A hydraulic machine having the following features is disclosed: - an impeller having a plurality of blades; - a spiral housing surrounding the impeller, and open toward the same by means of a circumferential slot, formed by two circumferential edges; - a traverse ring comprising two traverse ring shrouds, which are connected to each other by means of tie rods; - the spiral housing being connected to connecting surfaces of the traverse ring shrouds in the region of the circumferential edges. The hydraulic machine is characterized by the following features: - the regions of the circumferential edges are configured and/or disposed such that both extend parallel to the axis of rotation of the impeller, or form an angle alpha of no more than 11 degrees with the same.
L'invention concerne une machine hydraulique ayant les caractéristiques suivantes : une roue mobile présentant une pluralité de pales; un carter en volute qui entoure la roue mobile et est ouvert en direction de celle-ci par une fente périphérique formée par deux arêtes périphériques; un anneau de traverses, comportant deux couvercles d'anneau de traverses qui sont reliés l'un à l'autre par des tirants; le carter en volute est raccordé dans la région des arêtes périphériques à des surfaces de raccordement des couvercles d'anneau de traverses. Selon l'invention, les régions des arêtes périphériques sont formées et/ou disposées de sorte que celles-ci s'étendent toutes deux parallèlement à l'axe de rotation de la roue mobile ou forment avec celle-ci un angle alpha d'au plus 11 degrés.
