Abstract

A high-pressure fuel pump includes an outlet valve, a valve ball, a valve spring that acts on the valve ball in a closing direction, and a stop body for the valve ball. The stop body has a stop section that limits the opening stroke of the valve ball, and the valve spring is supported by the stop body. The stop body has a cut-out section that at least partially accommodates the valve spring and that has a radial inner periphery which forms a guide for the valve spring.
