Abstract

PURPOSE: To prevent the biassed wearing of needle valve by turning needle valve by the force of spring during the vertical movement by pressing push bar on the needle valve of a fuel injection valve by spring.
CONSTITUTION: A fuel injection valve is formed by coupling the nozzle body 1 and the valve body 3 with the cap nut 2. The oil chamber 8, leading to the high- pressure fuel oil path 7 and also to the nozzle 1b at the top and having the valve seat 1a with the needle seat 4 inside, is formed in the inside of the nozzle body 1. Also, the convexity 5a of the push bar 5 is fitted into the concavity 4e formed at the upper end of the push bar 5 and also the spring 6 is arranged on the upper part of the push bar 5. Thus, when the needle valve 4 is moved upwards by oil pressure, the spring 6 is compressed but at the same time the compression force brings about a revolving force in the spring 6, turning the needle valve 4.
