Abstract

Es wird eine Hochdruckleitung (23) vorgeschlagen, in die mindestens eine Einschnürung (29) eingearbeitet wurde, um eine Querschnittsverengung in der Hochdruckleitung (23) zu bewirken. Diese Querschnittsverengung hat zur Folge, dass Druckpulsationen sich nicht oder nur in sehr eingeschränktem Umfang in der Hochdruckleitung (23) ausbreiten können.
