ABSTRACT:
A multi-chamber oil boom includes a first bladder and a second bladder, each having an inflatable interior. A valve includes an air passage that communicates between the interior of the first bladder and the interior of the second bladder. The valve further includes a clamping spring assembly that provides compressive force on the air passage and closes the air passage until partial inflation of the first bladder causes the air passage to open against the compressive force of the clamping spring assembly to open the air passage and allow air to travel from the inflatable interior of the first bladder to the inflatable interior of the second bladder.
