The Working Principle Of The Impactor
Aug 31, 2017

The working principle of the impactor: when the impact stroke begins, both the piston and the valve are in the extreme position, and the air pressure enters the upper chamber of the cylinder through the radial hole of the valve cover and the valve seat, and pushes the piston to move downward at high speed to impact the drill bit. When the piston to the bushing flower keyway is closed, the lower chamber pressure began to rise, so the piston at the top of the hole from the air distribution lever, so that the upper cavity through the atmosphere, pressure reduction, the end of the work trip. When the piston strikes the tail of the drill, the valve plate is reversed because of the upper and lower pressure difference, and the piston repeats the movement of the stroke.
