DESCRIPTION
La présente invention concerne un système de compensation automatique de densité pour engin immergé notamment pour petit sous-marins.DESCRIPTION
The present invention relates to an automatic density compensation system for submerged vehicle, in particular for small submarines.
Les systèmes actuels de compensation de densité se font par le remplissage ou la vidange de réservoirs (ballasts). Le principe demande, sur les petits engins, un réglage manuel qui doit être refait à chaque modification des masses contenues dans l'ensemble immergé. Sur les engins plus sophistiqués les masses modifiées sont introduites en données dans un ordinateur qui compense, aux moyens de ballasts, la densité de l'ensemble.Current density compensation systems are done by filling or emptying tanks (ballasts). The principle requires, on small machines, a manual adjustment which must be redone with each modification of the masses contained in the submerged assembly. On more sophisticated vehicles, the modified masses are entered into data in a computer which compensates, by means of ballasts, for the density of the whole.
Tous ces moyens sont longs et fastidieux.All these means are long and tedious.
Le dispositif selon l'invention permet, pour les petits engins, de réaliser cette compensation automatiquement. I1 comporte, en effet, un ensemble support piston qui en se mouvant, sous l'action du poids de cette masse, engendre la modification d'un volume d'air déplaçant un poids de liquide environnant équivalent à celui de la masse introduite ou retirée. Un ressort étalonné contrôle le déplacement du piston afin que le poids du liquide déplacé par la modification du volume d'air soit équivalent à la masse placée sur le support. Une amélioration du dispositif permet, par l'intermédiaire d'un système à balancier, de mouvoir un piston dans un cylindre à l'intérieur de l'engin et de déplacer, à travers une vanne de communication vers l'extérieur, une quantité de liquide dont le poids est égal au poids de la masse introduite ou retirée.Le système de transmission entre le support et le piston peut être remplacé par d'autre systèmes et en particulier par un ensemble hydraulique. Une vanne permet la communication du liquide contenu dans le cyclindre et le liquide environnant pour réaliser la compensation et assure ensuite par sa fermeture une isolation de pression entre le liquide extérieur et l'intérieur du cylindre.Le support peut avantageusement être un siège de passager pour sous-marin, ou par exemple, un support pour équipement tel que instrument, bouteilles, vide poche etc... The device according to the invention makes it possible, for small machines, to carry out this compensation automatically. I1 comprises, in fact, a piston support assembly which by moving, under the action of the weight of this mass, generates the modification of an air volume displacing a weight of surrounding liquid equivalent to that of the mass introduced or withdrawn . A calibrated spring controls the displacement of the piston so that the weight of the liquid displaced by the modification of the air volume is equivalent to the mass placed on the support. An improvement of the device makes it possible, by means of a balance system, to move a piston in a cylinder inside the machine and to move, through a communication valve to the outside, an amount of liquid whose weight is equal to the weight of the mass introduced or withdrawn. The transmission system between the support and the piston can be replaced by other systems and in particular by a hydraulic assembly. A valve allows the communication of the liquid contained in the cylinder and the surrounding liquid to make the compensation and then ensures by its closing a pressure isolation between the external liquid and the interior of the cylinder. The support can advantageously be a passenger seat for submarine, or for example, a support for equipment such as an instrument, bottles, empty pocket, etc.

Le liquide (6) est en communication avec l'extérieur (9) par la vanne (8).FIG. 2 represents the device equipped with a transmission system (support (1) - piston (3)) constituted by a pendulum (9). The cylinder (7) is located inside the machine. The liquid (6) is in communication with the outside (9) through the valve (8).
La figure 3 représente le dispositif équipé d'un système de transmission (support (1) - piston (3)) constitué par un ensemble hydraulique (9).FIG. 3 represents the device equipped with a transmission system (support (1) - piston (3)) constituted by a hydraulic assembly (9).
Le dispositif selon l'invention est plus particulièrement destiné à équiper les petits sous-marins et à compenser automatiquement les différences de poids qui y sont introduites, en particulier les passagers et les équipements tels que instruments, bouteilles, vide poche etc.... The device according to the invention is more particularly intended to equip small submarines and to automatically compensate for the differences in weight which are introduced therein, in particular the passengers and the equipment such as instruments, bottles, empty pocket, etc.
