摘要： A fuel injector, in particular for the direct injection of fuel into the combustion chamber of a mixture-compressing, externally fired internal combustion engine, comprising, upstream from a valve-seat surface, a swirl disk provided with swirl channels from which, given an open fuel injector, the fuel flows with a circumferential speed into a swirl chamber which is also located upstream from the valve-seat surface. Each point downstream from the swirl disk (35) through which a flow is to pass has a larger extension in every spatial direction than the diameter of the swirl channels.

摘要： A fuel injector has a chamber between a valve body and a plate in which a plurality of through holes are formed. The chamber has a diameter larger than that of an opening of the valve body. The through holes are opened at an outer chamber area shaded by the valve body are distanced from an outer wall of the chamber more than a diameter of the through hole. Fuel flowing along an inner inclined surface of the valve body turns to the through holes and flows into the through hole from all directions and collides with each other at inlets of the through hole. Therefore, injected fuel has a lot of turbulences and is finely atomized.

摘要： A fuel injector comprising a nozzle body having a first bore defining first and second seatings, an outer valve needle being slidable within the first bore and engageable with the first seating to control fuel flow from a first outlet opening. The outer valve needle is provided with a second bore within which an inner valve needle is slidable, the inner valve needle being engageable with the second seating to control fuel delivery through a second outlet opening. The outer valve needle includes a deformable region which is shaped such that, in use, when the outer valve needle is urged against the first seating, the outer valve needle deforms. The deformable region may be shaped such that, in use, when the outer valve needle is urged against the first seating, the outer valve needle deforms to close the first outlet opening. Alternatively, or in addition, the deformable region may be shaped such that, in use, when the outer valve needle is urged against the first seating, the outer valve needle cooperates with the inner valve needle to form a substantially fluid tight seal. The fuel injector may further comprise a valve insert member received within an upper region of the second bore, the valve insert member being engageable with an additional seating defined by an open end of the second bore to permit fuel upstream of the inner valve needle to vent from the second bore.

摘要： A method is provided for manufacturing an orifice disk. Metal foils are made available, opening geometries and auxiliary openings are introduced in the metal foils. The individual metal foils are superimposed in centered fashion. The metal foils are joined using a joining method, thus creating an orifice disk band having a plurality of rounds. Finally an isolation of the rounds or orifice disks is performed. The orifice disks manufactured in this manner are particularly suitable for use in fuel injection valves that are utilized in mixture-compressing, spark-ignited internal combustion engines.

摘要： A fuel injector nozzle assembly includes an injector body including a valve seat with a supply passage through which fuel flows generally along a supply axis. The valve seat presents an upper surface which is adapted to engage a valve to seal the supply passage. A nozzle plate is mounted onto the valve seat and includes a plurality of orifice holes therein through which fuel flows. The valve seat further includes a first edge protrusion protruding into the fuel flow for generating a first separation of the fuel flow, thereby creating a plurality of small eddies which are entrained within the fuel flowing adjacent thereto. A turbulence cavity is defined by the nozzle plate and the valve seat wherein fuel flows into the turbulence cavity through the supply passage and out from the turbulence cavity through the plurality of orifice holes.

摘要： A fluid injection nozzle (5) is mounted on a fluid injector valve (1) in order to control the flow of (and atomize) fluid passing through an injection hole (3b) of the fluid injector (1). The fluid injection nozzle (5) may include at least one nozzle hole (5a) that comprises an inlet hole (51a), an intermediate hole (52a) and an outlet hole (53a). These holes preferably serve to impart a step-wise control of the fluid flow exhausted from the injection hole (3b). The intermediate hole (52a) may have a longitudinal axis (L2) that extends substantially perpendicular toward a nozzle axis (L1). The intermediate hole (52a) may include a first terminal end that communicates with the inlet hole (51a) and a second terminal end that communicates with the outlet hole (53a). The intermediate hole (52a) preferably has a substantially uniform width (W) along substantially the entire length in the longitudinal axis (L2). The outlet hole (53a) may have the central axis (L3) that is displaced from the longitudinal axis (L2) of the intermediate hole (52a) by a distance (Y).

摘要： A fuel injection valve has a valve seat element having a fixed valve seat. A valve closure element coacts with the valve seat to open and close the valve. The valve seat element possesses an outer enveloping surface that is equipped with a coating made of a material other than the material of the valve seat element, or with an adhesive, by way of which a hydraulically sealed join can be achieved between the valve seat element and a valve seat support that receives the valve seat element. The fuel injection valve is suitable in particular for use in fuel injection systems of mixture-compressing spark-ignited internal combustion engines.
