ABSTRACT:
The present invention relates to an injection valve, in particular to the injection valve for a direct injection of fuel into a combustion chamber of an internal combustion engine. The injection valve includes a valve body mounted in a housing, the valve body having a valve opening surrounded by a valve seat. A valve needle is provided with a closing head extending through the valve opening so that the closing head cooperates with the valve seat to snugly fit into valve seat on the injection discharge side. The valve needle is prestressed by a closing spring into a closing position and moved by an actuating mechanism through an actuating element against the force of the closing spring into an open position. To allow the injection valve to open quickly, the actuating element is closely engaged with the valve needle using a spring acting in the direction of the open position.
