possible embodiments which are compatible with the concept of the invention. The "PNEUMATIC LUBRICATOR" consists of one or more cylindrical tanks 4 and of other cylindrical tanks 8 of smaller diameter, and one or more plungers 7 operate inside the latter. One or more plungers 5 operate in the cylinder or cylinders 4. This cylinder or these cylinders 5 and the plunger or plungers 7 are connected by one or more shafts 6. The tank or tanks 4 receives or receive air pressure via one or more tubes 1 which has or have, intercalated, one or more cut-off tap valves 2 which, when closed, makes or make it possible to maintain the air pressure in the tank or tanks 4. The tank or tanks 4 is or are protected by one or more safety valves 3. Upon entering via the tube or tubes 1 to the tank or tanks 4, the air actuates the plunger or plungers 5, making the latter compress the plunger or plungers 7 via the shaft or shafts 6. The lubricant which is inside the cylinder or cylinders 8 is compressed through the action of the plunger or plungers 7 which, via a hole or holes in the cover or covers 9, will let in overpressure in the tube or tubes 10 in which there is or are, at the end, one or more lubrication guns 11. In order to lubricate, it suffices to operate the gun or guns 11 where the lubricant is under pressure. The "pneumatic lubricator" is further equipped with one or more handle or handles 12 to facilitate its transportation. <IMAGE>
