Abstract (en)

[origin: WO2012093945A1] A device has a ram element (1) engaged with at least one longitudinal rack (2) transferring impact energy to at least one kinetic energy rotary accumulator (13) converting 5 kinetic energy of progressive motion into kinetic energy of rotary motion. A solution is characterized by that at least one longitudinal rack (2) is engaged by at least one toothed wheel (7) with a crosswise rack (9) having its sliding direction inclined in relation to a sliding 10 direction of the longitudinal rack (2), wherein the crosswise rack (9) drives the kinetic energy rotary accumulator (13) by a transmission (12) increasing a rotation speed.
