| 摘要 |
The invention relates to a fuel injection valve (1), more particularly, an injection valve for fuel injection systems in internal combustion engines. Said valve comprises a piezoelectric or magnetostrictive actuator (13). Said actuator (13) actuates a valve closing body (3) by means of a valve needle (2) interacting with a valve seat surface (27) to form a sealing seat. A fuel line (8, 10, 11, 12) extends from a fuel admission tube (7) to the sealing seat. The actuator (13) has a tubular shape and encompasses the fuel line (8, 10, 11, 12) at least in certain areas. |
