Abstract (en)
[origin: EP0830926A2] The container has two ends of a cross-member (15), the length of which corresponds at least to the diameter of the flexible pipe (8) connected to the container's outlet (4), is suspended on the container by links (14), cables or chains. Extension springs (19) are connected to both ends of the cross-member, with the other ends of the springs fixed on a support frame (6). The extension springs are stretched if the cross-member is located to the side of the outlet in its position releasing the flexible pipe or its flow passage.
