The present invention relates a hydraulic system (1) arranged between a first marine propulsion device (2, 42) and a second marine propulsion device (3, 43), which are each arranged so that they can rotate about a respective axis (6, 7, 46, 47) at a distance from one another. The system (1) comprises a first hydraulic piston-cylinder device (8, 50) and a second hydraulic piston- cylinder device (13, 55) arranged between said second propulsion device (2, 3, 42, 43) and an element (12, 17, 54, 59) fixed in relation to said axis (6, 7, 46, 47). Connecting the piston-cylinder devices (8, 13, 50, 55) to one another via a first hydraulic circuit (18, 60) and a second hydraulic circuit (19, 61) leads to that rotating of one propulsion device (2, 3, 42, 43) results in rotation of the other propulsion device (2, 3, 42, 43). This affords the function of a tie bar.
L'invention concerne un système hydraulique (1) disposé entre un premier dispositif de propulsion marin (2, 42) et un second dispositif de propulsion marin (3, 43) disposés de manière indépendante afin de pouvoir tourner autour d'un axe respectif (6, 7, 46, 47) à une distance définie l'un de l'autre. Le système (1) comprend un premier dispositif hydraulique à pistons-cylindres (8, 50) et un second dispositif hydraulique à pistons-cylindres (13, 55) disposés entre le second dispositif de propulsion (2, 3, 42, 43) et un élément (12, 17, 54, 59) fixé en relation avec l'axe (6, 7, 46, 47). La connexion des dispositifs à pistons-cylindres (8, 13, 50, 55) entre eux, par l'intermédiaire d'un premier circuit hydraulique (18, 60) et d'un second circuit hydraulique (19, 61) entraîne la rotation d'un dispositif de propulsion (2, 3, 42, 43) engendrant la rotation de l'autre dispositif de propulsion (2, 3, 42, 43), conférant ainsi la fonction de tirant.
