When gear as shown in the direction of rotation, the right side of the oil absorption cavity teeth gradually separated, the workspace volume increases gradually, the formation of partial vacuum, so the oil in the tank to the outside world under the action of atmospheric pressure and the suction tubing into the oil absorption cavity, into the oil in a sealed between tooth workspace with gears rotate to the left side of the oil cavity pressure, because the left side of the tooth meshing, gathering volume of workspace is reduced, so the teeth taken out of the oil, the oil chamber to the pressure piping.
