摘要 |
A high pressure unit fuel injector includes a member with a fuel delivery opening to be intermittently supplied with high pressure fuel and a valve seat encircling the fuel delivery opening. A valve cage includes a check-valve chamber adjacent the valve seat. The chamber includes an annular ledge facing the valve seat and an inwardly facing wall surrounding the ledge. A disk is located within the chamber and has opposite first and second faces alternately seatable against the valve seat and the ledge respectively. The disk has a plurality of openings between the first and second faces and a circular-shaped groove formed in the first face about a center of the disk. The groove intersects the plurality of openings.
