Claims (1)
弁を駆動して針弁の背後にかかつていた油圧を急
速に低下させて上記蓄圧された燃料油をノズルか
ら噴射する蓄圧形電子制御ユニツトインジエクタ
において、上記電磁スプール弁のスプールが摺動
する円周溝に排油路に連通するスリツトを設けた
ことを特徴とするユニツトインジエクタ。 A pressure accumulation type electronic control unit that accumulates fuel oil in a needle valve chamber, drives an electromagnetic spool valve to rapidly reduce the oil pressure accumulated behind the needle valve, and injects the accumulated fuel oil from a nozzle. A unit injector characterized in that a slit communicating with an oil drain path is provided in the circumferential groove in which the spool of the electromagnetic spool valve slides.
