Abstract (en)
[origin: DE19939450A1] Disclosed is a fuel-injection device for internal combustion engines, whereby a fuel-injection valve (9) has a push rod (21) actuated by an injection valve member (14). Said push rod delimits a control space (25) which is constantly supplied with high-pressure fuel and which can be discharged via a control valve (43) and a discharge canal (29) into a discharge chamber (32). The control valve (43) has a valve member (42, 421, 422) which is actuated by a piezo system (45) whereby the valve member (42, 421, 422) together with the edge of a seat (40) forms a first sealing seat (41, 411, 522) with a flat seat.
