Abstract
Orifice elements for use in valves for injecting fuel or a fuel-gas mixture. The orifice elements include two silicon plates, joined to one another. An upper plate has one or more injection orifices. The lower plate has a through hole introduced in it, through which a fuel jet can emerge. The lower plate follows in the downstream direction and includes a jet splitter. The jet splitter divides the through hole into at least two passthrough openings so that a dual-jet characteristic is produced or maintained for the valve. At least two conduits are formed between the upper plate and the lower plate. Gas is provided via the conduits and is mixed with the fuel discharged through the injection orifice. The injection orifice and the valve are particularly suited for injection systems of mixture-compressing internal-combustion engines having externally supplied ignition.
