Abstract (en)
[origin: EP1221359A1] Device, especially a hand machine tool, comprises at least one vibrationally excited first unit, at least one second unit (10) connected via a vibration-insulating device (14) to the first unit, and an operating force impinging upon the vibration-insulating device during operation. The vibration-insulating device has an actuator (22) via which the operating force (12) is at least partially compensated with controlling torque (24). The controlling torque is at least extensively independent of the vibration to be insulated. An Independent claim is also included for a hand machine tool, especially a hammer drill or a chisel hammer, comprising a vibration-insulating device. Preferred Features: A maximal compensating frequency of the actuator is lower than an excitation frequency.
