    摘要: A method for producing a throttle point, particularly in a channel of a valve piece of a fuel injector is disclosed. The following are performed: first, the outlet channel is created by machining. Then, the throttle point is stamped by a stamping die inserted into a guide hole. The pre-stamped throttle point is electrical-discharge machined in such a way that said throttle point has an electrical-discharge machined inlet area and comprises a stamped outlet area, which lies before a continuous cross-section expansion of the outlet channel as viewed in the flow direction.

    摘要: A fuel injector assembly comprising an engine camshaft driven piston plunger in a plunger body, a control valve, an electromagnetic actuator for stroking the control valve between limiting positions and a valve stop assembly establishing a first limiting valve stroke position when the control valve is fully open and a second valve stroke position corresponding to a reduced fuel delivery pressure prior to a main fuel pressure pulse in a fuel injection event.

    摘要: Fluid in a chamber, through which a fuel control armature is moving, is used to dampen armature vibrations. This dampening effect is achieved by forming a passage through which the fluid flows as the actuator moves to a steady state position. This passage may be implemented in a control module for controlling fuel delivery in a fuel injector. The control module includes a control module housing defining the cavity. The armature is disposed at least partially within the cavity. The armature affects the flow of fuel in the injector by changing the area of a fuel port through which fuel passes. The fluid passage is formed as the armature moves towards a contact wall defining the cavity.
