Abstract (en)
[origin: EP1577538A1] A damping chamber (50) for outer and inner damping pistons (41,43) is provided to an outer needle nozzle (11) to communicate with a closing chamber (29) via a hydraulic connection. The end face (37) of the outer needle nozzle is exposed to the closing chamber that communicates with a low-pressure return system (35) via a closing chamber throttle (31).
