The device comprises at least one flap member (3) having a rear flap portion that runs in a plate plane, and a forward portion, as seen in the direction of motion (F). The forward portion (8) is connected to the object (2) in such manner that the flap portion (17) can be moved in the fluid transverse to the plate plane and between two positions which are on their respective sides of a neutral place (P). Furthermore, the device comprises an actuating means (8, 9) which allows a freely oscillating motion of the flap member (3; 61, 62), and a drive unit (6) for actuating the flap member (3; 61, 62) when the valve of an oscillation amplitude of the flap member (3; 61, 62) is less than a predetermined threshold value.
L~invention a pour objet un dispositif comprenant au moins un élément formant clapet (3) doté d~une partie de clapet arrière qui court dans un plan plat et une partie avant, comme illustré dans la direction du mouvement (F). La partie avant (8) est reliée à l~objet (2) de telle sorte que la partie de clapet (17) puisse se déplacer dans le liquide transversalement au plan plat et entre deux positions qui se trouvent sur leurs côtés respectifs d~un point neutre (P). En outre, le dispositif comprend des connecteurs de manAEuvre (8, 9) permettant un mouvement oscillant libre de l~élément formant clapet (3; 61, 62), ainsi qu~une unité d~entraînement (6) pour actionner l~élément formant clapet (3; 61, 62) lorsque la soupape d~une amplitude d~oscillation de l~élément formant clapet (3; 61, 62) est inférieure à une valeur de seuil prédéterminée.
