Self-regulating piston pump, especially injection pump for internal combustión engines in which the piston divides the corresponding cylinder in a pressure chamber and in a regulating chamber and is mechanically driven in the direction that it contracts the compression chamber (forward stroke ) and by a preferably elastic attraction device in the other direction (return stroke), the pressure chamber having a supply conduit and a delivery conduit for the useful expenditure of the pump and the regulating chamber having an inlet conduit and an outlet conduit provided with appropriate means for braking and/or for delaying the passage of the liquid passing through it in such a way that from a predetermined driving speed and as this velocity increases the return stroke and consequently the stroke of subsequent flow are shortened and that the volume of the liquid fed per cycle through the expulsion duct of the compression chamber decreases characterized in that the outlet conduit of the pressure chamber and has appropriate means to prevent the reflux of the liquid from the pressure chamber during the piston return stroke with the inlet duct of the regulating chamber being connected to a source of the liquid to be supplied.
