1. An apparatus comprising:

  • an internal flow path having a first flow end and a second flow end;

    a fuel reservoir connected to the first flow end;

    a deformable ring comprising a substantially cylindrical outer surface, a first end and a second end, a circumferential ridge disposed between the first end and the second end encircling the outer surface, and an annular opening that leads from a first opening on the first end to a second opening on the second end, the annular opening comprising an approximately cylindrical region near the first end and a conical region that tapers from the cylindrical region to the second end, the second opening being of smaller diameter than the first hole;

    a movable internal sealing member disposed within the internal flow path proximate to the second opening, the internal sealing member being biased against the second opening by a biasing force to form a liquid-tight internal seal that closes the second opening to block the internal flow path, the internal sealing member breaking the internal seal when a device valve of a separate apparatus contacts and forms an external seal with the conical region and then extends an actuating member through the annular opening to exert an opening force directed substantially opposite to the direction of the biasing force on the internal sealing member.
