Abstract

The invention relates to a device for the step-wise pressure release on the expansion of, in particular hot, gases with highly different volume streams. In a device of this type, reaching or even exceeding the speed of sound is to be safely prevented. This is achieved in that at least two adjustable plate valves are arranged in series one behind the other, that the orifice of each plate valve is arranged eccentrically in relation to its central longitudinal axis, with the orifices of successive plate valves each arranged on opposite sides in relation to the rectilinearly extending, continuous central longitudinal axis common to all the plate valves and that the adjustment of the plate valves is effected as a function of the accumulated volume stream.
