Fuel injection device

A fuel injection device for injecting fuel into a combustion chamber of an internal combustion engine, the device comprising:

• an end (6) remote from the combustion chamber, which end (6) has at least one electrical connection (33) and at least one return connection (40), the return connection (40) and the electrical connection (33) being integrated into a common connection body (60);
• and
• a housing body (20) coupled to the common connection body (60), the common connection body (60) comprised of plastic material (62), with the end (6) of the fuel injection device (1) remote from the combustion chamber (6) being encapsulated in the common connection body (60), and
• the at least one return connection (40) runs through a support plate (30) which defines a connection on the end (6) of the fuel injection device (1) remote from the combustion chamber, wherein the support plate 30 is disposed in the housing body (20), wherein at least one return duct (40, 41) extends through the support plate (30), wherein a return chamber 24 is disposed axially from the support plate (30) along a direction extending from the support plate (30) toward the combustion chamber, the return chamber (24) disposed axially between the support plate (30) and a magnet actuator (25) such that at all times, the magnet actuator (25) is spaced at all points axially from the support plate (30), and wherein the return chamber (24) disposed entirely in the housing body (20).
