Patent ID: 8387845

Claim:
A setting tool for driving fastening elements into a constructional component, comprising: a piston guide ( 13 ) having a hollow chamber ( 14 ); a setting piston ( 20 ) axially displaceable in the hollow chamber ( 14 ) of the piston guide ( 13 ) for driving the fastening elements into the constructional component; a bolt guide ( 12 ) adjoining the piston guide ( 13 ) in a setting direction of the setting tool for guiding the fastening elements; and a piston stop device ( 30 ) arranged at an end region of the hollow chamber ( 14 ) adjacent to the bolt guide ( 12 ) for controlling the axial displacement of the setting piston ( 20 ) when the setting piston ( 20 ) drives the fastening elements into the constructional component, with the piston stop device ( 30 ), the piston stop device ( 30 ) having: a damping element ( 31 ) supported against a stop ( 15 ), and a stop member ( 32 ) for the setting piston ( 20 ) and adjoining the damping element ( 31 ) in a direction toward the hollow chamber ( 14 ) of the piston guide ( 13 ), wherein each of the damping element ( 31 ), the stop member ( 32 ), the stop ( 15 ), have respective surfaces ( 33 , 34 , 35 , 36 ) arranged axially opposite each other, with at least one of the respective, axially opposite surfaces ( 33 and 34 , 35 and 36 ) being formed as an inclined surface (S) enclosing a respective opposite surface such that an angle (α) between at least one of pairs ( 33 , 34 ) and ( 35 , 36 ) of axially opposite surfaces ( 33 and 34 , 35 and 36 ) is formed, and wherein the angle (α) is in a range of 2° to 20°.
