Abstract

An injection system for an internal combustion engine may include a high-pressure pump for delivering fuel at high pressure into a high-pressure region, wherein the high-pressure pump includes an inlet valve and an electrically switched, digitally actuated outlet valve. The outlet valve is designed as a normally-open outlet valve. In this way, it is possible to dispense with a pressure relief valve for the high-pressure region.
