4. Structure of centrifugal fine filter: The hollow rotating shaft is fixed on the housing, and the rotor body and the end sleeve are connected together. It is located on the thrust bearing and can rotate freely around the rotor shaft. The compression nut fastens the rotor cover to the rotor body and compresses it with a spring to limit the axial movement of the rotor, with two opposite nozzles installed below the rotor. When the engine is running, a small part of the oil is pumped from the engine oil pump into the filter through the oil port. When the oil pressure is lower than 9s kpa, the inlet pressure limit valve is closed and the fine filter does not work. When the oil pressure exceeds 98 kpa and the pressure limiting valve gradually opens, the oil is ejected from the oil outlet hole through the central hole of the rotor shaft. It then enters the tumbler through the oil hole and is ejected from both nozzles, where the jet reaction forces propel the hand around. When the oil pressure rises to 294 kpa, the rotor speed can reach more than 5000r/min. The proportion of impurities in the lubricating oil in the rotor cavity is larger than that of the lubricating oil. Under the action of rotating centrifugal force, the rotor is thrown to the wall and attached to the wall. The clean lubricating oil at the center enters the two nozzles from the center and continuously squirts out, and the lubricating oil gushing flows back to the lower crankcase.
