Claims

[Scope of utility model registration request]

A core for a solenoid having a fuel passage formed therein, a magnetic plunger having a passage aligned with the passage and disposed at the tip of the core via a non-magnetic annular sheet so as to be moved toward and away from the tip with a minute stroke, and the plunger. a fuel storage hole that is to be isolated from the passage when the plunger comes into contact with the tip of the core via the annular seat; is formed on the annular sheet.
