Abstract:
PURPOSE:To reduce the leak of cooling air, by providing a moving vane wheel with a protrusion which is to be fitted with that of a spacer wheel for a rotor and which is placed nearer the axis of the moving vane wheel than its vane groove on a side so that the protrusion of the moving vane wheel is annular along the total circumference of the wheel. CONSTITUTION:The protrusion 7 of a moving vane wheel 2, which is to be fitted with that 6 of a spacer wheel 4, is placed nearer the axis of the moving vane wheel 2 than its vane groove 11 so that the protrusion 7 of the moving vane wheel is annular along the total circumference of the wheel.
