Patent ID: 8534377

Claim:
A coupling for a percussion mechanism with an electrodynamic linear drive; a drive element that is capable of being moved back and forth in a percussion mechanism housing by the linear drive, and a percussion element for striking a tool, the percussion element being capable of being moved relative to the drive element, the coupling comprising: a coupling that acts between the drive element and the percussion element, via which the movement of the drive element can be transferred to the percussion element; wherein, between the drive element and the percussion mechanism housing in the direction of impact, a reversing hollow space is provided at least one of in front of and/or behind the drive element; and wherein the reversing hollow space can be separated from ambient air external to the reversing hollow space in such a way that a reversing air spring that acts against at least one of the drive element and the percussion element is produced in the reversing hollow space; and wherein the coupling has an elastic element between the drive element and the percussion element.
