ABSTRACT:
An electrostrictive actuator which can be used, e.g., in a distributor type fuel injection device of a diesel engine has an electrostrictive actuator for generating an electric charge upon reception of a load and an electric circuit unit connected to the electrostrictive actuator. The electric circuit unit has an electric charge changing means for changing the electric charge of the electrostrictive actuator in the state of generation of electric charge due to a load exerted on the electrostrictive actuator and thereby constricting the electrostrictive actuator, and an electrical charging means for charging the electrostrictive actuator in the state of constriction due to the operation of the electric charge changing means when the load exerted on the electrostrictive actuator is reduced and thereby extending the electrostrictive actuator.
