ABSTRACT:
Methods and apparatus for controlling a fluid passage provide at least one sliding gate movable transversely to that fluid passage. The fluid passage or the gate is maintained open in a first position of the gate, and is closed in a second position of that gate. A detent detains the gate in one of its first and second positions against a bias acting continuously on that gate. Upon release from that detent, the gate slides by virtue of its bias to the other of its first and second positions. The gate and fluid passage may be incorporated in a frangible connection and the gate may be released from its detent for automatic closure by its bias upon breakage of that frangible connection. Alternatively, the gate may be provided with a slanted surface which abuts another slanted surface around the fluid passage in the first position of the gate.
