Automobile filter

Abstract

The invention discloses an automobile filter. The automobile filter comprises a shell, a sump oil inlet, a central pipe and a filter element, wherein the filter element is arranged on the outer surface of the central pipe in a sleeving mode; a one-way valve is arranged at the position, positioned between the shell and the filter element, of the bottom of the inner surface of the shell; a blockagefiltering device is further arranged at the bottom end of the shell; the blockage filtering device comprises a bottom shell body; a communicating pipe is fixedly connected to the position, positionedon the central pipe, of the inner surface of the bottom shell body; the inner surface of the communicating pipe communicates with the central pipe; and a plurality of oil passing holes are formed in the outer surface of the communicating pipe. According to the automobile filter, after the filter element arranged on the outer surface of the central pipe in the sleeving mode is blocked, the one-wayvalve can be opened in a jacking mode, sump oil flows into the bottom shell body, is filtered through the filter element in the connecting pipe and then flows to an engine through the central pipe, and therefore the problems existing in the background technology can be effectively solved.

Description

technical field [0001] The invention relates to the field of automobile filter equipment, in particular to an automobile filter. Background technique [0002] Existing oil filters generally filter impurities through the filter element. When the filter paper is used for a period of time, it will gradually be blocked by impurities in the oil and lose the functions of oil filtering and oil supply. In order to ensure smooth oil supply, most oil filters are equipped with The bypass valve structure, when the filter element is blocked, the bypass valve will be opened under the action of oil pressure, so that the unfiltered engine oil can be directly supplied to ensure the normal operation of the engine in emergency situations. [0003] The oil filter mainly includes dirty oil inlet, shell, center pipe, filter paper and bypass valve, that is, when the engine is cold started or the filter element is blocked, the dirty oil will flow from the overflow valve through the center pipe to l...

AI Technical Summary

Problems solved by technology

[0003] The oil filter mainly includes dirty oil inlet, shell, center pipe, filter paper and bypass valve, that is, when the engine is cold started or the filter element is blocked, the dirty oil will flow from the overflow valve through the center pipe to let the unfiltered oil directly supply to ensure that the engine maintains normal operation in emergency situations, that is, there is currently a problem that the bypass oil valve enters the unfiltered engine oil and causes certain damage to the engine
