Abstract:
Disclosed is a device for reducing flow noise. In order to achieve a low flow noise, the device includes inlet apertures for receiving a fluid flow, chambers into which one or more inlet apertures open up, a cross-sectional area of a single chamber being larger than a combined flow cross-sectional area of the inlet apertures opening up thereto, and chamber-specific outlet apertures for forwarding the fluid flow from the chamber, a flow cross-sectional area of each outlet aperture being smaller than the cross-sectional area of the chamber, and the combined flow cross-sectional area of all outlet apertures of the single chamber being larger than the combined flow cross-sectional area of the inlet apertures opening up into said chamber.
