Abstract
The two end members (1, 4) are locked by a self-retractable hook (15) which engages in a groove (23) in the female end member (1). The hook (15) is connected to an actuating lever (11) biased by a spring (14) and provided with a push-button (20). Pivotally mounted on the other arm of the lever (11) is a yoke (6) mounted on the male end member (4). When the transfer has finished, the hook (15) is retracted by depressing the button (20) so as to unlock the coupling. In the event of frosting, by depressing the button (20) still further, the yoke (6) upwardly urges the female member (1) and separates the two end members. Application in the transfer of liquid oxygen from a storage container to a portable container for domestic oxygen treatment.
Claims11
A device for transferring a cryogenic fluid comprising two end members each being a part of a respective container and the end members being cooperative by a simple pushing of one end member into the other end member, a locking element having an active position for locking together the two end members and an unlocking position for releasing the two end members from each other, an element for separating from each other the two end members combined with the locking element so that, when the locking element is in said active position, the separating element is retracted and when the locking element is in said unlocking position the separating element is active for separating the two end members, and a common mechanism for actuating the separating element and the locking element.
A device for transferring a cryogenic fluid from a first container to a second container, the device comprising:
- two mating tubular end members each being a part of a respective container and communicating with an interior space of the respective container, the end members being cooperative for transferring said fluid by a simple pushing of one end member into the other end member;
- a locking element having an active position for locking the two end members in a coupled position and an unlocking position for releasing the two end members from each other;
- a separating element for separating the two end members from each other, the separating element being combined with the locking element so that when the locking element is in said active position, the separating element is in a retracted position and when the locking element is in said unlocking position the separating element is active for separating the two end members from each other;
- and a common mechanism for actuating the separating element and the locking element.
