Oil filter assembly

Abstract

The invention discloses an oil filter assembly, comprising a filter for filtering oil, and an installation seat, wherein the filter is connected with the installation seat through a connection pipe; the upper part in the installation seat is provided with a post-filtered oil outlet; an oil outlet chamber of the filter is connected with a main oil gallery of an engine through the post-filtered oil outlet; the lower part in the installation seat is provided with an oil return device, and an oil return control mechanism; the upper part of the oil return device is a sealing face cavity; the bottom end of the sealing face cavity is fixedly connected with an extension rod with an axial thread; the bottom end of the extension rod is arranged in an installation hole in the installation seat; and additionally, a pre-filtered oil return port of the oil return device used for the return of pre-filtered oil in the removal of the filter, and a general oil return port of the oil return device used for the return of the oil in the sealing face cavity of the oil return device, are arranged on the sealing face cavity of the oil return device. The oil filter assembly is strong in tightness, reliable in action and applicable for various engines.

Description

technical field [0001] The invention belongs to the field of automobiles, and relates to a device for providing clean engine oil for vehicle engines and other components, in particular to an engine oil filter assembly. Background technique [0002] At present, most of the existing oil filters are placed upside down at the bottom of the engine. When they are replaced regularly, workers need to enter the bottom of the car or use complicated tools to replace them, which is inconvenient to operate and poses a safety hazard. [0003] In order to facilitate installation, some engine manufacturers use non-inverted oil filters. Since the oil inlet of the oil filter is downward, when it is disassembled, part of the oil in the oil filter will flow into the oil filter mounting seat. If these oil deposits are not drained in time, the oil may overflow from the edge of the oil filter mount and flow to the components at the lower end of the engine, thereby risking corrosion of components o...

AI Technical Summary

Problems solved by technology

[0005] 1) The seal ring is completely used for sealing, and the seal ring is easy to wear, which will lead to oil leakage, so the risk of failure is greater;

[0006] 2) The oil return device is set in the oil circuit, which is easy to form oil resistance and accelerate the failure of the equipment;

[0007] 3) It is not visible, and it is not easy to be found when it is aging and fails, burying hidden troubles;

[0009] 5) The structure is thin, the strength is insufficient, and the phenomenon of equipment aging often occurs, resulting in serious consequences
