Definitions
- the invention relates to an arrangement of a fuel pump in a swirl pot Fuel tanks according to the preamble of claim 1 (see DE-A-37 13 276).
- a supply device is known in which a between Fuel pump and manifold used pressure switch depending on the Pump outlet pressure switches between conductive and non-conductive and thereby the Fuel pump via a control circuit with different electrical power is supplied when the pump outlet pressure exceeds or exceeds a threshold value of the pressure switch falls below.
- the invention is therefore based on the object of measures to find with which the fuel pump can be switched on and off without impermissible Heating is achievable.
- the invention is based on the consideration that the consumption of the internal combustion engine adjusted flow rate does not cool the electric motor sufficiently. Against this the inventive features. They ensure adequate cooling of the electric motor.
- the drawing shows a section through an arrangement according to the invention Fuel pump 1 in a swirl pot 2 of a fuel tank 3 of a vehicle internal combustion engine.
- the swirl pot 2 has an upwardly open storage chamber 4, in the central the fuel pump 1 is arranged and via a first pump stage 5 from the Fuel tank 3 sucks fuel through a filter 6 and into the storage chamber 4 promotes. The fuel delivered in excess fills the storage chamber 4 to Overflow 7. A second pump stage 8 sucks fuel out of the storage chamber 4 and promotes this, adapted to the needs of the internal combustion engine, via a line 9 to Internal combustion engine.
- the first pump stage 5 by a Electric motor chamber 10 of the fuel pump 1 in the storage chamber 4 of the Rolling pot 2 promotes so that the electric motor / fuel pump through in excess amount of fuel delivered is cooled.
