A cet effet, l'invention concerne un dispositif d'orientation d'un navire notamment d'un voilier du type comportant une barre reliée à une mèche portant un safran directionnel, dispositif caractérisé en ce que le safran directionnel est pourvu à sa base d'un plan porteur réglable, formant avec le safran une drive en forme de T. To this end, the invention relates to a device for orienting a ship, in particular a sailboat of the type comprising a bar connected to a wick carrying a directional rudder, device characterized in that the directional rudder is provided at its base d '' an adjustable bearing surface, forming with the rudder a T-shaped drive

Ce dispositif permet à la fois de contrôler l'orientation directionnelle du navire et de régler l'incidence du plan porteur ayant pour fonction de contrôler l'assiette longitudinale du navire. This device makes it possible both to control the directional orientation of the ship and to adjust the incidence of the carrier plane, the function of which is to control the longitudinal attitude of the ship.

Suivant une autre caractéristique de l'invention, le plan porteur est constitué d'un flotteur horizontal intitulé "foil". According to another characteristic of the invention, the carrier plane consists of a horizontal float entitled "foil".

Suivant une autre caractéristique de l'invention, la mèche est maintenue par un étrier de jaumière monté pivotant sur un axe transversal horizontal à l'une de ses extrémités et relié à un vérin hydraulique par son autre extrémité, ce vérin commandant le réglage de l'incidence du plan porteur. According to another characteristic of the invention, the wick is held by a jaumière bracket mounted to pivot on a horizontal transverse axis at one of its ends and connected to a hydraulic cylinder by its other end, this cylinder controlling the adjustment of the impact of the carrier plan.

Suivant une autre caractéristique de l'invention, le vérin commande la rotation autour de l'axe horizontal de l'ensemble formé par le plan porteur, le safran directionnel, la miche et l'étrier de jaumière afin de régler l'incidence du plan porteur. According to another characteristic of the invention, the jack controls the rotation about the horizontal axis of the assembly formed by the carrier plane, the directional rudder, the loaf and the jaumière stirrup in order to adjust the incidence of the plane carrier.

Suivant une autre caractéristique de l'invention, le circuit hydraulique comporte des canalisations de distribution du fluide munies de vannes de réglage, les canalisations de retour du fluide vers la bâche étant pourvues d'organes étrangleurs, limiteurs de débit. According to another characteristic of the invention, the hydraulic circuit includes pipes for distributing the fluid provided with adjustment valves, the pipes for returning the fluid to the tank being provided with throttling members, flow limiters.

La présente invention sera mieux comprise à l'aide d'un mode de réalisation d'un dispositif d'orientation conforme à l'invention, représenté schématiquement, à titre d'exemple non limitatif, sur les dessins ci-joints dans lesquels
- la figure 1 est une vue en perspective du dispositif d'orientation,
- la figure 2 est un schéma du circuit hydraulique alimentant le vérin.The present invention will be better understood using an embodiment of an orientation device according to the invention, shown schematically, by way of nonlimiting example, in the accompanying drawings in which
FIG. 1 is a perspective view of the orientation device,
- Figure 2 is a diagram of the hydraulic circuit supplying the cylinder.

Suivant la figure 1, le dispositif d'orientation 1 comporte de façon connue une barre directionnelle 2 reliée à une mèche verticale 3, cette mèche supportant un safran directionnel 4. La mèche 3 est maintenue dans l'étrier de jaumière 6 par des butées, non représentées sur cette figure, afin d'empêcher tout déplacement vertical de la mèche dans l'étrier de jaumière 6. Le safran 4 est pourvu à sa base d'un plan porteur réglable 5. Ce plan porteur est constitué d'un flotteur horizontal intitulé "fois". Ce plan porteur réglable permet de contrôler l'assiette longitudinale du navire. According to FIG. 1, the orientation device 1 comprises, in a known manner, a directional bar 2 connected to a vertical wick 3, this wick supporting a directional rudder 4. The wick 3 is held in the jaumière caliper 6 by stops, not shown in this figure, in order to prevent any vertical movement of the wick in the selvedge stirrup 6. The rudder 4 is provided at its base with an adjustable support plane 5. This support plane consists of a horizontal float titled "times". This adjustable bearing plane makes it possible to control the longitudinal attitude of the ship.

