The invention relates to a drive-in device comprising a drive-in piston (4) guided in a cylinder (3) for driving a nail component into a work piece, a combustion chamber (2) arranged on the drive-in piston (4), and which can be filled with an incendive gas mixture, a charge component (6) for producing an over-pressure of the gas mixture, and a touch component (18, 22) for recognising a pressing of the drive-in device on a work piece, wherein the combustion chamber (2) is connected to an outer space via a valve component (15), wherein the valve component (15) is controlled in accordance with a position of the touch component (18, 22), such that, in the event of a non-ignition, the over-pressure of the gas mixture can escape via the valve component (15) after a removal of the drive-in device. |
