Abstract: A compressor recirculation valve having features for mitigating the “rush” noise caused when the valve opens and compressed recirculation air rushes through the valve into the compressor inlet. The features for mitigating rush noise include a generally annular wall that projects from the valve seat and surrounds the valve member. The radially inner surface of the wall can be conical and can include radially inwardly projecting teeth between which are V-shaped grooves.
