The information displayed by the National Intellectual Property Administration shows that Ruili Group Ruian Automotive Parts Co., Ltd. has obtained a patent named "A Clutch Assist Device with a Hydraulic Damper Valve", with the patent number CN223049272U, and the application date is May 2025.
The patent abstract shows that the clutch assist device includes a clutch assist device assembly, which is connected to a hydraulic cylinder that is provided with a hydraulic shock absorber valve fordampening sudden changes or pressure peaks in the hydraulic pressure of the hydraulic cylinder. With this design, the sudden change or pressure peak generated hydraulic oil pressure can be transmitted to the hydraulic shock absorber valve, which uses it to balance the sudden pressure changes in the hydraulic cavity, reducing the pressure directly transmitted to the clutch and ensuring that the hydraulic pressure in the hydraulic cylinder is smoothly output, avoiding the impact of sudden pressure changes or excessive pressure peaks in the hydraulic cavity on the stability of product control hydraulic and output pressure.
According to Tianyancha data, Ruili Group Rui'an Automotive Parts Co., Ltd. was established in 2004, located in Wenzhou City, and mainly engaged in the automotive manufacturing industry. The company has made external investments in 2 enterprises, participated in 83 bidding projects, and has 1065 patent information and 46 administrative permits. The acquisition of this patent is expected to further enhance Ruili Group's technological advantage in the clutch master cylinder field and promote industry technological innovation.
