摘要

"PROCESS AND DEVICE FOR REDUCING PRESSURE SWING IN THE SUCTION TUBE OF A WATER TURBINE OR WATER PUMP OR WATER PUMP TURBINE". The present invention relates to a turbine or pump or pump turbine with a rotor having several guide vanes and a hub; with a housing having a distributor for regulating the current input to the rotor; with a suction pipe to drive water leaving the rotor that has an inlet diffuser. The present turbine or pump or pump turbine is characterized by the following characteristics: in the suction pipe an elongated displacement body is arranged; the upper end of the travel body chain is in the rotor hub area.
