Abstract

Liquid fuel injection pump of the kind comprising an oscillating pump piston, a cylinder in which the piston is slidable, said piston extending from the end of the bore and through which the fuel is displaced during a piston stroke of the piston with a pair of orifices formed in the end wall of the cylinder and which are covered during the initial part of the pumping stroke by the pneumatic ribs formed in the plunger and which during the pumping stroke cooperate with one of said pair of holes to terminate the flow of fuel through the outlet communicating said pair of orifices with a fuel supply channel, the fuel of said channel inside said hole through the pair of orifices when the plunger discovers said orifices and means of passage through which the fuel is directed to through at least a portion of said other hole in the face portion of the plunger this other hole closes to move all cavities in the hole to the feed channel.
