oil filter

Abstract

The invention discloses an oil filter. The invention provides an oil filter, wherein a bypass-valve is simple in fixing mode and convenient to disassemble and assemble, and the filter area of a filter element can be increased to guarantee the oil quality. The oil filter solves the technical problems that in the prior art, the bypass-valve is tedious to fix, the oil filter is time and labor-consuming to mount, a filter element assembly needs to be disassembled if being replaced, and the using cost is high. The oil filter comprises a filter housing and a filter element assembly arranged in the filter housing, wherein an oil inlet is formed in the top face of the filter housing corresponding to the outer side of an upper port of the filter element assembly, a bypass-valve is arranged at a lower port of the filter element assembly, and a base bracket covers the lower port of the filter element assembly; the base bracket comprises a bypass-valve locating barrel which extends into a hole in the filter element assembly, the lower port of the bypass-valve locating barrel extends outward along the lower end face of the filter element assembly to form a supporting ring, the edge of the supporting ring further extends downward to form a plurality of supporting legs, the supporting legs elastically prop against the bottom face of the filter housing, and the bypass-valve is fixed on the bottom face of the bypass-valve locating barrel in a penetrating manner.

Description

technical field [0001] The invention relates to a filter, in particular to an oil filter with simple structure, convenient disassembly and assembly of a bypass valve, increased filter area of ​​the filter element, and guaranteed oil quality. Background technique [0002] After the engine has been running for a long time, it will produce a lot of abrasives such as iron filings, and the abrasives will circulate in the oil circuit system with the oil, and the function of the oil is mainly to lubricate, cool and clean the various components. , not only increases the wear and tear of component parts, but even affects the normal operation of the engine in severe cases, so the engine oil must be filtered during use. Existing automotive engines generally use filters to filter the oil in real time to remove dust, carbon deposits, soot particles, and iron filings in the oil to ensure that the crankshaft, connecting rod, camshaft, supercharger, The normal operation of related kinemati...
