Patent number: 11248572Abstract: A fuel distributor, which is in particular used as a fuel distribution rail for mixture-compressing, spark-ignited internal combustion engines, including a base body, at which at least one high-pressure inlet and multiple high-pressure outlets are provided. An insert element is furthermore provided that is situated in an interior of the base body. In the interior, the insert element separates an inflow area, which extends from the high-pressure inlet to the high-pressure outlets, at least essentially from a damping area. The insert element is designed as a thin-walled insert element that forms a divider extending through the interior at least from the high-pressure inlet to the high-pressure outlets.Type: GrantFiled: February 1, 2019Date of Patent: February 15, 2022Assignee: Robert Bosch GmbHInventors: Alexander Schenck Zu Schweinsberg, Klaus Joos, Markus Amler, Michael Bauer
