ABSTRACT:
A grease gun has a grease container with a low pressure piston, and a high ressure part with a high pressure piston in a passage. The high pressure part is located on a cap screwed to the grease container. The high pressure part is connected through a hole with the interior of the grease container and has an outlet nozzle extending perpendicularly to the high pressure piston and having a passage and a valve. A hand lever is journalled to the high pressure piston and mounted on a pivoting link joining it to the high pressure part. The high pressure part and the outlet nozzle are made as an integral one piece component bend of round steel stock pressed and bent into an L-shape into which the necessary passages are formed after the bending and pressing. These passages may be formed also by pressing, or drilling, or the like.
