Abstract

A method and device for driving a linearly movable component, wherein a pressurized fluid is generated by feeding a given volume of oxygen into a combustion space connected to a piston/cylinder configuration and feeding a given volume of fuel into the combustion space for each motion stroke of the piston/cylinder configuration beore the start of the motion stroke, the given volume of oxygen is sufficient for the combustion of the fuel, the given volume of fuel is sufficient for generating the pressurized fluid, the oxygen and fuel are ignited in the combustion space, and the pressurized fluid is feed into the piston/cylinder configuration for driving a piston of the piston/cylinder configuration and a linearly movable component connected to the piston.
