| description | A fuel injector (10, fig.1) for delivering gaseous fuel to an internal combustion engine, the fuel injector (10) comprising a valve needle (30, fig.1) which is engageable with a valve needle seat (20, fig.1) to control fuel delivery; and an actuator (32, fig.1) for causing the needle to disengage with the seat. A damping arrangement 74 comprises a damping chamber 80 filled with a damping fluid which damps opening movement of the valve needle (30) as it moves away from its seat and further comprising a damping valve 88 which is co-operable with a damping valve seat 90 to control the exit of fluid from the damping chamber 80 to a low pressure drain. The damping valve 88 being configured to disengage from the damping valve seat 90 in response to movement of the valve needle (30) and engagement of the needle with the valve. |
