Abstract
This article introduces the pressure‑difference compensation principle of the auxiliary oil reservoir, the online self‑filtration function of the bypass screen, and the application of the 7075 aluminum alloy CNC‑machined housing.

Core Technical Points
- The auxiliary oil reservoir temporarily stores and returns oil through pressure‑difference compensation, smoothing out pressure pulsations and preventing cavitation.
- The built‑in sintered stainless steel filter screen enables online self‑filtration of the damping oil, capturing metal debris and contaminants.
- The removable filter element design improves after‑sales service convenience and reduces disassembly costs.
- Improper design of the filter screen’s flow resistance may lead to high‑frequency damping fade or response lag.
- The bypass circuit introduces additional sealing interfaces, requiring zero‑leakage performance in press‑fit and welding processes.
- The 7075 aluminum alloy CNC housing combines lightweight construction with corrosion resistance, and supports sensor integration.
Detailed Content
In shock absorbers used in racing cars, off‑road modified vehicles, and certain top‑tier luxury passenger cars, the guide assembly has evolved into a highly integrated, intelligent fluid management module.
