Abstract:
A high-pressure fuel injection valve may include a control valve having an actuator, a high-pressure fuel connection and a low-pressure fuel connection. A control plunger and nozzle needle are aligned longitudinally in the valve stem and the valve tip. Together with the control plunger, the receiving chamber of the control plunger forms a closing control chamber delimited by the upper control plunger surface, and an opening control chamber delimited by the lower control plunger surface. Each control chamber is hydraulically connected via a feed throttle to the high-pressure fuel connection and via a return throttle to the low-pressure fuel connection. The control valve opens and closes the fuel return between the return throttles and the low-pressure fuel connection depending on the operation. The flow values of the feed throttles and of the return throttles are selected such that the high-pressure fuel injection valve opens and closes based on actuation of the control valve.
