Abstract (en)
[origin: US4725003A] An electrically actuatable fuel-injection valve for internal combustion engines has a piezoelectric vibrator (1) provided with electrodes (2, 3). A fuel-receiving chamber (4) in the vibrator is in fuel-conducting communication with a fuel feed path (constriction 5) and an ejection opening (outlet opening). The fuel feed path as well as the ejection opening are so shaped that upon the application of a voltage to the electrodes (2, 3) the fuel is imparted a preferred movement (8) through the chamber to the ejection opening.
