Abstract
A fuel injector uses two or more individual piezoelectric devices. A first piezoelectric device is used to actuate a valve which allows pressurized fuel to pass from a pressure chamber through an outlet port. The fuel is pressurized by a second piezoelectric device. In certain applications, a return piezoelectric device is arranged in opposing configuration to the first piezoelectric device so that the valve can be positively moved both into its opened and closed positions rather than depending on the return force of a spring.
