Structural principle of oil filter

The filter is used to filter out fine particles of impurities, gum and moisture in the oil. Because of its large flow resistance, it is mostly connected in parallel with the main oil passage, and the filtered oil enters the oil pan. One of the commonly used ones is the corrugated microporous paper (or sawn filter) filter. It generally consists of a filter housing, an outer casing and a cover, which are connected by a central bolt. The upper part of the casing has an oil inlet pipe, and the bottom has an oil outlet pipe and an oil drain plug. There is a small oil hole at the upper end of the center tube in the shell. The filter element is sleeved on the center tube, and there is a spring for pressing and positioning. In order to prevent the unfiltered oil from flowing into the filter element from between the splint and the central hole, an oil seal is installed on the center hole of the upper and lower splints.

When the engine is working, the oil in the shunt part flows into the oil filter from the oil inlet pipe, passes through the filter element gap, and the dirt in the oil is blocked (filtered). The filtered oil enters the pipe from the small oil hole in the center pipe, and returns to the oil pan through the oil outlet pipe.
