Fuel gas-operated drive-in device having valve component

摘要

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