Abstract
An improved fuel injector for an internal combustion engine with structure which produces a counterforce on the injector valve subsequent to valve closing to inhibit substantial rebound movement of the valve away form its seating surface as caused by the impact of valve closing accompanied by elastic deformation of a valve and its seating surface. The counterforce is generated by creation of a reduced fluid pressure between closely spaced and parallel surfaces, one on the movable valve and the other on the stationary valve guide.
