Abstract (en)

[origin: EP2243580A2] The mechanism (5) has a longitudinal striking axle is movably arranged in a flying piston (13) and an exciter piston (12). A pneumatic chamber (19) is closed by a metallic guide cylinder (10), the flying piston and the exciter piston, and a driving unit (3) i.e. electric motor, periodically moves the exciter piston. The flying piston is stimulated to a periodical movement between the flying piston and exciter piston, and an inner wall (11) of the guide cylinder and a lateral surface of the flying piston and exciter piston are provided with thermosetting plastic and/or thermoplastic material.
