Abstract
The present disclosure relates to fluid injection and the teachings thereof may be embodied in an injector. Some embodiments include an injector comprising: a valve with a valve body and a valve needle; an armature mechanically coupled to the valve needle for moving the valve needle away from a closing position; and a damping element. The valve needle moves in the valve body and seals the valve. The armature displaces the valve needle away from the closing position. The damping element comprises: a hydraulic chamber and a piston arranged to modify a fluid volume of the hydraulic chamber. The piston reduces the fluid volume of the hydraulic chamber when the valve needle moves away from the closing position. A flow restricting orifice hydraulically connects the hydraulic chamber to the cavity.
