Abstract

The reversible hydroelectric machine operating as a pump or as a turbine is equipped with a first runaway limiting device (9) intervening after operation in turbine mode, and a second underspeed limiting device (10) intervening after an operation in pump mode, each of these devices giving rise, in the event of being triggered, to the closing of the root valve (3) of the forced passage (2) and, if the machine comprises one, that of the distributor, this being by one or more mechanical, hydraulic, pneumatic or electrical means (4-8).
