8-1. Striking Operation
The rotation of the armature is transferred to the crank shaft and the 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 air within the air chamber.
