    摘要: An electrohydraulically actuatable injection valve includes a control piston which divides an annular conduit from a control chamber disposed between the control piston and an actuator rod. A spring is disposed between the control piston and the actuator rod. The annular conduit also communicates through a control valve with a drain. If the control valve is closed with the injection valve open, the control piston opens a communication between the annular conduit and the control chamber, so that a nozzle needle is pressed onto an associated valve seat and abruptly stops the injection.
