Abstract

Alternative self-regulating pump for fuel injection in internal combustion engines characterized in that it has two alternative regulating organs hydraulically displaced and against an antagonistic force in the direction of ity during the drive stroke of the pump piston that is drawn by the engine on which the pump is mounted so that it performs alternate strokes of constant length whose number is proportional to that of the revolutions of said motor in the time unit, while each of these two regulating members is subject to a preferably braking effect of hydraulic nature during its return displacement so that from a certain speed that is determined for each of these organs by the braking effect and the antagonistic force to which the return stroke of these organs is subjected, it suffers a shortening due to the intervention of the phenomenon called "liquid stop" det At least one of said regulating organs eliminating the beginning of the effective supply of the pump and therefore the injection advance while the other organ acting as engine speed regulator reduces even the amount of fuel supplied by the pump from a speed of determined drag of this one.
