Document Type and Number:
Japanese Patent JP4499250
Kind Code:
B2
Abstract:
A fuel injector, especially an injector for fuel-injection systems of internal combustion engines, includes a piezoelectric or magnetostrictive actuator arranged in an actuator space of a valve housing of the fuel injector, the actuator space being sealed from a fuel by a seal. A valve-closure member, which can be actuated by the actuator and interacts with a valve seat to form a sealed seat, assumes the actual valve operation. The seal has a sealing member and a sealing element. The sealing element is joined to the sealing member by a first circumferential welded seam, is elastically deformable and band-shaped, and is joined to the valve housing by a second circumferential welded seam.
