8-1. Striking Operation
The rotation of the armature is transferred to the crank shaft and connecting rod, which in turn cause the piston to
reciprocate inside the cylinder. As the piston reciprocates, the changing air pressure inside the air chamber
between the piston and the striker causes the striker to continuously strike against the end of the second hammer.
At the same time, the air-cushion effect within the air chamber absorbs the impact of the striker. Should the air
escape from the air chamber, the air-cushion effect would cease, and the impact energy would not be absorbed.
Accordingly, the O-rings mounted on the striker and the piston play an extremely important role in sealing the air
within the air chamber.