La mèche 3 traverse un étrier jaumière 6 monté pivotant à son extrémité 7 sur un axe transversal horizontal 8 et relié à son extrémité 9 à un vérin hydraulique 10. Le vérin hydraulique 10 commande l'incidence du plan porteur 5. The wick 3 passes through a jaumière caliper 6 pivotally mounted at its end 7 on a horizontal transverse axis 8 and connected at its end 9 to a hydraulic cylinder 10. The hydraulic cylinder 10 controls the incidence of the bearing plane 5.

Ainsi, l'orientation du safran 4 permet de contrôler la direction du navire, cette orientation étant obtenue par rotation de la mèche tournant dans l'étrier de jaumière 6.Thus, the orientation of the rudder 4 makes it possible to control the direction of the ship, this orientation being obtained by rotation of the wick turning in the jaumière caliper 6.

Le réglage de l'incidence du plan porteur intitulé "foil" est obtenu par la rotation autour de l'axe transversal horizontal 8 de l'ensemble formé par le plan porteur 5, le safran 4, la mèche 3 et l'étirier de jaumière 6. The adjustment of the incidence of the carrier plane entitled "foil" is obtained by the rotation around the horizontal transverse axis 8 of the assembly formed by the carrier plane 5, the rudder 4, the wick 3 and the ridge 6.

La rotation de cet ensemble est rendue possible par l'action d'un vérin hydraulique 10 à double effet. En raison des forces extrêmement importantes qui sont en jeu, la rotation autour de l'axe horizontal 8 nécessite un vérin hydrauliqu 10 très puissant. The rotation of this assembly is made possible by the action of a double-acting hydraulic cylinder 10. Due to the extremely large forces involved, rotation around the horizontal axis 8 requires a very powerful hydraulic cylinder 10.

Selon la figure 2, le vérin hydraulique 10 à double effet, dont le piston 11 est relié à l'étrier de jaumière 8, est alimenté à partir de la bâche 12 par des canalisations de distribution 13, 14, 15, 16. Une pompe 17 permet d'alimenter le vérin 10. Les canalisations de distribution 13, 14, 15, 16 sont pourvues chacune de vannes de réglage 18. I1 est prévu également sur les canalisations de retour 14, 16 à la bâche, des organes étrangleurs limiteurs de débit 19, 20. Ces organes étrangleurs limiteurs de débit sont placés dans les canalisations de distribution 14 et 16 pour éviter les changements brutaux d'incidence en cas de fausse manoeuvre des vannes de réglage 18. According to FIG. 2, the double-acting hydraulic cylinder 10, the piston 11 of which is connected to the jaumière caliper 8, is supplied from the cover 12 by distribution pipes 13, 14, 15, 16. A pump 17 is used to supply the jack 10. The distribution pipes 13, 14, 15, 16 are each provided with adjustment valves 18. I1 is also provided on the return pipes 14, 16 to the tank, restricting restrictors of flow 19, 20. These flow restricting throttle members are placed in the distribution pipes 14 and 16 to avoid sudden changes in incidence in the event of incorrect operation of the control valves 18.

Les vannes 18 sont couplées et forment un ensemble pouvant présenter trois situations distinctes. Dans la première situation, toutes les vannes sont fermées ; dans la seconde situation les vannes 13 et 16 sont ouvertes et les vannes 14, 15 sont fermées ; et dans la troisième situation les vannes 14, 15 sont ouvertes et les vannes 13 et 16 sont fermées.  The valves 18 are coupled and form an assembly which can present three distinct situations. In the first situation, all the valves are closed; in the second situation the valves 13 and 16 are open and the valves 14, 15 are closed; and in the third situation the valves 14, 15 are open and the valves 13 and 16 are closed.
