Abstract (en)
A high-pressure pipe has first (3.1) and second (3.2) sections that interconnect in parallel. A choke fits in the second section and connects in series to a non-return valve in the second section. The non-return valve allows fuel to flow out from the second section. The first section has an open end and the second section has a closed end (9). An independent claim is also included for a fuel injection system for an internal combustion engine with a common rail and an injector.
