Abstract

PURPOSE: To obtain a simple and compact fuel filter capable of easily removing moisture and having no outflow possibility of foreign matter, by mounting a porous membrane comprising a hydrophilic and non-oleophilic polymer material.
CONSTITUTION: A fuel filter 1 is partitioned into a water storage chamber 10 and a fuel chamber 11 by a hydrophilic and non-oleophilic polymer porous membrane 7 comprising cellulose acetate and a vinyl chloride tube is provided to a drain port 9 so as to exert pressure on said port 9 under gravity according to a Torricellian vacuum theory so that the pressure of the water storage tank becomes smaller than that of the fuel chamber 11 and the tube 12 is preliminarily filled with water to hold water in the tube 12 under surface tension at the outlet 12a thereof. Fuel is passed through a filter element 4 from a fuel inlet part 2 not only to remove dust in the fuel but also to grow moisture suspended in the fuel to coarse particles while the sedimented and gathered moisture is selectively absorbed by the porous membrane 7 to be spontaneously flowed in the water storage chamber 10 and excess water is drained breaking the surface tension at the outlet 12a.
