The invention relates to an assembly comprising an electromechanical device and a self-sealing valve, and in particular, to any inflatable device(16) that includes the assembly. In one embodiment, the assembly comprises a valve housing defining an opening (26) through which fluid can be provided to the inflatable device, a flexible diaphragm assembly (40) that is configured to self-seal the opening with sufficient fluid pressure in the inflatable device and to open under sufficient fluid pressure from a fluid moving device (110), to provide fluid through the opening to and seal the inflatable device. The assembly further comprises an electromechanical device (50) including an actuating arm, (52) having a first position (53) in which the actuating arm urges open the self~sealing valve and a second position in which the actuating arm does not act upon the self-sealing valve, so as to regulate an amount of fluid within the inflatable device. With this arrangement, a small, low power, low duty cycle electromechanical device can be used.
L'invention concerne un ensemble comprenant un dispositif électromécanique et une soupape auto-étanche, et en particulier tout dispositif gonflable (16) comprenant cet ensemble. Selon une variante, l'ensemble comporte un logement de soupape qui définit une ouverture (26) pour l'alimentation du dispositif gonflable en fluide, un ensemble diaphragme flexible (40) assurant l'auto-étanchéité de l'ouverture, avec une pression de fluide suffisante dans ce dispositif, et s'ouvrant lorsqu'une pression de fluide suffisante est exercée par un dispositif de déplacement de fluide (110), ce qui permet d'acheminer le fluide via l'ouverture et d'assurer l'étanchéité du dispositif gonflable. L'ensemble comprend en outre un dispositif électromécanique (50) à bras actionneur (52). Dans une première position (53), ce bras ouvre la soupape, et dans une seconde position il n'agit pas sur ladite soupape, de manière à réguler la quantité de fluide dans le dispositif gonflable. La configuration décrite permet d'utiliser un dispositif électromécanique de petite taille, consommant peu d'énergie, à faible coefficient d'utilisation
