Oil filter

Abstract

An oil filter capable of efficiently removing foreign matter, such as carbon, oil sludge and metal powder, and prolonging maintenance timing is provided. The oil filter body (1) integratively has an oil passage (27) for applying a centrifugal force on flowed-in oil, a collecting bag (29) for collecting foreign bodies with a large proportion which is throwed outwards by the centrifugal force, and a magnetic filter (35) mounted at the downstream side of the oil passage (27) and capable of removing metal powders.

Description

technical field [0001] The invention relates to an oil filter with a magnetic filter. Background technique [0002] Lubricating oil is used in automobiles, machinery manufacturing, machining, machine tools, ships and other fields, and the lubricating oil is recycled. [0003] For this reason, an oil filter should be installed in the circulation circuit to filter the oil. Generally speaking, the oil filter plays the role of removing carbon dust generated by incomplete combustion of the engine, paint and sludge generated by high-temperature oxidation, and metal powder generated by wear and tear of the engine, etc. Remove, and supply the oil that has been filtered and become clean to the engine, etc. [0004] Conventionally, it has been proposed to use a magnetic filter that efficiently removes foreign substances mainly metal powder (see Patent Document 1). [0005] [Patent Document 1] JP-A-11-77479 [0006] The existing magnetic filter is a filter that can adsorb metal pow...

AI Technical Summary

Problems solved by technology

[0006] The existing magnetic filter is a filter that can adsorb metal powder on the filter element made of excited metal fiber, and its adsorption and removal efficiency is very high. However, the carbon powder generated in the combustion chamber of the engine cannot be used. Magnetic filter r
