114 238.6-2301 Mitsubishi Jukogyo Kabushiki Kaisha Patentansprüche114 238.6-2301 Mitsubishi Jukogyo Kabushiki Kaisha Patent Claims 1. Radialturbinenmaschine, umfassend ein Turbinen-Laufrad, bei dem sich die Mittellinie jeder Turbinen-Laufschaufel in einem Querschnitt senkrecht zur Drehachse zur Rückseitenfläche der Schaufel mit einem sich vergrößernden, die Drehachse als Mittelpunkt aufweisenden Radius weiter von einer radialen geraden Linie entfernt, die durch die Drehachse und einen Schnittpunkt verläuft, an dem die Mittellinie der Schaufel und eine Nabenlinie einander schneiden.1. A radial turbine machine comprising a turbine impeller, in which the centerline of each turbine impeller blade in a cross section perpendicular to the axis of rotation towards the back surface of the blade with an increasing radius centered on the axis of rotation further away from a radial straight line passing through the axis of rotation and an intersection point where the centerline of the blade and a hub line intersect. 2. Maschine nach Anspruch 1, dadurch gekennzeichnet, daß die Mittellinie der Laufschaufel in einem Querschnitt senkrecht zur Drehachse eine gerade Linie ist.2. Machine according to claim 1, characterized in that the center line of the blade in a cross section perpendicular to the axis of rotation is a straight line. 3. Maschine nach Anspruch 1, dadurch gekennzeichnet, daß die Mittellinie der Laufschaufel in einem Querschnitt senkrecht zur Drehachse eine gekrümmte Linie ist.3. Machine according to claim 1, characterized in that the center line of the blade is a curved line in a cross section perpendicular to the axis of rotation.
