Abstract (en)
[origin: DE10149915A1] The fuel injection valve (1) has a piezoelectric or magnetostrictive actuator (2) for operation of a valve needle and an associated valve closure cooperating with a valve seat. The actuator is enclosed by a compensation sleeve (6) of a material with a small or negative temperature expansion coefficient, radially enclosed by a spring sleeve (17) connecting upper and lower valve body sections (3,13), providing compression of the compensation sleeve.
