Double-needle injection-valve

机译:双针喷射阀

摘要

An injection valve arrangement for a high-pressure injection of liquid fuel into a working chamber of an internal combustion engine with the arrangement including at least one valve needle which is urged by a spring force in a closing direction so that a pair of sealing cones associated with the valve needles are brought into engagement with a pair of separate valve seats. The valve needle is liftable in a direction opposite a flow direction effective in the injection process by hydraulic pressure of the fuel to be injected. Pressure chambers having a diameter larger than the respective valve seats are provided and communicate by way of appropriate ducts which merge to form a common flow cross-section. At least two separate line connectors are provided for receiving separate fuels and/or fuel components with the line connectors directing the fuels and/or fuel components to the respective pressure chambers.
