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.
A device for step-wise release of pressurized gases coprising means for controlling flow of gases at variable pressure and volume from a source to atmosphere as a function of accumulated volume and/or pressure of gases, said means including a flow conduit defined at least in part by a plurality of gate valves in series and terminating at a discharge port for discharge to atmosphere, each of said valves including a housing having a transversely movable valve member, said conduit including an expansion space for expansion of gases between successive valve members, successive valve members and their associated orifices being on diametrically opposite sides of said conduit so that successive orifices are eccentric with respect to the longitudinal axis of said conduit, and means for adjusting the gate valves as a function of the accumulated volume stream.
Device for the step-wise pressure release on the expansion of, in particular hot gases with highly different volume streams, characterized in that at least two adjustable plate valves (1, 2, 3) are arranged in series one behind the other, that the orifice (1', 2', 3') of each plate valve (1, 2, 3) is arranged eccentrically in relation to its central longitudinal axis (4), with the orifices (1', 2', 3') of successive plate valves (1, 2, 3) each arranged on opposite sides in relation to the rectilinearly extending, continuous, central longitudinal axis (4), to all the plate valves (1, 2, 3), and means for adjusting the plate valves (1, 2, 3) as a function of the accumulated volume stream (RG).
