Abstract: An improved fuel injector for delivering fuel to an internal combustion engine. The fuel injector comprises an injector body. The injector body comprises a first conduit, and an electrical module arranged within the first conduit. The electrical module comprises an actuator and electrical connections. The injector body is disposed within the fuel injector such that a back leak channel form the fuel injector passes through at least a part of the first conduit.

Abstract: The present invention relates to a control valve (113; 113') for a fuel injector (101). The control valve (113; 113') has a control valve body (115; 115') which defines a supply passage (133; 133') for high pressure fuel. A control chamber (119; 119') and a pressure compensating chamber (143; 143') are provided in the control valve (113; 113'). The control chamber (119; 119') and the pressure compensating chamber (143; 143') are both in fluid communication with the supply passage (133; 133'). A control valve member (117; 117') is provided for controlling fuel pressure in the control chamber (119; 119'). The pressure compensating chamber (143; 143') is spaced radially outwardly from the control chamber (119; 119'). The invention also relates to a control valve member (117') having a pressure compensating cavity (159).
