Example Embodiment

[0022] Example 1:

[0023] Such as figure 1 with figure 2 As shown, the oil filter of the present invention includes a cylindrical shell 19, one end of the cylindrical shell 19 is provided with a lower end cover 5, and the lower end cover 5 is provided with a bypass valve. The bypass valve is sealed in the lower shell 9 Inside the housing 19, an upper end cover 14 is provided at the other end, and a check valve 16 is provided on the upper end cover 14. The check valve 16 is sealed in the housing 19 through the upper housing 15, and the middle of the upper housing 15 is provided with an oil outlet 11, an oil outlet 11 is provided with an oil inlet 18 around the oil inlet 18, the position of the oil inlet 18 corresponds to the position of the check valve 16, a filter element 10 is arranged in the housing 19, and a dragon skeleton 12 is arranged in the hollow position of the filter element 10. One end is sealed and connected with the lower end cover 5, the dragon skeleton 12 is a m...

Example Embodiment

[0032] Example 2:

[0033] Such as image 3 with 4 As shown, this embodiment is the same as the embodiment 1 except that the bypass valve 8 is different from the embodiment 1. The bypass valve 8 is a claw filter bypass valve, and the claw filter bypass valve Including the lower end cover 5, the lower end cover 5 is provided with a cylindrical recess to form a cavity, a through hole is provided in the middle of the cylindrical recess, and the through hole is fitted with a valve body. The valve body includes a valve cover 3 whose diameter is larger than the diameter of the through hole. The claws 21 are symmetrically fixed on the working surface of the valve cover 3. The claws 21 are barbed. A spring 4 is arranged between the barb opening 20 of the claw 21 and the valve cover 3. The spring 4 has a diameter larger than the diameter of the through hole in its natural state. 21 The distance between the outer edge and the center line is greater than the radius of the through hole.

Abstract

The invention relates to an oil filter, and belongs to the field of filters. The oil filter comprises a cylindrical shell body, a lower end cover is arranged at the lower end of the cylindrical shell body, a bypass valve is arranged on the lower end cover, the bypass valve is sealed in the shell body through a lower shell body, an upper end cover is arranged at the other end of the cylindrical shell body, a check valve is arranged on the upper end cover, the check valve is sealed in the shell body through an upper shell body, an engine oil outlet is formed in the middle of the upper shell body, an engine oil inlet is formed around the engine oil outlet, and the position of the engine oil inlet corresponds to the position of the check valve. A filter core is arranged in the shell body, a keel frame is arranged at the hollow position of the filter core, one end of the keel frame is in sealing connection with the upper end cover, the other end of the keel frame is in sealing connection with the lower end cover, the keel frame is a modular keel frame, a concave spigot and a convex spigot which are of the same specification are formed in the head end and the tail end of each module respectively, the adjacent modules are in cooperation through the concave spigots and the convex spigots, filter holes are formed in the keel frame, the shell body and the lower shell body are integrally formed, and are made of transparent plastic materials, and high efficiency and environmental protection are achieved.

Description

technical field [0001] The invention relates to an engine oil filter, which belongs to the field of filters. Background technique [0002] During the working process of the engine, metal wear debris, dust, carbon deposits and colloidal deposits oxidized at high temperatures, water, etc. are continuously mixed into the lubricating oil. The function of the oil filter is to filter out these mechanical impurities and colloids, keep the lubricating oil clean, and prolong its service life. The end caps of the commonly used filters are iron caps, which are easy to scratch. The process requires multiple riveting, spot welding, and gluing, and the exterior needs to be painted, which pollutes the air, is inefficient and labor-intensive, and wastes a lot of time. Contents of the invention [0003] According to the deficiencies in the prior art above, the technical problem to be solved by the present invention is to provide an efficient and environment-friendly engine oil filter. ...
