摘要：
The invention relates to a boring and/or percussion hammer comprising an electrodynamic linear drive and a pneumatically damped percussion mechanism which is provided with a drive piston (1) driven by the linear drive during the reciprocating movement thereof, an impact piston (3) and a pneumatic spring (7) arranged between the drive and impact pistons. An air-supply device comprises a pumping element (13), which is linearly forth and back movable for generating airflow. The pumping element (13) is connected to the drive piston (1) in such a way that the movement thereof is transmitted to said pumping element (13), thereby the cooling air is transported by an air channel (15) for cooling heat generated elements (12).
