Prevention of waste oil from engine lubrication system and separation of oil impurities from internal combustion engine oil filter when separating oil filter from internal combustion engine

摘要

The present invention relates to the prevention of waste oil inflow of the engine lubrication system and the separation of oil impurities of the internal combustion engine oil filter when the oil filter of the internal combustion engine is separated. In particular, the separation, exchange and engine oil exchange of the oil filter for an internal combustion engine such as an automobile, etc. It prevents contaminated oil remaining in the oil filter from flowing into the engine's lubrication system and oil pump, thereby preventing engine oil from being contaminated, keeping the engine oil clean, and improving the operator's working environment. In order to be able to, the oil filter is provided with a waste oil circulation inflow prevention means, the rubber valve 15 having a resilience that is placed on the support boss 12, and the frame 15a formed around the outer side of the rubber valve 15 And a plurality of cutouts having a thickness smaller than that of the frame 15a and being radially cut at equal intervals from the center of the rubber valve 15 and having sharply cut portions thereof. An inlet pipe 16 for screwing the bar piece 15b and the upper end of the support boss 12 so that its lower circumferential surface is pressed and fixed to the support boss 12 by the frame 15a of the rubber valve 15. And a cover 17 detachably coupled to the upper portion of the suction housing 11 through the inlet pipe 16 and the inlet pipe to closely adjust the cover 17 to the suction housing 11. A screw 18, a nut 18 fixed thereto, an outlet pipe 19 integrally formed on one side of the frying cover 17, and a filter housing 21 provided separately from the suction housing 11 And an outlet pipe 22 formed through the central portion of the filter housing 21, a lower support plate 23 fitted through an upper end of the outlet pipe 22, and a lower support plate fitted through the outlet pipe 22. It is attached between the periphery of the upper support plate 25 and the upper support plate 25 formed at the upper end of the filter net 24 and the filter net 24 and the upper and lower support plates 25 and 23 seated on the (23) It consists of a filter element 27 consisting of a cylindrical filter paper 26 which includes a plurality of blades fitted and radially bent, the upper and lower support plates 25 and 23 and the upper and lower ends of the filter paper 26. A spring 28 having a fine cross-sectional area is elastically interposed between the surfaces to allow the filter paper 26 to vibrate finely, and the buffer rubbers 29 and 30 are attached to upper and lower ends of the spring 28. The filter paper 26 is held between the upper and lower support plates 25 and 23 to absorb the friction noise of the spring 28, and the filter paper 26 passes between the blade and the blade of the filter paper 26. Impurity separation means is configured to form the lower inflow space 31 so that foreign matters and impurities in the oil separated by vibration and foreign matters attached to the filter paper 26 are introduced and collected.
