Abstract

A gas supply for feeding at least two components of a combustion mixture to a combustion chamber has gas dosing cylinders (16, 19) respectively for oxygen and fuel of which the gas filling pressures are controllable or adjustable by a pressure regulator (15) and a throttle valve (18) respectively. The mixture ratio of the gases can thus be changed between each filling of the dosing devices by control of the setting motor (35) of the pressure regulator. This setting can also change the filling pressure in the combustion chamber (10). The length of the piston stroke in the dosing cylinders can also be controlled.
