Description

Technical Field

[0001] This utility model relates to the field of oil control valves, and more particularly to an oil control valve for an automobile engine. Background Technology

[0002] During the operation of a car engine, the oil control valve, as a key component of the lubrication system, directly affects the engine's efficiency and lifespan. The oil control valve is responsible for regulating the pressure and flow of oil, ensuring adequate lubrication of all moving parts of the engine, reducing frictional losses, and lowering operating temperatures. With the automotive industry's ever-increasing demands for engine performance, reliability, and durability, optimizing the performance and expanding the functions of the oil control valve has become an important direction for technological research and development.

[0003] Existing automotive engine oil control valves typically employ a mechanical design, controlling oil flow through the reciprocating motion of a valve core within the valve body. The valve core's movement is driven by electromagnetic or hydraulic force, achieving precise control through spring return. The valve body contains a complex flow channel system; oil flows in through the inlet and, regulated by the valve core, is delivered to various lubrication points in the engine via different outlets. This design meets basic oil control requirements, ensuring proper lubrication of the engine under normal operating conditions.

[0004] However, in actual operation, when the engine oil is delivered to the inside of the connecting pipe, it inevitably carries impurities such as metal shavings and gum. Existing oil control valves lack effective filtration measures. These impurities, along with the flow of engine oil, will cause wear on the inner wall of the connecting pipe and other precision components, leading to increased component gaps and reduced sealing performance. This, in turn, affects the adjustment accuracy and service life of the oil control valve, increasing the risk of engine failure. Therefore, a new type of automotive engine oil control valve is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an automotive engine oil control valve, which aims to improve the problem of impurities in the oil causing wear on the inner wall of the product after the oil is delivered to the connecting pipe.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-4The present invention provides an embodiment of an automobile engine oil control valve, including an oil control valve 1, a filter assembly provided at the input end of the oil control valve 1, and a sealing assembly provided on the outer wall of the oil control valve 1. The filter assembly is used to separate impurities from the oil entering the oil control valve 1 to prevent impurities from causing wear to internal parts, and the sealing assembly is used to enhance the sealing between the oil control valve 1 and adjacent components to prevent oil leakage.

[0033] The filter assembly includes a filter screen 12, located at the input end of the oil control valve 1. The filter screen 12 intercepts impurities in the oil, ensuring the cleanliness of the oil entering the oil control valve 1. A connecting pipe 9 is fixedly connected to the outer wall of the filter screen 12, serving to fix the filter screen 12 and guide oil flow. A retaining ring 11 is fixedly connected to one end of the connecting pipe 9, limiting its movement and preventing it from detaching from the fixing pipe 3. A fixing pipe 3 is slidably connected to the outer wall of the connecting pipe 9, supporting it and fixing the position of the filter assembly. One end of the fixing pipe 3 is fixedly connected to the oil control valve 1, with the retaining ring 11 fitting against one end of the fixing pipe 3. A fixing assembly is provided on the outer wall of the filter screen 12, including multiple retaining balls 4 located on the outer wall of the filter screen 12. The retaining balls 4 engage with the inside of the connecting pipe 9, and the retaining balls 4 are used for… To cooperate with the sliding groove 10 to lock and release the connecting tube 9, the fixed tube 3 has multiple sliding grooves 10 inside. The sliding grooves 10 are used to guide the ball 4 to slide and provide movement space. Each ball 4 is slidably connected to the inner wall of the sliding groove 10. The outer wall of the fixed tube 3 is provided with a spring 8. The spring 8 is used to provide elastic force to reset the retaining ring 5 and press the ball 4. One end of the spring 8 is fixedly connected to the retaining ring 5. The retaining ring 5 is used to push the ball 4 into the interior of the connecting tube 9 to achieve fixation. The other end of the spring 8 is fixedly connected to the fixing ring 6. The retaining ring 5 is slidably connected to the outer wall of the fixed tube 3. The outer wall of the retaining ring 5 is fixedly connected to the protective tube 7. The protective tube 7 is used to protect the spring 8 and transmit the thrust. The inner wall of the fixing ring 6 is fixedly connected to the outer wall of the fixed tube 3. The fixing ring 6 is used to fix the other end of the spring 8 and limit the movement range of the protective tube 7. The outer wall of the fixing ring 6 is in contact with the inner wall of the protective tube 7.

[0034] Reference Figure 1 and Figure 5 The sealing assembly includes multiple sealing rings 13, which are used to fit tightly with adjacent components to prevent oil leakage. The multiple sealing rings 13 are located on the outer wall of the oil control valve 1. Multiple fixing rings 2 are fixedly connected to the outer wall of the oil control valve 1. The fixing rings 2 are used to fix the position of the sealing rings 13 and enhance the sealing stability. The inner wall of each fixing ring 2 is fixedly connected to the outer wall of the sealing ring 13. An inflation ring 14 is fixedly connected to the inner wall of each sealing ring 13. The inflation ring 14 is used to make the outer wall of the sealing ring 13 fit tightly with the adjacent components through expansion force, thereby improving the sealing effect.

[0035] Working principle: During the filtration of the oil supplied to the oil control valve 1, impurities in the oil are separated and filtered through the pores on the surface of the filter screen 12. When the impurities on the surface of the filter screen 12 reach a certain level, they push the protective tube 7 to move, causing the inner wall of the spring 8 to separate from the outer wall of the retaining ball 4, and squeezing the spring 8. This provides space for the retaining ball 4 to slide on the inner wall of the slide groove 10. Because the inner wall of the slide groove 10 has a structure that is larger in the middle and smaller at both ends, it provides space for the retaining ball 4 while preventing the retaining ball 4 from separating from the inner wall of the slide groove 10. Next, pull the connecting pipe 9 to separate it from the inner wall of the fixed pipe 3 to facilitate cleaning of impurities on the surface of the filter screen 12. Then, push the connecting pipe 9 back to its original position and release the pushing force on the protective pipe 7. Use the rebound force of the spring 8 to push the retaining ring 5 back to the outer wall of the retaining ball 4, so that the retaining ball 4 engages with the inside of the connecting pipe 9, thereby fixing the filter screen 12 and achieving the filtering effect of the engine oil. This solves the problem of impurities in the engine oil causing wear to the inner wall of the product after the engine oil is delivered to the inside of the connecting pipe 9, and enhances the protective effect of the product.

[0036] During the sealing process of the outer wall of the product, the expansion force of the air ring 14 causes the outer wall of the sealing ring 13 to expand, making the outer wall of the sealing ring 13 fit tightly with the adjacent parts, thus achieving a sealing effect on the product surface. This solves the problem of oil leakage caused by wear of the sealing ring 13 and gaps between adjacent parts after a long period of time, and enhances the sealing performance of the product surface.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
