Abstract
The invention discloses an oil filter for avoiding secondary abrasion of engines. The oil filter comprises a shell, a filter element and a filter screen assembly. A chamber separation assembly is arranged in an internal chamber of the shell, and the internal chamber of the shell is divided into a working chamber and a residue storage chamber through the chamber separation assembly. The filter element is arranged in the working chamber, an oil return channel is reserved between the bottom of the filter element and the chamber separation assembly, and a bypass valve is arranged at the bottom of the filter element. An oil outlet and an oil inlet hole are formed in the shell. The filter screen assembly is arranged in the residue storage chamber, and comprises a plurality of filter screen layers which are horizontally arranged. The chamber separation assembly comprises a check ring, a valve plate and a spring assembly. The check ring is fixedly connected to the inner wall of the shell, and a flow pass is formed in the middle of the check ring. The valve plate is used for closing the flow pass, and a one-way overflowing hole is formed in the valve plate. The two ends of the spring assembly are connected with the valve plate and the bottom surface of the residue storage chamber respectively, and the deformation stress of the spring assembly is smaller than the opening pressure of the bypass valve. The oil filter avoids secondary abrasion of engines.
