AI Technical Summary
Technical Problem
Existing hydraulic brake valves have difficulty adjusting braking sensitivity for different vehicle weights and driving habits, making hydraulic brakes unsuitable for use in different vehicles.
Method used
A multi-stage flow amplification hydraulic brake valve is designed. By setting large-diameter and small-diameter hydraulic chambers in the valve body and using a rotating shaft to connect multiple valve bodies in series, the movement distance of the output rod is increased, achieving single-pass flow amplification and adjusting braking sensitivity.
Benefits of technology
It improves braking sensitivity, saves space, facilitates adjustment of the number of valve housings connected in series, simplifies the installation process, and enhances braking performance.

Abstract
This invention relates to the field of hydraulic brake valves and discloses a multi-stage flow amplification hydraulic brake valve, including a brake pedal, brake pads, and a hydraulic braking mechanism disposed between the brake pedal and the brake pads. The hydraulic braking mechanism includes multiple support partitions arranged equidistantly from top to bottom. End plates are provided on the two end support partitions that are far apart from each other. Side plates are installed between adjacent support partitions and between the end support partitions and the end plates. Mounting cavities are formed between adjacent support partitions and between the end support partitions and the end plates. A single valve body assembly is installed within the mounting cavity. This invention achieves single-stage flow amplification by having a larger diameter hydraulic cavity within the valve body than a smaller diameter hydraulic cavity. Furthermore, multiple valve bodies are connected in series to achieve multi-stage flow amplification, thereby improving braking sensitivity. The braking sensitivity can be adjusted by the number of valve bodies connected in series.
