摘要： A fuel injection pump, particularly of the distributor type in which a piston is driven with reciprocating and rotary motion in order to effecting a combined action of pumping and distribution to the various cylinders of the internal combustion engine associated therewith, comprising a regulation control unit which receives signals as a function of which the pump throughput is to be varied, and which by means of an actuator correspondingly controls the movement of a delivery control element. Said control element consists of an annular valve traversed by the injection pump piston and axially constrained with respect to the casing of said pump, but able to rotate by means of a helical gear--worm gear device in order, as a function of its angular movement controlled by the actuator, to cause the uncovering, by at least one oblique slot provided on the inner diameter of said valve and emerging at least one flat face thereof, of at least one bore of a plurality of discharge bores present on the outer surface of the piston and connected to the pump pressure chamber. The instant of termination or initiation of the injections is thus determined, together with the quantity of fuel delivered.
