An in-line injection pump for fuel injection systems with controlled injectors for i.c. engines, including a body containing one or more in-line cylinder-and-piston pumping units driven by a shaft with eccentrics and connected through respective intake and delivery valves to inlet and outlet means for the fuel, characterised in that it includes two pumping units (9, 10) and in that the cams (12) of the drive shaft (8) have a double-lobed profile with null accelerations in the delivery phase and constant speed, so as to ensure constant fuel flow rate along the 360° of rotation of the pump.
