High-efficiency oil filter for vehicle with side-opening function

Abstract

This utility model discloses a high-efficiency automotive oil filter with bypass function, including a housing, a cover plate on the top of the housing, an oil inlet and an oil outlet on the cover plate, a cylindrical filter element and a central frame located inside the housing, the upper and lower ends of the filter element and the central frame are fixedly connected by an upper end cover and a lower end cover to form an integral structure, the filter element and the inner wall of the housing form an oil inlet chamber communicating with the oil inlet, at least one magnetic ring is provided in the corresponding area of ​​the oil inlet chamber on the inner wall of the housing, the inner side of the central frame forms an oil outlet chamber communicating with the oil outlet, a bypass valve is provided at the bottom of the oil outlet chamber, and a bypass chamber communicating with the bypass valve is formed between the lower end cover and the housing. This utility model, by setting a bypass valve, allows the oil to flow directly to the oil outlet chamber around the filter element when the oil pressure rises due to filter element blockage, ensuring a continuous oil supply to the engine. The magnetic ring pre-adsorbs metal particles in the oil, reducing the burden on the filter element and improving filtration efficiency.
