も異物の除去性は良好になる。In the present invention, the first important characteristic of the combustible river filter is the ability to remove ¥C substances, but this is related to the shape and diameter of the connected micropores in the porous polyamide resin sintered body. 3゜Figure 1 is a cross-sectional photograph taken with a scanning electron microscope of a porous yet polyamide resin sintered body. Since the porous polyamide resin sintered body has an amorphous shape, the micropores in the porous polyamide resin sintered body are considerably larger than the particle size of foreign substances mixed in fuel such as gasoline, and the removal of foreign substances is also good.
第２図に多孔質ポリアミド樹脂焼結体中の微細孔の平均
孔径と異物の除去率の関係を示ザ。Figure 2 shows the relationship between the average pore diameter of micropores in a porous polyamide resin sintered body and the foreign matter removal rate.
試験は一定濃度の異物混入液を一定時間連続濾過した後
、フィルタにより除去された異物の除去率を測定した。In the test, a liquid containing foreign substances at a certain concentration was continuously filtered for a certain period of time, and then the removal rate of foreign substances removed by the filter was measured.

孔径に影響される。Next, regarding the second important water removability, since polyamide resin inherently has a large contact angle with water, the water removability is influenced by the pore size of the micropores on the surface of the porous polyamide resin sintered body. .
第３図に表面の孔径と水分との除去率との関係を示す。FIG. 3 shows the relationship between the surface pore diameter and the water removal rate.

有効多孔率との関係を第４図に示す。In addition, since the pressure drop is related to the diameter and numerical aperture of the micropores in the porous polyamide resin sintered body, the number of fluctuations in the pressure loss is calculated using the effective porosity test method for sintered oil-impregnated alloys (JIS
Z2506), expressed as effective porosity,
The relationship between pressure drop and = 4 - effective porosity is shown in Figure 4.

に使用し得る。Since the filter is constantly subjected to pressure from fuel, its strength was measured as radial crushing strength according to the radial crushing strength test method for sintered oil-impregnated bearings (JIS 72507). As a result, in the case of low viscosity fuel such as gasoline, a porous sintered body made only of polyamide resin with a radial crushing strength of 1.5 kg/cocoon 2 is sufficient for pump discharge pressure cuffs up to about 9/cm2. It's worth it. Also,
When using fuel with relatively high viscosity such as light oil, or when the discharge pressure of the fuel pump exceeds 7 b/cm, inorganic substances (
For example, it is manufactured by adding an appropriate amount of thermosetting resin (epoxy resin, phenol resin, etc.) to polyamide resin and co-bonded with it. Radial crushing strength 2.0Kg
/ Porous polyamide resin sintered body of #2 or more can be used more preferably.
