Abstract (en)

[origin: EP1403509A2] The pressure limiting fuel feed (56) for a motor vehicle has the pressure limiting valve in the fuel pump (30) of a fuel injection system. There is a compensating chamber (82) for short term pressure peaks on each feed pass of the fuel pump to prevent unwanted opening of the pressure limiter (35) in normal operation of the fuel injector. The limiter has a piston (72) with a first connection (74) formed as a throttle between the chamber (82) and a high pressure feed passage. Claims include a fuel feed using the pressure limiter.
