Fuel supplying conduit and injector`s threaded connection rotation immobilizing device for e.g. airplane jet engine, has ring with serration cooperating with nut`s serration to immobilize ring and nut, and deformable unit placed on ring

The device has a nut (10) mounted at an end of a fuel supplying conduit (12) and screwed on an end fitting (18) of an injector (14). A cylindrical ring (24) has an inner serration (28) cooperating with an outer serration (30) of the nut to immobilize the rotation of the ring and the nut relative to...

Beschreibung
Zusammenfassung:	The device has a nut (10) mounted at an end of a fuel supplying conduit (12) and screwed on an end fitting (18) of an injector (14). A cylindrical ring (24) has an inner serration (28) cooperating with an outer serration (30) of the nut to immobilize the rotation of the ring and the nut relative to each other. A finger (32) of the ring cooperates with the injector to immobilize the rotation of the ring on the injector. An elastically deformable unit (26) i.e. metallic wire, is mounted on the ring and cooperates with the nut by elastic lock mechanism to axially immobilize the ring on the nut. Dispositif d'immobilisation en rotation d'un raccord vissé, comprenant un écrou (10) monté sur un premier élément et vissable sur un embout fileté (18) d'un second élément, une bague (24) engagée autour de l'écrou et comportant des moyens (28, 32) coopérant avec l'écrou et le second élément pour immobiliser l'écrou et le second élément en rotation l'un par rapport à l'autre, et un organe (26) élastiquement déformable montée sur la bague et coopérant par encliquetage élastique avec l'écrou pour immobiliser la bague axialement sur l'écrou.
