ABSTRACT:
A cryogenic fluid flow control system. This cryogenic fluid flow control system utilizes a first element forming a fluid inlet channel and an outlet passage that can be selectively blocked off by a second element that can move relative to the first element by an effect due to the difference in expansion coefficients between the materials of the first and second elements. The outlet passage utilizes a part extending transversely relative to the inlet channel and emerging on the periphery of an end part of the first element, the second element being placed at least partly around said end part.
