The invention relates to a unit injector system for supplying the combustion chamber of a self-igniting internal combustion engine with fuel. The unit injector system has a high-pressure chamber that can be subjected to pressure via a pump piston. A storage piston is received inside a storage chamber and is acted upon via a compression spring disposed in a spring holder. A return flow throttle element, which delays the buildup of pressure in the storage chamber, is disposed between the high pressure chamber and the storage chamber of the storage piston.
