Abstract:
1. An explosion-power operated setting tool , for driving fastening elements in a structural component, comprising a housing ( 11 ); a piston guide ( 13 ) arranged, at least partially, in the housing ( 10 ) and having a guide chamber ( 14 ); a setting piston ( 16 ) displaceable arranged in the guide chamber ( 14 ) of the piston guide ( 13 ); and a resetting device ( 30 ) including a lever-shaped resetting member ( 31 ) for returning the setting piston ( 15 ) from an end position ( 26 ) thereof facing in the setting direction ( 60 ) in an initial position ( 25 ) thereof and having a rear surface ( 36 ), a bearing section ( 43 ) for supporting the resetting member ( 31 ), and a damping member ( 44 ) adjoining the bearing section ( 43 ) for damping the resetting member ( 31 ) upon the resetting member ( 31 ) impacting the bearing section ( 43 ) and having a bearing surface ( 46 ) which the rear surface ( 36 ) of the resetting member ( 31 ) abuts, the bearing surface ( 46 ) of the damping member ( 44 ) having a profile substantially corresponding to a profile of the rear surface ( 36 ) of the resetting member ( 31 ), wherein the bearing surface ( 46 ) of the damping member ( 44 ) has, with respect to the lever-shaped resetting member ( 31 ), a concave profile.
