A hydraulic system for the control of boats, ships and crafts in general that comprises nozzles (1, 2) opposed at the end of the stem, having a Venturi tube throttling (8) or an internal diameter reduction by means of flanges (10), so as to be able to determine, following to the outlet of the fluid under pressure, the movement by reaction of the front part of the boat (N) and therefore to perform immediate leftward or rightward curvings according to the nozzle used, and/or corresponding nozzles (3, 4), placed nearby the stern and with similar backward function, while the operating for hydraulic reaction of both nozzles placed on the same side determines the parallel movement of the whole craft, for coming alongside to quays or for performing other manoeuvres.

La présente invention concerne un système hydraulique destiné à la manoeuvre de bateaux, de navires, et plus généralement d'engins. Ce système comprend à l'avant des gicleurs (1, 2) s'opposant l'un l'autre et présentant un étranglement (8) en tube de Venturi ou une réduction de diamètre interne obtenue au moyen de brides (10) de façon à être capable de régir, sous l'effet de la sortie de fluide sous pression, un mouvement de réaction de l'avant du bateau (N), et par conséquent d'infléchir la course du bateau vers la gauche ou la droite. Le dispositif comporte également, le cas échéant, des gicleurs correspondants (3, 4) qui sont situés à l'arrière et qui agissent de façon similaire vers l'arrière. Ainsi, en provoquant la réaction des deux gicleurs d'un même bord, le système détermine un déplacement parallèle de tout l'engin, par exemple pour accoster un quai ou pour effectuer d'autres manoeuvres.
