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.

摘要： The invention relates to a fuel-operated firing device for driving securing elements into a substrate, comprising at least one main combustion chamber for a fuel, a driving piston that can be driven out of the main combustion chamber in a firing direction by expandable gases, and a pre-chamber with which an ignition device is associated and in which a pressure acting on the main combustion chamber can build up prior to a fuel-air mixture being ignited in said main combustion chamber. In order to improve the efficacy and/or functionality during the driving in of securing elements, a detection system is associated with the driving piston, said detection system being connected to an electronic feedback control device for control purposes, in order to detect an initial position of the driving piston prior to a firing operation.
