Abstract
The present invention relates to a combustion-engined setting tool for driving fastening elements, such as nails, bolts, pins in a constructional component, with a fuel guide () extending from a fuel source () to a combustion chamber () and with at least on electronically controlled valve () which is arranged in the fuel guide () between the fuel source () and the combustion chamber (), and with a control unit (), including at least one actuation means () with which the valve () is opened for a predetermined time period. For improving, it is proposed to arranged in the fuel guide () a storage chamber () between the electronically controlled valve () and the combustion chamber (). The storage chamber becomes filled with fuel through the electronically controlled valve already before the setting tool is pressed against a constructional component, enabling rapid, following one after another, setting processes.
