Abstract

The invention discloses a bypass valve of an engine oil filter. The bypass valve comprises an end cover, a sealing pad, a gasket, a spring, a valve body with a circular tube structure and a pressure adjusting unit, wherein the end cover is riveted with the valve body, the sealing pad is arranged at the bottom of the valve body, the gasket is arranged at the top of the sealing pad, the spring is arranged at the top of the gasket, the bottom of the pressure adjusting unit is attached to the spring in a pressure mode, moreover, the periphery of the pressure adjusting unit is pressed and fixed tothe inner periphery of the valve body, the diameter of the sealing pad is larger than that of an oil inlet of the end cover, and oil outlet mechanisms are further uniformly arranged on the valve body.Aiming at the technical problems that the pressure of an existing bypass valve is not adjustable, and the pressure tolerance is large after machining, improvement is made; and the bypass valve of theengine oil filter has the advantages that the opening pressure is adjustable, filtering is achieved, the service life is long, and the precision is high.

Description

technical field [0001] The invention relates to the field of engine oil filters for internal combustion engines, in particular to an oil filter bypass valve. Background technique [0002] The bypass valve for the oil filter is an important part of the oil filter. Its function is to let the oil pass through the filter directly when the engine is cold started or the oil filter is blocked but can be replaced in time in the future, so as to prevent the engine from being damaged due to Dry friction occurs without lubrication of lubricating oil. At present, the typical structure of the oil filter bypass valve is a combination of valve body, gasket, support gasket and spring riveted together with the lower end cover. When the oil filter When the oil filter element is blocked, the unfiltered oil will directly enter the valve body from the oil inlet of the lower end cover due to the change of oil pressure, thereby directly supplying oil to the engine. But the biggest disadvantage of...
