Abstract (en)

[origin: WO2022207326A1] Disclosed is a driving tool comprising a hand-held housing in which a piston member is arranged for transmitting energy to a fastening element to be driven in in a driving direction, an especially replaceable propellant charge, a combustion chamber which is located between the propellant charge and the piston member and which extends about a central axis, and an actuator, by means of which the energy to be transmitted from the propellant charge to the piston member can be varied, wherein a venting duct that is connected to the combustion chamber can be opened by means of a movable slider of the actuator, the venting duct running into the combustion chamber via a venting port which can be partly or fully covered by the slider and a cross-sectional area of which increases in the driving direction.
