ABSTRACT:
A fuel injector having pressure equalization passages is provided to equalize the pressure differential across an armature in high vapor pressure fuels. At least one through passage is included that extends from a chamber beneath the armature to a chamber atop the armature to prevent differential pressure buildup when the injector is closed. The passages enable communication between the areas above and below the armature to rapidly equalize the pressure acting on the armature as the boiling bubbles burst and the fuel "explodes".
