摘要:
An electromagnetic fuel injection valve prevents fuel bubbles from staying at a downstream side of the valve's stopper plate and helps to inject fuel smoothly. The electromagnetic injection valve includes a needle having a valve head opening and closing a valve seat, an electromagnetic coil portion for actuating the needle electromagnetically and a contact portion disposed at the downstream side of the stopper plate on the needle. The stopper plate includes a notch accommodating the needle therein and bubble discharge surfaces made outwardly from the notch to discharge bubbles produced at the downstream side of the contact portion toward the upstream side thereof and help the fuel flow smoothly.
