The six planetary pinions rotate in constant mesh with the internal gears.
One drive shaft is splined to the central gear and the other to the planetary gear.
Each planetary pinion gear meshes with both the central gear and the internal gear.
The internal gear is fixed to the planetary gear.

Lubricates the cylinder wall by releasing oil from its hole
Keeps the cylinder wall lubricated by holding oil in its channel
Prevents engine oil from going into the combustion chamber and returns excess lubricating oil off the cylinder wall through the return holes in the piston to the oil pan
Maintains a seal and prevents escape of burned gases and oil leakage
