ABSTRACT:
The invention relates to a pneumatic spring percussion mechanism comprising a driving piston moving back and forth in a housing of the percussion mechanism and a percussion piston, wherein a pneumatic spring is configured between the driving piston and the percussion piston. The movement of the driving piston can be transmitted to a percussion piston by means of said pneumatic spring. The driving piston can be driven by an electric linear motor and is connected to an aromatic of the linear motor, forming a single piece therewith. This arrangement makes it possible to eliminate the use of a conventional rotary motor and a crank mechanism to drive the driving piston.
