摘要

A fuel injection device for a combustion engine comprises high pressure pump (10), piston (18), working space (22) connected to a valve pressure space (40) and fuel injection valve (12) comprising two components (28,128). Piston lift opens and closes a connection giving high pressure in a control region (54) and closing the second component (128).
