Compressed air acoustic dampening system

摘要

The system (10) has a base body (12) permeated by a flow channel (24) in a middle longitudinal axis (18), where the flow channel ends into a discharge opening (46) at a front-sided end area of the base body and limited by a flow channel wall. A fin (44) radially inwardly projects into a free cross-section of the flow channel and extends from the discharge opening into the longitudinal axis. The fin has a profile that is tapered inwardly in a radial direction, where the profile is formed in a cross-sectional plane that is aligned perpendicular to the longitudinal axis.
