摘要
<p>The body (1) has a volute (10) extending in crown and comprising an annular inlet i.e. diffuser, delimited between radial planes perpendicular to a wheel axis (A). The inlet is opposite to a periphery of a wheel. An outlet duct (12) is provided in the continuity of the volute and extending tangentially to the inlet. A tongue (11) is provided at a junction of the volute and the outlet duct. The tongue comprises a side portion extending along one of the radial planes. The tongue comprises a central portion connected to the side portion.</p>
