Abstract (en)
[origin: WO2017102469A1] The invention relates to a driver device, comprising a driving piston (4) for driving a nail element into a workpiece, which driving piston is guided in a cylinder (3), and comprising a combustion chamber (2) arranged adjoining the driving piston (4). In the course of a driving process, a pressure increase occurs in the combustion chamber as a result of a combustion process. Before the driving process, the driving piston (4) is held in an initial position by means of a piston holder (10). The piston holder (10) comprises a piezoelectric actuator (21).
