Claims

[Scope of utility model registration request]

When a valve opening force due to the high pressure fuel in the liquid reservoir chamber is applied to the needle valve in the nozzle base frame, which is greater than the valve closing force due to the pressure spring, the above-mentioned effect occurs in an injection nozzle that injects fuel from the nozzle at the tip of the nozzle base frame. A control cam that rotates away from the needle valve centerline is pivotally mounted within the nozzle base frame, and the control cam forms a pair of squeezing surfaces that are pinched by a pressure spring and the needle valve. An injection nozzle characterized by interlocking a pressure spring and a needle valve through rotational movement.
