摘要： PROBLEM TO BE SOLVED: To prevent dust having a comparatively large specific gravity from being sucked in through a cutout window even if the cutout window is formed in a cleaner cover externally put on an oil pan.
SOLUTION: A level display surface 23a from which the oil level can be visually confirmed is formed on the side 23 of the oil pan 3, and the cutout window 22a for exposing the level display surface 23a is formed on the cover side surface part 22 of the cleaner cover 4 externally put on the oil cover 3 from above. An intake passage 24 is formed between the oil pan 3 and the cleaner cover 4, and the intake air is sucked from the opening lower end side of the cleaner cover 4 and raised to be guided to the upper end side of the oil pan 3. At that time, right and left ribs 22b, 22c formed on the cleaner cover 4 partition between both right and left edge parts of the cutout window 22a and the right and left raised surfaces 23b, 23c of the level display surface 23a, and the upper end edge of the level display surface 23a is brought into sliding contact with the inner surface of the cleaner cover 4 to be partitioned so that dust having comparatively large specific gravity can be inhibited from being sucked from the peripheral edge of the cutout window 22a.

摘要： PROBLEM TO BE SOLVED: To provide a filter element having high cleaning efficiency for carbon dust and holding ability for dust. SOLUTION: This filter element comprises a first filter material 10 impregnated with no oil and a second filter material 20 disposed at the downstream of the first filter material 10 and impregnated with oil. The filter material 10 is equipped with a wet layer 12 at the downstream for impregnating oil which moves by contact with the second filter material 20 and a dry layer 11 at the upstream preventing impregnation of oil. The density of the first filter material 10 may be smaller than the density of the filter constituting the second filter material 20. The density of the first filter material 10 may be continuously or stepwise small from the upstream toward the downstream. The second filter material 20 may be formed into a suitable shape, such as a pleated shape. The filter material constituting the first filter material 10 and the second filter material 20 may be composed of at least one kind selected from a filter paper and a nonwoven fabric, respectively.

摘要： PROBLEM TO BE SOLVED: To obtain anti-oxidation effect in oil without blending a substantial amount of antioxidant in oil by providing an oil-contact member which contains antioxidant. SOLUTION: A casing of an oil filter 1 for an internal combustion engine is cylindrical with a bottom, and composed of a metal filter case 3, a metal bottom plate 4, and a metal stiffener 5. These members can be oxidation-proof in oil by forming a plated layer containing peroxide decomposer for example over oil-contact portions. Further, an element 6 housed in the filter case 3 comprising a filter material 7, support plates 8, 9, and a metal holder 10, can also be oxidation-proof in oil. In that case, the filter material 7 contains, in a binder thereof, free radical retardant of phenolic derivatives, the support plates 8, 9 are formed with resin which contains free radical retardant by itself, and the metal holder has a plated layer containing peroxide decomposer for example.

摘要： PURPOSE: To smooth the reversion of an intake air in the oil chamber of an oil bath type air cleaner, and minimize ventilation resistance. CONSTITUTION: An oil chamber 3 is provided on the lower part of an air cleaner 1, and a rippling preventing porous plate 10 is horizontally arranged closer to the upper part of the oil chamber 3 so as to be opposed from under to the suction outlet 5 of an inflow pipe 2, and the rippling preventing porous plate 10 is curved more as it gets close to an outer diameter part 10a toward a filter element 6 in the upper part. The intake air flowing down in the inlet pipe 2 is smoothly guided from the center part of the curved porous plate 10 to the outer diameter part 10a, and reaches the filter element 6 in the upper part. Since the intake air is therefore smoothly reversed in the oil chamber 3 and carried from the inflow pipe 2 to a purifying chamber 7, the ventilation resistance in the oil chamber 3 is minimized.
