Abstract: An electrical connector assembly of a fuel injector includes a body with external walls defining an internal volume and an internal wall dividing the connector in a first part adapted to be fixed in a complementary engagement with the body of the injector and, in a second part adapted to receive another electrical connector. The electrical connector assembly also includes at least one electrical terminal extending through the internal wall from an inner extremity protruding in the inner volume of the first part of the body, to an outer extremity protruding in the outer volume of the second part of the body. The outer extremity is shaped to receive in a complementary engagement an electrical terminal of said another electrical connector. The connector assembly is adapted to be in fluid communication with the back leak return conduit of the injector.

Abstract: An injection pump having a pump body provided with an inlet conduit supplying an inlet chamber, and a compression chamber downstream from the inlet chamber under which a piston reciprocates to distribute liquid fluid from the compression chamber to an outlet pipe in communication with a common rail circuitry. The injection pump has a valve provided with a resilient cup, located between the inlet chamber and the compression chamber and actuated by an electromagnetic actuator through a pushing rod wherein operation of the valve allows the piston to suck liquid fluid from the inlet chamber into the compression chamber and feed the common rail circuitry or to push back liquid fluid in said inlet chamber and said inlet conduit, in which the pump comprises a filter provided around the pushing rod and located between the valve and the electromagnetic actuator in the inlet chamber.
