Abstract
A fuel injector for an internal combustion engine having a combustion chamber provided with a pressure outlet bore and an unalined fuel inlet bore and which is characterized by a high pressure injecting mechanism at the junction of the chamber with the fuel inlet bore adapted to be positively driven by a fixed-length motion transmission linkage which, in turn, is responsive to pressures above predetermined amounts in said inlet bore. Specifically, the linkage is composed of a plunger reciprocably mounted in the outlet bore, a second plunger serving as a pump piston and reciprocably mounted in the fuel inlet bore, and a rocker arm interconnecting the plungers. The inlet bore is capped by an atomizing nozzle disposed in the upper portion of the combustion chamber. The injector is further characterized by means for varying the predetermined pressures to which the linkage responds.
