Title
(EN) HYDROGEN GENERATOR WITH LOCKING DOOR
(FR) GÉNÉRATEUR D'HYDROGÈNE DOTÉ D'UNE PORTE VERROUILLABLE
Abstract
(EN) Disclosed is a hydrogen generator with a door that can be opened to replace a fuel unit and closed to seal the door. A lock responds directly to pressure within the chamber to prevent opening when the pressure exceeds a threshold value. The lock includes a locking member with a lug that engages a retainer to seal the door when the door is locked and is disengaged from the retainer when the door is unlocked. An opening mechanism moves the locking member to lock and unlock the door. A movable key is engaged with the opening mechanism and the locking member when the pressure in the chamber is at or below the threshold value and disengaged from one of the opening mechanism and the locking member by an actuator (e.g., a flexible diaphragm) so the door cannot be unlocked and opened when the pressure is above the threshold value.
(FR) L'invention concerne un générateur d'hydrogène présentant une porte qui peut être ouverte pour remplacer une unité de carburant et fermée hermétiquement. Une serrure répond directement à la pression dans la chambre pour empêcher l'ouverture lorsque la pression dépasse une valeur seuil. La serrure comprend un élément de verrouillage doté d'un tenon qui coopère avec un dispositif de retenue pour fermer hermétiquement la porte lorsqu'elle est verrouillée et qui se désolidarise du dispositif de retenue lorsque la porte est déverrouillée. Un mécanisme d'ouverture déplace l'élément de verrouillage pour verrouiller et déverrouiller la porte. Une clef mobile coopère avec le mécanisme d'ouverture et l'élément de verrouillage lorsque la pression dans la chambre est égale ou inférieure à la valeur seuil et se désolidarise de l'un parmi le mécanisme d'ouverture et l'élément de verrouillage par un actionneur (par exemple un diaphragme souple) de manière telle que la porte ne peut pas être déverrouillée et ouverte lorsque la pression est supérieure à la valeur seuil.
