Injection valve having a perforated disc or atomizing disc and disc or atomizing disc with holes

(57) Abstract: The present invention according perforated disc has a full penetration portion for fluid, the penetrating portion, the inflow opening (40) and the outflow opening (42), located therebetween by being made from at least one passageway (cavity) (41) which have been characterized. At least three functional plane of each characteristic opening structure (40, 41, 42, 43) perforated disc having a (23) (45, 46, 47) is a metal deposited by metal plating (multilayer electroplating) is configured to be positioned on top of the other with, thus perforated disc (23) is an integral. The lower functional plane (45), and a gas supply opening (43) is provided, the gas through the gas supply opening, can be supplied toward the fluid injected, fine results fluid it is possible to atomize the. Outflow opening (42) is part of the gas supply opening (43). Such perforated disc (23) is particularly suited for use in injection valves for mixture-compressing spark-ignition internal combustion engine.
