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