Abstract (en)
[origin: EP1340596A1] The pneumatic hammer mechanism for a hammer drill (1) has a pot-shaped flying piston (2), with a header (3) able to move into the pot cavity within a set length. The header, with the flying piston, forms a damping radial gap (X) for the closed gas-tight pot cavity (4), which reverses the motion within the set length.
