The Pelton turbine includes a wheel disc with buckets mounted within a casing on a rotatable drive shaft. At least one nozzle is provided for expelling a fluid jet tangentially of the disc onto the buckets. A partition divides the interior of the housing into a spray fluid and outlet region and an upper ventilation region. The driving fluid falls from the buckets into a sump in the outlet region while residual fluid is wiped off the turbine wheel by the partition. The ventilation region allows ventilation of the casing and also produces a flow of gas for increasing the pressure in the sump to improve the outflow of fluid. |
