Abstract

The pneumatic impact device (1) has an impact piston (5), displaced axially within a housing (2), in the direction of its upper wall (3), against the force of a return spring (8), via compressed air, with rapid venting of the chamber (7) below the impact piston upon reaching a given stroke via a control element (4) within the impact piston, which opens an air channel (16). the latter is closed by movement of the impact piston into its lower position.
