Abstract
A cam operated valve mechanism for directing the flow in a fluid flow duct to selective alternative outlets. The valve comprises an annular array of segmented elements which are each pivotally mounted to an axially translatable sleeve disposed coaxially within the duct. In a first axial position the sleeve extends across port and starboard alternative flow outlets, and in a second axial position extends downstream thereof. Each valve element comprises a cam follower which engages an axially extending cam track formed in the duct surface. The profile of the cam track is such that translation of the sleeve from its first to second axial position causes each of the valve elements to rotate from a stowed to a deployed position, and thereby obturate the duct.
