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.

A nozzle plate has a plurality of blades in the area that surrounds the nozzle hole on the outer plane of the bottom wall part. When the fuel is injected from the nozzle hole and the pressure in the vicinity of the nozzle hole is reduced, the plurality of blades guide a flow of air from the radially outward side of the bottom wall part to the radially inward side of the bottom wall part and generates a swirling flow of the air about the center of the bottom wall part. The swirling flow of the air about the center of the bottom wall part changes to a helical flow by receiving kinetic momentum from fine particles of the fuel injected from the nozzle hole and the helical flow of the air transports the fine particles of the fuel.

A valve (or fuel injector), which provides that the valve-seat member exhibits high structural strength and fatigue strength under vibratory stresses, includes an excitable actuator for actuating a valve-closing member which, with a valve-seat face on the valve-seat member, forms a sealing seat, and injection openings which are downstream of the valve-seat face, the injection openings being in a center area of the valve-seat member projecting outwardly dome-like in the injection direction. The dome-like center area has a curved outer contour, the curvature in a radially inner section having a larger radius than the radius of the curvature in a radially outer section of the dome, which ends radially outside the mouth areas of all injection openings, in a recessed depression, that is followed radially outwardly by an axially projecting edge area of the valve-seat member. The fuel injector directly injects fuel into a combustion chamber of an engine.

A fuel injector extends along an injector axis from a proximal side to a distal side. The fuel injector comprises: a solenoid unit comprising a magnetic coil in a solenoid housing, the solenoid unit circumferentially surrounding a distal aperture around the injector axis; a cable element connected to the magnetic coil; a coherent plastic body comprising a solenoid portion molded onto the solenoid unit, a cable portion extending proximal from the solenoid portion and molded over the cable element, and a holder portion that is disposed proximal from the solenoid unit and that circumferentially surrounds a proximal aperture around the injector axis; and an axially extending injector body, which is adapted for guiding fuel from the proximal side to a nozzle at the distal side, which injector body is received in the first and second aperture.

An injector for injecting a fluid. In injector includes a filter for filtering the fluid to be injected. The filter is arranged in a tubular section of the injector. The filter has a sleeve and a filter body. The sleeve holds the filter body in the tubular section. The sleeve has a securing section and a holding section. The securing section is connected to the filter body. The holding section holds the sleeve in the tubular section of the injector. The filter body or parts of the filter body are arranged exclusively within the securing section.

A protector protects a high-pressure fuel pump for an internal combustion engine. A metal collar is insert-molded into a plate-shaped fiber reinforced plastic portion made of a fiber reinforced plastic of the protector. An outer circumferential surface of the collar includes an uneven portion and a smooth surface. The uneven portion includes recesses and projections arranged alternately in a thickness direction of the fiber reinforced plastic portion. The smooth portion includes a smooth surface parallel to the thickness direction of the fiber reinforced plastic portion. The uneven portion and the smooth portion are arranged in the thickness direction on the outer circumferential surface of the collar.

An injector for introducing a fluid includes a main body designed as an insert and including a first tool contact surface for an injection-molding tool and a second tool contact surface for the injection-molding tool; and an injection-molded housing that completely encloses the main body on at least one portion of the main body, the injection-molded housing including at least one first opening that extends linearly towards the main body.
