Problems solved by technology

[0002] In fuel engines such as automobiles and motorcycles, more and more EFI technology is used. Since EFI technology uses electronic induction, it uses computers to precisely control the amount of fuel injected to achieve the purpose of saving energy. The control of oil pump oil A pressure regulating valve located in the oil tank is required to control the amount of oil in the pipeline, and the existing control valves have always had noise problems in the industry
[0003] In order to reduce the noise, the industry has adopted the design of reducing the output diameter. However, although the reduction of the output diameter can help to improve the noise, it will undoubtedly increase the pumping pressure of the oil pump, resulting in an increase in the load of the oil pump. , in view of this, the inventor has made an improvement

Embodiment 1

[0024] see figure 1 , figure 2 , Figure 4 , an improved silent control valve for an oil pump according to the present invention, comprising a valve seat 1, the valve seat 1 is provided with a valve cavity 11 and a mixing guide hole 12 communicating with the valve cavity 11, and the surroundings of the mixing guide hole are evenly distributed. An oil distribution hole 13 also includes a valve core 2, a sealing ball 3 and a push seat 4 for pushing the sealing ball 3, the valve cavity 11 is provided with an elastic mechanism 5, and the valve core 2 is provided with a through oil passage 21, so The inner end of the through oil passage 21 is provided with an arc flare 22 matched with the sealing ball 3, and the push seat 4 is provided with a guide column 41, and the guide column 41 extends to the outside of the mixing guide hole 12, and the elastic The mechanism 5 is socketed on the guide column 41 and drives the push seat 4 to move along the valve cavity 11. The push seat 4 pu...

Embodiment 2

[0033] see image 3 , the present embodiment is further improved and optimized on the basis of Embodiment 1, because 50% of the noise of the whole control valve is generated from the elastic mechanism (such as a spring) under the resonance of the repeated movement of the sealing ball 3, so that the push seat 4 and the valve The inner wall of the cavity 11 forms a bumping noise. In view of this, in order to make the push seat can be guided by the guide post 41, the mixing guide hole is provided with a guide protruding ring extending into the valve cavity, and the guide post passes through the guide post 41. Convex ring6.

[0034] As for the height of the guide protrusion ring 6, in the present technical solution, the extension height of the guide protrusion ring 6 is equal to or greater than 1mm, and those skilled in the art can set a higher guide protrusion according to the larger stroke of the push seat 4. Ring, the inner end of the guide protruding ring 6 is provided with a...
