Abstract

A fuel injection pump, for internal combustion engines, comprising a fixed body and a distributor driven in rotation inside said body by a coaxial shaft, in turn driven by the engine powered by the pump, the pump comprising in addition at least one pumping piston arranged so that it can run in a transversal bore carried by one of the elements consisting of the fixed body and the drive shaft, under the action of a cam carried by the other element, the body being fixed provided with distribution channels - that lead to the injectors and that cooperate with distribution steps carried by the distributor and that communicate with said bore, the pump finally comprising a regulating member that is actuated by a regulator sensitive to the speed of the shaft drive, which is coaxial to this tree and which is capable of periodically opening and closing discharge holes made on the first of said elements entos, which does not serve to transmit the efforts of the pump itself, in such a way, by the same regulator, that this organ is first angularly displaced in relation to the second of said elements so as to vary the advance to the injection and then it is displaced axially so that the unit cost of the pump is varied, as the speed of the pump increases, characterized in that the or - the pumping pistons, are mounted on a transverse bore carried by a solidary assembly formed by the drive shaft and the distributor and are driven by a stationary cam and the regulating member is made up of a stationary ring that cooperates with the discharge holes made on said assembly.
