Abstract
Percussion apparatus including a fixed outer cylinder, an energy transmission mechanism supported by said external cylinder, said energy transmission mechanism being of a type capable of transforming the rotary movement into a reciprocating movement, an internal cylinder that can slide in the interior of said external cylinder, said internal cylinder being connected to said energy transmission mechanism that is intended to be connected to an external primary motor; a plunger that can slide into said inner cylinder, an upper sealing cap arranged on top of said inner cylinder, a lower sealing cap arranged on the bottom of said inner cylinder, a central hole formed in said lower sealing cap, an upper pressure chamber being defined by the inner circumferential surface of the wall of said inner cylinder, the inner surface of the wall of said upper sealing cap and the extreme upper surface of said free piston, a lower pressure chamber being defined by the inner circumferential surface of the wall of said inner cylinder, the inner surface of the wall of said lower seal cap and the lower end surface of said free piston, said upper pressure chamber having a volume considerably higher than that of said lower pressure chamber, a hammer which is an integral part or which is attached to said free piston, said hammer extending outwards through said central hole of said lower sealing cover in airtight position relative to it, and an impact tool attached to said hammer or located with respect to said hammer so that said hammer can hit it.
