Abstract
An improved, simplified pressure/time dependent fuel injector assembly for injecting fuel intermittently into a combustion chamber of an internal combustion engine. The injector assembly includes a unitary or single-piece injector body which has at least one groove-like channel on the exterior surface thereof. The channel is closed and sealed by a sleeve which is press-fit about that portion of the injector body on which the channel lies. For reciprocation within the injector body, there is provided an injector-plunger assembly which includes a top stop mechanism for adjustably setting the distance traveled by the plunger assembly during the reciprocatory movement thereof.
