             To ensure smooth lubricating oil flow and prevent impurities from scratching or roughening component surfaces, the oil must be strictly filtered before being delivered to the friction surface. To achieve a satisfactory filtration effect without increasing oil circuit resistance, the coarse filter is typically connected in series with the main oil passage, while the fine filter is connected in parallel with the main oil passage.
