INJECTOR FOR A COMBUSTION ENGINE

摘要

An injector (30) for a combustion engine comprises a pole piece (3), an armature (5), a valve needle (7) and a guiding element (9) with a guiding portion (11) which is in sliding contact with the pole piece (3). Respective penetrating openings (13, 19) of the pole piece (3) and the guiding element (9) provide a fluid channel for the fluid along a longitudinal axis (L) of the injector (30). The valve needle (7) is arranged axially moveable along the longitudinal axis (L) to prevent or enable a fluid flow. The guiding element (9) is releasably coupled to the valve needle (7) to realize a guidance of the valve needle (7) along the longitudinal axis (L).
