Abstract
A fuel injection pump of the radial piston distributor injection pump type which includes pump pistons, which during execution of their intake stroke, are acted upon from a side of a pump work chamber with fuel at a first, higher pressure, which is taken from a suction chamber. The pump pistons on their opposite outer face ends are acted upon by a pressure of a lesser magnitude, and this latter pressure is adjusted in a chamber that is divided from the suction chamber by a movable diaphragm. Hence mechanical restoring means for the pump pistons for executing their intake stroke are dispensed with.
