CA 2637319

The invention relates to a device for controlling the filling and/or extraction of a fluid, for example, in relation to a pressurised fluid tank including a body having a connection end (516) which is equipped with engagement means that are intended to co-operate with complementary engagement means which are provided, for example, on a connection interface of a tank, a member (17) for opening a valve that can move in relation to the body, actuation means (250) which can move the opening member (17) selectively and which can move between a running position and a stopped position corresponding respectively to an operating position and a rest position of the opening member (17) and a hole (105) which can receive a removable outlet or inlet coupling (75) for the distribution of the fluid. The invention is characterised in that the device includes retractable locking means (55) which are used to lock the actuation means (250) in the running position and which are designed to co-operate with the hole (105), such that, when there is no coupling (75) connected to the control device in the corresponding hole, the locking means (55) are biased towards the retracted position, thereby preventing the actuation means (250) from being stably maintained in the running position.

Dispositif de commande du remplissage et/ou du soutirage de fluide à partir notamment d'un réservoir de fluide sous pression comportant un corps ayant une extrémité (516) de connexion pourvue de moyens d'accrochage destinés à coopérer avec des moyens d'accrochages complémentaires, notamment d'une interface de connexion d'un réservoir, un organe (17) d'ouverture de vanne mobile relativement au corps, des moyens (250) d'actionnement aptes à déplacer sélectivement l'organe (17) d'ouverture, les moyens (250) d'actionnement étant mobiles entre une position de marche et une position d'arrêt correspondant respectivement à une position de travail et une position de repos de l'organe (17) d'ouverture, un orifice (105) destiné à accueillir un raccord (75) amovible de sortie ou d'arrivée pour assurer la distribution de fluide, caractérisé en ce qu'il comporte des moyens (55) de verrouillage escamotables des moyens (250) d'actionnement dans la position marche, les moyens (55) de verrouillage escamotables étant conformés de façon à coopérer avec l'orifice (105), de façon que, lorsque qu'un raccord (75) n'est pas connecté au dispositif de commande dans l'orifice, les moyens (55) de verrouillage sont sollicités vers leur position escamotée, empêchant le maintien stable des moyens (250) d'actionnement dans la position marche.
