Clogging device of oil pump strainer

摘要

An object of the present invention is to remove the foreign matter attached to the oil pump strainer when the supply pressure is lowered by a large amount of foreign matter in the oil pump strainer to remove the foreign matter from the oil that is accommodated in the oil pan to store the engine oil to pump the smooth oil An object of the present invention is to provide an apparatus for eliminating clogging of an oil pump strainer that is intended to be supplied. The present invention for achieving the above object is an oil pan (1) for storing oil;;An oil pump (3) for pumping oil in the oil pan (1) to supply the respective moving parts of the engine;;An oil pump strainer (2) provided in the oil pan (1) for primarily filtering the oil pumped from the oil pump (3);;A pressure measuring sensor (9) for measuring oil pressure in a supply line (4) connecting the oil pump strainer (2) and the oil pump (3);;A bidirectional drive motor 7 for driving the oil pump 3 forward and backward;;When the pressure measured from the pressure measuring sensor 9 is detected below the reference supply pressure;And an electronic controller (8) for controlling the bidirectional drive motor (7) to reverse rotation so that the oil supplied to the engine flows back to the oil pan (1) through the oil pump strainer (2). Characterized in that the configuration.
