What are the technical features of an oil filter?

An oil filter is a type of filter that can remove impurities and gum from the engine, ensuring the cleanliness of the lubricating oil and extending its service life. However, do you know what technical features it has?
Rubber sealing ring: The high-quality oil filter sealing ring is made of special rubber, ensuring 100% no oil leakage and a long service life.

1. Reflux suppression valve: • Reflux suppression valve. When the engine is turned off, • reflux suppressor valve; When the engine ignites again, it immediately generates pressure and supplies oil to lubricate the engine.
2. Filter paper: The coarse filter removes impurities with a particle size of 0.05mm or more from the oil. The coarse filter with a particle size of 0 to 300 removes impurities with a particle size of 0.05mm or more from the oil. Under severe temperature fluctuations, the coarse filter removes impurities with a particle size of 0.05mm or more from the oil, which will affect the filtration flow rate of the oil. The filter paper of high-quality oil filters can filter impurities under drastic temperature changes, ensuring sufficient flow.
3. Relief valve: • Backflow suppression valve. When the external temperature drops to a specific value or the oil filter exceeds its normal service life, • backflow suppression valve, • backflow suppression valve. Nevertheless, impurities in the engine oil can enter the engine, but compared with the losses caused by a lack of oil in the engine, it is much smaller. Therefore, the relief valve is the key to protecting the engine in an emergency
