Summary:The valve has a valve housing (11) and a valve seat carrier (12) that is projected from the valve housing and fixed in the valve housing. A screwed ring (23) is provided on the valve seat carrier and screwed in an internal thread (111), where the seat carrier includes an external thread (231). The internal thread is formed in the valve housing, and the screwed ring supports an axial stop (24) formed at the valve seat carrier in screwing position. A seal cord is enclosed between the external thread and internal thread, where the sealing cord is made of Teflon(RTM: PTFE). Es wird ein Einspritzventil für ein Fluid, insbesondere für Kraftstoff, angegeben, das ein Ventilgehäuse (11) und einen aus dem Ventilgehäuse (11) vorstehenden, im Ventilgehäuse (11) festgelegten Ventilsitzträger (12) aufweist. Zur Herstellung einer festen Verbindung zwischen Ventilsitzträger (12) und Ventilgehäuse (11), die hohe Axialkräfte aufzunehmen vermag, sitzt auf dem Ventilsitzträger (12) ein Schraubring (23), der mit einem Außengewinde (231) in ein im Ventilgehäuse (11) ausgebildetes Innengewinde (111) eingeschraubt ist und sich in Einschraubendstellung an einem am Ventilsitzträger (12) ausgebildeten Axialanschlag (24) abstützt.
