Abstract

The invention discloses an oil filter core integrated with a bypass valve and an oil drain valve. The oil filter core comprises a keel, end covers, an oil outlet hole joint, a bypass valve shell, a bypass valve core, and a bypass valve spring; a filter paper is wrapped on the keel, and an oil collecting channel is formed inside the filter paper; two ends of the keel are separately provided with anend cover; the oil outlet hole joint is arranged on one of the end covers, and one end of the oil outlet hole joint communicates with the oil collecting channel, and the other end is used for connecting with a main oil channel of an engine; the bypass valve shell is arranged on the other end cover, one end of the bypass valve shell communicates with the oil collecting channel, and the other end communicates with an internal cavity of the oil filter; and one end of the bypass valve spring is connected with the bypass valve shell, and the other end is connected with the bypass valve core. The oil filter core is simple in structure and can reduce the occupation of space, and can enable the connection between all components to be firm, thereby improving the reliability of protection of the engine.

Description

technical field [0001] The invention relates to the field of engine oil filters, in particular to an engine oil filter core integrated with a bypass valve and an oil discharge valve. Background technique [0002] The oil filter is an important part of the engine. The oil in the engine is sent to the oil filter for filtration, and the filtered oil is then returned to the engine. The oil filter is used to protect the engine by removing impurities such as dust, metal particles, carbon deposits and soot particles from the oil. High-quality oil filters are generally equipped with a bypass valve. When the oil filter becomes clogged, the bypass valve will open under pressure to allow the unfiltered oil to flow directly back to the engine. Even so, the impurities in the oil will enter the engine together, but the damage is much smaller than the damage caused by no oil in the engine. Therefore, the bypass valve is the key to protect the engine in an emergency. [0003] Currently, ...
