Abstract (en)
[origin: WO2022058105A1] The present invention relates to a flow limiter (1) for a fuel injection system, which flow limiter comprises a throttling sleeve (2) with a through-hole (3), a throttle insert (4) which is received movably in the through-hole (3), a sealing portion (5) in the through-hole (3), which sealing portion is a cross-sectional reduction of the through-hole as compared to a first portion of the through-hole in which the throttle insert (4) is arranged, and a spring element (6) which is received in the through-hole (3) and pushes the throttle insert (4) away from the sealing portion (5). The invention is characterised in that the throttle insert (4) has, on its side nearest the sealing portion (5), a sealing surface (10), which closes the through-hole (3) when the sealing surface is in contact with the sealing portion (5). The throttle insert (4) has at least one throttle line (12), which provides a fluidic connection along the through-hole from an inlet opening in the side of the throttle insert (4) furthest from the sealing surface (10) to an outlet opening in the side of the throttle insert (4) closest to the sealing surface (10). The outlet opening is preferably arranged in such a way that the flow exiting from said outlet opening exits within the spring element (6).
