Abstract
A high-pressure fuel pump for a fuel delivery system of an internal combustion engine includes a pressure limiting valve positioned between an outlet and an inlet of the pump. The valve includes a spring-loaded closing element and a closing body that radially holds the closing element in place, and that has a concave receiving portion configured to at least partially receive the closing element. The receiving portion has a radially outer first area with a first opening angle, and a radially inner second area with a second opening angle larger than the first opening angle. The first area and the second area are located outside of a contact region between the closing element and the closing body.
