| 摘要 |
The invention relates to a hand-held working tool, comprising a first unit, powered by a vibration on operation and a second unit which may be displaced relative to the first unit. A vibration isolation device is arranged between the first and second unit, comprising an actuator, for generation of a control force, by means of which the operational force acting in the working direction (A) between the first and the second unit may be at least partly compensated. The actuator is pneumatically operated and comprises an air spring for vibration isolation. A working piston in an air spring percussion device on the working tool serves to supply compressed air for the air spring. Alternatively, the compressed air can be supplied by the oscillating relative movement between the first unit and the second unit.
