Fluid coupling

A valve assembly comprising:

• a probe having a first fluid exit;
• a socket for receiving the probe and having a second fluid exit;
• wherein the probe and socket are moveable along a coupling axis to open and close the valve assembly;
• the valve assembly further comprising
• a closing member arranged relative to one or the other of the first and second fluid exits and and adapted to move between an open position and a closed position, wherein in the open position, the closing member does not obstruct said fluid exit and in the closed position, the closing member seals said exit, and
• a securing means is arranged to secure and release the closing member relative to the probe or socket of the other exit;
• characterised in that
• the movement of the securing means is controlled by a cam and follower arrangement, wherein the securing means is connected to a common pivot axis at two spaced pivot locations across the pivot axis, and two arms extend from the two spaced pivot locations to a catch for securing the closing member, the catch extending parallel to the pivot axis and between the two arms, each arm includes a follower for following a cam to control the movement of the catch, and further wherein the closing member is a movable valve member for selectively obstructing one or the other of the first and second fluid exits.
