Description

Technical Field

[0001] The utility model relates to the technical field of piston engines, and more specifically to an oil filter seat structure. Background Art

[0002] The lubrication system is an indispensable component of a piston engine. The lubricating oil used in the lubrication system is sucked from the oil pan by the oil pump, reaches a certain pressure, is cooled and filtered, and then is transported to each lubrication node to lubricate, cool, clean, and reduce noise for the moving parts. The lubricating oil then flows back to the oil pan by gravity. At this time, the lubricating oil may contain impurities, which will affect the reliability of the engine and the oil change cycle. In order to solve this problem, a separate fine filter can be added. This fine filter does not directly participate in lubrication, but is only responsible for more fine filtering of the lubricating oil in the oil pan, that is, the lubricating oil goes from the oil pan to the fine filter, and then directly returns to the oil pan after the fine filter. This can improve the cleanliness of the lubricating oil.

[0003] At present, the fine filter and the main filter are installed separately, which is equivalent to the engine having two lubricating oil lines, increasing the complexity of the system. Utility Model Content
