13DV09910, A fluid supply and synchronizing mechanism are provided for a jet engine exhaust nozzle. The exhaust nozzle has flaps which are moved by flap mounted actuators which move with the flaps. The fluid supply includes a supply tube, a return tube and a strut for each actuator. The two tubes and strut are connected to each actuator for movement with the actuator. The strut prevents flexing of the tubes during movement The synchronizing mechanism interconnects the flaps so that movement of any one flap is transmitted to all other flaps thereby retaining nozzle symmetry.

Why it's free to use
- Filed March 12, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 12, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 12, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
