A method for producing a geraeuschlosen or substantially stroemungsvorganges by means of a throttle - or damping device and device for carrying out this method

摘要

For obtaining a noiseless or substantially noiseless process of a flow passing through a throttle or damper device, the flow is given a speed increase with increasing acceleration in the direction of flow. Further, at least a substantial part of the dynamic component of the energy state of the flow is quenched within or immediately after the device by means of a counter-directed flow having a similar dynamic component. The invention also concerns a throttle or damper device for such a noiseless or substantially noiseless process of a flow.
