Abstract (en)
[origin: WO2012116880A1] The invention relates to a volute (20) for a radial turbomachine, such as a radial compressor (100) or a radial turbine, in particular for a radial compressor (100) of this type. Said volute (20) has a substantially annular cavity (30) which is delimited at least by a first radial side surface (21, 23). According to the invention, at least one substantially annularly circumferential groove (50) is formed in said side surface (21, 23).
