Description

Technical Field

[0001] The utility model relates to the technical field of fuel cut-off devices, in particular to an aluminum alloy fuel cut-off device with a bent-through structure. Background Art

[0002] Brake fluid is a liquid medium that transmits braking pressure in a hydraulic braking system and is used in vehicles with a hydraulic braking system. Brake fluid, also known as brake oil or pressure fluid, is an indispensable part of the braking system. In the braking system, it serves as a medium for force transmission. Since liquids cannot be compressed, the pressure output from the master cylinder is directly transmitted to the slave cylinder through the brake fluid. When disassembling the brake pipeline, the brake oil will leak out. Therefore, a valve needs to be added to ensure that no oil leakage occurs during disassembly. Content of the Utility Model
