Abstract (en)
A fuel injector has a valve group formed by a pintle (16) and seat (14). The valve group is biased shut by a spring (18). In order to prevent the closing force and speed varying with the hydraulic effects of fuel pressure in the injector, fuel is passed via a bypass (26) to a location between the seat (14) and a seal (24) which is dimensioned to provide a cancelling hydraulic force. Other embodiments use auxiliary springs to give a cancelling force. <IMAGE>
