PYROTECHNIC DRIVING DEVICE

摘要

The invention relates to a driving device, comprising a hand-held housing having an energy transmission element accommodated therein for transmitting energy to a fastening element to be driven in, an exchangeable propellant charge and a combustion chamber arranged between the propellant charge and the energy transmission element, said combustion chamber extending about a central axis, wherein the combustion chamber is subdivided by means of a dividing member having a number of interruptions into a first subchamber adjoining the propellant charge and at least one second subchamber adjoining the energy transmission element, wherein an ejection region, enclosing a central axis, for the propellant charge is provided in the first subchamber, said ejection region extending between the propellant charge and a central region of the dividing member, wherein the ejection region is bounded at the central region of the dividing member by a closed surface of the dividing member.
