Abstract
Various embodiments include a high-pressure port for a fuel pump comprising: a body defining an internal volume; an outlet valve with an element opening in a first direction; a pressure-limiting valve with an element opening in an opposite second direction; a common valve plate including a sealing seat for both valve elements; and a sleeve guiding the outlet valve element during movement, fastened in the body with an axial stop limiting movement of the outlet valve element and a radial guide guiding the outlet valve element during movement. The guiding sleeve comprises a harder material than the body.
