Abstract
PURPOSE:To surely keep excellent fuel injection control with reduced driving power consumption by detecting pressure in a pressure chamber through a pressure sensor partially using a laminated body of a piezoelectric element. CONSTITUTION:A fuel injection valve body 20 is equipped with a driving gear 40 to drive a hydraulic piston 38. The driving gear 40 is composed of a casing 41 and a piezoelectric element 42, and a laminated body of the piezoelectric element 42 is divided into a piezoelectric element group 42c used as a driving means for a piston 38 and a piezoelectric element group 42b used as a pressure sensor with an insulating plate 42a. Pressure in a control rod pressure chamber 36 is transmitted to the piezoelectric element group 42b through the piston 38 and the piezoelectric element group 42c for its detection, and driving voltage applied to the piezoelectric element group 42c can be controlled on the above- mentioned detection signal.
