Vortex type engine oil filter

Abstract

The invention discloses a vortex type engine oil filter which comprises a filter casing, a filter element, a dust collector, a bypass valve, an oil inlet pipe, a first oil outlet pipe and a second oil outlet pipe, wherein the filter element is in a shape like a cylinder of which one end is provided with an opening; one end, at which the opening is formed, of the filter element is arranged on a top plate of the filter casing; the space in the filter casing is divided into a first cavity and a second cavity by the filter element; one end of the oil inlet pipe penetrates through the top plate of the filter and extends into the second cavity; an arc structure is arranged at the end of the oil inlet pipe, and the outlet direction of the end leads to the circumferential direction of the filter casing; the first oil outlet pipe communicates with the first cavity; the second oil outlet pipe communicates with the second cavity; the dust collector comprises a dust collecting box, a dust deflecting board and support rods; a dust collecting inlet is formed in one end of the dust collecting box; one end, away from the top plate, of the filter casing, is arranged at the dust collecting inlet; a plurality of support rods are arranged at the bottom of the dust collecting box; the dust deflecting board is arranged on the support rods; and the inner space of the dust collecting box communicates with the second cavity through a clearance. According to the vortex type engine oil filter disclosed by the invention, filtering pressure of the filter element can be reduced, and the service life of the filter element can be prolonged.

Description

technical field [0001] The invention relates to the technical field of oil filters, in particular to a vortex type oil filter. Background technique [0002] During the working process of the engine, metal wear debris, dust, carbon deposits and colloidal deposits oxidized at high temperatures, water, etc. are continuously mixed into the lubricating oil. The function of the oil filter is to filter out these mechanical impurities and colloids to keep the lubricating oil clean and extend its service life. [0003] After the oil filter works for a period of time, it is easy to cause clogging. In order to prevent the engine from being damaged due to lack of oil lubrication, the oil filter in the prior art is provided with a bypass valve to ensure that the oil is blocked when the filter element is blocked. Open the bypass valve to supply unfiltered oil to the engine, thereby reducing engine damage. However, unfiltered engine oil contains impurities such as metal shavings, and imp...

AI Technical Summary

Problems solved by technology

However, unfiltered engine oil contains impurities such as metal shavings, and impurities entering the engine will still cause damage to the engine

In addition, the metal shavings in the oil filter are easy to clog the filter element, which restricts the flow of oil through the filter element, which is not conducive to the oil filter to filter the oil.
