Working Principle
1.During the down cycle or power stroke the piston reseals the
bottom chamber on the piston bearing bush thus stopping the exhaust
air and creating a chamber of high pressure air below the piston
which forces the piston back up the hammer.
2. Lifting the hammer of the bottom of the hole allows the
percussion bit to slide down the drive sub also allowing the piston
to slide down the hammer and rest on the piston bearing bush. The
piston strike face and the strike face of the percussion bit can
now not come into contact thus allowing the free flow of high
pressure air directly through the hammer without the hammer
cycling.
