• Specification

• Function 

1. Gas Pressure Support
Function: Supports the weight of the moving part (e.g., engine hood) to make opening and closing easier.
Technical Feature: Sealed cylinder filled with high-pressure inert gas (usually nitrogen) and an oil-gas mixture. The pressure difference between the two sides of the piston generates an upward force.
Importance: Reduces operator effort, prevents sudden drops, and ensures smooth movement.

2. Speed Control & Damping
Function: Controls the opening and closing speed of the component to prevent sudden movements.
Technical Feature: Piston with small orifices restricts the flow of oil or gas, creating resistance proportional to the speed of movement.
Importance: Protects the hinge and connected parts from impact damage, improves safety, and reduces noise.
