Abstract (en)
[origin: EP0703363A2] A fuel injection device comprises a body (10), a needle valve (21) axially slidably received in the body, a nozzle spring (22) for biasing the needle valve (21) toward a valve seat (18), and a detection assembly for detecting a time point for lifting the needle valve, that is, a fuel injection time. The detection assembly and the nozzle spring are received in a spring receiving hole (15). The detection assembly has an earth plate (31), a piezoelectric device (32) and an electrode plate (33) arranged in order toward the valve seat. A conical receiving surface (15a) is formed on an upper end of the spring receiving hole (15). The earth plate has an abutment surface (31a) which can be brought into surface contact with the receiving surface. <IMAGE>
