Abstract
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.
