Abstract (en)
[origin: EP2210711A1] The mechanism (1) has a work space (10) with two sections (30, 31) that are surrounded by respective electromagnets (4, 5). An impact body (2) is movable within the work space along an impact axis (11) and consists of a magnetizable material. An anvil (3) has an impact surface (17) that defines the work space in an impact direction (12). A spring element i.e. spiral spring (70), subjects the impact body in each position in the work space with force towards the anvil. The spring element exhibits progressive characteristic with which a spring rate increases against the impact direction.
