| 发明名称 | Nozzle tip assembly with secondary retention device | ||
| 摘要 | A nozzle tip assembly and method characterized by the use of a retention device including at least one tab that cooperates with a ledge for coupling a nozzle shroud to a nozzle adaptor. The retention device can be used as a secondary retention feature to prevent nozzle separation and/or to enable the fuel injector to be repaired without having to replace the entire assembly. The latter advantage is of particular benefit when there is damage during assembly or when the nozzle tip assembly is being overhauled. | ||
