摘要

Improvements in the liquid fuel injection and pumping apparatuses, for supplying fuel to internal combustión engines, characterized in that the apparatus comprises a reciprocating pump piston in reciprocation, within a bore, in timed relation with an associated engine, an output from a first end of the bore, said outlet being connected, in service, to a fuel injector associated with a motor cylinder, a fuel supply passage made in the bore near said first end thereof, said step being covered of fuel supply by the plunger when the latter moves towards said first end of the bore, fuel being expelled through the outlet when said passage is covered and during the subsequent movement of the plunger, said plunger being formed by two parts, being provided for elastic means for forcing the plunger parts towards each other and means for admitting under pressure between said parts of the plunger to determine a controlled separation of said parts, so that the moment of movement inward of the plunger in which said step is covered can be varied.
