RESONATOR SILENCER FOR A RADIAL FLOW MACHINE, IN PARTICULAR FOR A RADIAL COMPRESSOR

摘要

A volute for a radial turbomachine is proposed. The turbomachine includes a radial compressor or a radial turbine. The volute is in particular for a radial compressor. The volute has a substantially annular cavity which is delimited at least by a first radial side surface. At least one substantially annularly circumferential groove is formed in the side surface.
