  • Two-stage/single-stage reversible pump-turbine with supplying pump
    Patent number: 4217077
    Abstract: In a hydroelectric facility, a vertically mounted rotatable shaft is connected to a motor-generator and carries a pump-turbine with a supplying pump disposed below and immersed in water, the supplying pump disengaging from the shaft when the pump-turbine is driving the motor-generator and engaging the shaft when the motor-generator is driving the pump-turbine and supplying pump, thereby providing a two-stage pumping mode and a single-stage generating mode.

  • Flat throttling gate
    Patent number: 3996750
    Abstract: A flat throttling gate for bulb-type turbines and the like which is installed in a draft tube of the turbine. The gate has a central cutout of arcuate configuration flanked by a pair of ramps which cam a pair of masks into respective chambers flanking the guide slot for the slide body. Actuating mechanisms, e.g. springs, bias the masks against the valve body. In the withdrawn position of the valve body, the throttling cutout boundary, the masks and the wall of the draft tube define a circular flow cross section. In the inserted position of the valve body, a narrow flow cross section is provided between the wall of the draft tube or a lining thereof and a boundary of the cutout.
