摘要： Embodiments may provide a fuel injector including a nozzle body having one or more nozzles, each capable of spraying a fuel from a respective spray position, and movable to change the spray position from a first position to a second position. An injector needle may be configured for axial movement relative to the nozzle body from an engaged position, to prevent flow through the one or more nozzles, to a disengaged position. The movement of the one or more nozzles from the first position to the second position and then back to the first position may substantially correspond with, and/or may be substantially be determined by, the relative axial movement between the injector needle and the nozzle body from the engaged position to the disengaged position and then back to the engaged position.

摘要： An injector for a fluid is provided, in particular for fuel, which has a valve housing, an intake nipple for the fluid disposed at one housing end, a nozzle body disposed at the other housing end, which has a valve seat surrounding a spray-discharge orifice, and a valve chamber disposed upstream therefrom, and a fluid-carrying pipe which extends in the valve housing and connects the valve chamber to the intake nipple. To achieve a connection of the fluid-carrying pipe to the valve chamber that is impervious to high operating pressures and is suitable in terms of production and convenient in terms of assembly, an axial blind hole which has an internal thread and is disposed at a radial offset to the housing axis of the valve housing, is formed in the nozzle body, and a fluid connection us established from the blind hole to the valve chamber. At its pipe end facing away from the intake nipple, the fluid-carrying pipe is screw-fitted in the blind hole and the threaded connection is sealed with respect to the blind hole.

摘要： A fuel injector includes a body piece that defines a nozzle supply passage and a chamber in fluid communication therewith and configured to contain a fluid pressure within the fuel injector. The body piece has a threaded segment and a second, unthreaded segment that includes an outer surface of the fuel injector. A tip piece is clamped via a clamping piece to the body piece to form a fluid seal therewith, and a needle check extends within the body piece and the tip piece. The body piece is configured to contain fluid pressures, for example up to and exceeding 200 MPa, and has a wall thickness between the chamber and the unthreaded segment that is linked to a fluid pressure of fuel passing through the chamber. The fuel injector is configured via integrating portions of a nozzle case and a body guide to contain the extremely high fuel pressures.
