Description

Technical Field

[0001] The utility model relates to the technical field of valve bodies, in particular to an automobile control valve body structure. Background Art

[0002] In automobile engines, oil circuit control valves are used to adjust the hydraulic oil changes of the oil pump to adjust the output pressure.

[0003] For example, a vehicle control valve body with patent number CN215981129U includes: a valve body, a first bracket, a second bracket, a fixing device and a buffer device; the fixing device is used to fix the valve body, the fixing device and the first bracket are fixedly connected, the buffer device is used to absorb the vibration of the valve body, and the buffer device is arranged between the first bracket and the second bracket; the fixing device includes two groups of sub-fixing devices; a fixing plate is fixedly arranged on the first bracket, and sliding grooves are provided on both sides of the fixing plate. The above documents still have shortcomings. When in use, the elastic deformation of the fifth spring and the sixth spring can also prevent the valve body from shifting, and the fixing device can fix the valve body on the first bracket. On a bracket, when the valve body is displaced due to vibration, the buffer device can absorb the impact force generated by the valve body, thereby ensuring the stability of the valve body and preventing the valve body from circumferential movement, thereby greatly enhancing the stability of the structure. However, a traditional automobile control valve body is usually a single-plate rotary valve. When the hydraulic oil flows in the pipeline, the valve plate rotates and the hydraulic oil passes through the outside of the valve plate, which will make the hydraulic oil unable to flow evenly in the pipeline, thereby affecting the adjustment of the output pressure. At the same time, when the hydraulic cylinder flows in the pipeline, if the hydraulic oil flows back, the output pressure will change. When the hydraulic oil flows in the pipeline, it is not convenient to prevent the hydraulic oil from flowing back. Utility Model Content
