Förbränningsmotormaskins bränsleinmatningsanordning

摘要

The system has a permanent high-pressure fuel line staying under high pressure for connecting a pump device with a pressure accumulator system. A casing has an insulation thickness that withstands a defined emergency operating pressure in case of conduction failure of the high-pressure fuel line. A region of the system maintaining the emergency operating pressure through the casing is separated from a low pressure region of the system by a check valve (10). Opening pressure of the check valve corresponds to the emergency operating pressure.
