Claim:
A fusegate for a water structure, comprising: a solid element comprising a wall with a retaining height h RN ; a chamber formed at the base of the solid element between the solid element and a support surface for the solid element; and a feeder operably pressurising the chamber, enabling the chamber to be filled with water to create under the solid element a thrust directed upwards, so as to allow the tilting of the solid element by tilting when the water reaches a predefined level h MAX upstream of the fusegate; the feeder further comprising an intake port for the chamber, the intake port being provided with two compartments delimited by an internal wall, the two compartments communicating with each other through at least one passage provided at the top part of the intake port at a height corresponding substantially to the predefined water level h MAX for tilting of the fusegate, one of the compartments having at least one opening for entry of water into intake port, disposed at a height h less than the retaining height h RN , and the other compartment communicating with the chamber.
