Flow limiter for high pressure screw connection with common-rail-injection system`s sealing surface, has throttle hole arranged at funnel point, where inner and outer surface of funnel corresponds with sealing surface of screw connection

摘要

The limiter has a throttle hole (13) limiting flow arranged at funnel point, where the flow limiter is designed as a funnel and made of a material group. The funnel point of the limiter consists of material characteristics minimizing the abrasion of the limiter. The inner and outer surface of the funnel is designed such that they corresponds with the conical shaped sealing surfaces of a high pressure screw connection. An independent claim is also included for a high pressure screw connection with a flow limiter.
