Abstract

A driving device, comprising a hand-held housing with a piston element arranged therein for the transmission of energy to a fastening element to be driven in a driving direction, a propellant charge, and a combustion chamber, which is arranged between the propellant charge and the piston element and extends around a central axis, and an actuator, by which the energy to be transmitted from the propellant charge to the piston element can be varied in such a way that the energy can be set, wherein a venting channel connected to the combustion chamber can be exposed by means of a movable slide of the actuator, wherein the venting channel opens out into the combustion chamber by a vent opening, which can be partially or completely covered by the slide, and wherein a cross-sectional area of the vent opening increases in the driving direction.
