Abstract
The invention includes a very fast voice coil actuator, in the range of 2-5 millisecond full stroke response with high force, a circuit board located in the enclosure, a pressure sensor sensing pressure internal to the system which in the preferred embodiment is located in the actuator cap assembly but could be located in other locations, a diaphragm, a link plate, a mating ring, and a mechanical pressure regulator. An electronic pressure regulator receives pressure commands from the engine control module in a manner similar to receiving pulse width from an engine control module to an injector and calculates the required new pressure command. A novel feature of the present invention includes the Delta P control and the control of the regulator based on direct feedback of pressure.
