Diesel fuel filter cartridge for e.g. passenger car, has coarse filter unit with large filter pores arranged upstream of fine mesh filter unit, where water contained in fuel flows via pores and coarse dust particles are retained in pores

摘要

The filter has a fine mesh filter unit (28) with small filter pores, such that the dust particles retain in the pores while the fuel flows through the pores. A coarse filter unit (30) with large filter pores is arranged upstream of the filter units in the flow direction of fuel. The water contained in the fuel flows through the pores of the coarse filter unit while the coarse dust particles are retained in the pores.
