Injection valve for e.g. diesel engine of vehicle, has valve needle guiding device with lower electrical contact pin coupled with upper electrical contact pin over prestressed compression spring for transmission of signals to control unit

摘要

The valve has an electrically insulated valve needle guiding device with a lower electrical contact pin (9) to receive electrical signals generated by an electrical circuit. The pin (9) is electrically coupled with an outward guided upper electrical contact pin (14) over a prestressed compression spring for insulated outward transmission of the generated signals to an external central control unit which is connected with the pin (14).
