Abstract

A driving device, comprising a hand-held housing with a piston element arranged therein for 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 energy to be transmitted from the propellant charge to the piston element can be varied in such that the energy can be set, wherein the combustion chamber has an internal thread and a cylindrical guiding portion, wherein the actuator is arranged in the combustion chamber and has an external thread in engagement with the internal thread and a bearing for mounting the actuator in the guiding portion, wherein a thread gap spacing between the external and internal threads is greater than a bearing gap spacing between the bearing and the guiding portion.
