Fuel supply device e.g. for supplying internal combustion engine with fuel, has electrically driven fuel pump which delivers fuel from fuel reservoir via fuel filter to internal combustion engine

摘要

The fuel supply device has an electrically driven fuel pump (15) which delivers fuel from a fuel reservoir (11) via a fuel filter (21) to the internal combustion engine, and a pressure limiting device (22). The stop pressure of the fuel supply device is freely adjusted if a second pressure limiting device (24) is provided whose reference connection (25) influencing the opening pressure is impinged upon by pressure from a flow line (26), mounted upstream of a non-return valve (20).
