Patent ID: 7347385

Claim:
A fuel injection device for internal combustion engines, comprising, a control chamber ( 2 ), a control valve ( 6 ) having first, second and third valve positions, the control valve ( 6 ) being located between a high-pressure side ( 5 ) and a low-pressure side ( 7 ) and being operable to open or block the communication of the control chamber ( 2 ) with the low-pressure side ( 7 ), an outlet throttle ( 8 ) located between the control valve ( 6 ) and the low-pressure side ( 7 ), and means ( 13 ) moving the control valve ( 6 ) between its first, second and third positions the control valve ( 6 ) blocking the communication of the control chamber ( 2 ) with the low-pressure side ( 7 ) in its first position, the control chamber ( 2 ) communicating with the low-pressure side ( 7 ) via a first outlet conduit ( 14 ) when the control valve ( 6 ) is in its second position, and the control chamber ( 2 ) communicating with the low-pressure side ( 7 ) via a second outlet conduit ( 16 ) providing a second, alternative flow path from the control chamber ( 2 ) to the low-pressure side ( 7 ) when the control valve ( 6 ) is in its third position, said second outlet conduit ( 16 ) having an outlet throttle ( 15 ).
