Abstract
A combustion-operated setting tool for driving fastening elements in a constructional component includes a device (30) for adjusting setting energy applied to a setting piston (15) axially displaceable in a guide space (4) of a piston guide (13). The adjusting device (30) has a separation member (31) adjustably arranged between the receptacle (18) and the guide space (14) of the piston guide (13) and dividing the combustion chamber (20) in a first sub-chamber (21) arranged between the receptacle (18) and the separation member (31) and a second sub-chamber (22) arranged between the separation member (31) and the guide space (14) of the piston guide (13), the separation member (31) having a plurality of through-openings (34, 35) for controlling flow of the combustion gases into the guide space (14) of the piston guide (13), with an active opening cross-section of at least a portion of the through-openings (34, 35) changing dependent on an adjustable position of the separation member (31).
