Abstract
The exhaust pipe of a turbine accommodates in the inner portion (3) thereof a guide (8). The inner side surface of the guide (8) is essentially the surface of a body of revolution about an axis coincident with the axis (6) of the turbine. The guide (8) is disposed so that one of its ends (9) adjoins the outer ends (10) of the blades (4) of the runner (5) of the turbine. In accordance with the invention, the guide (8) is adapted to vary the area of the flow cross-section of the inlet portion (3) of the exhaust pipe.
