Venturi Air Spring Damping for Asymmetric Compression and Rebound

The patent combines the damping function with the air spring structure itself by creating a second pressure chamber within the bellows and using internal air flow paths with throttles and valves. This merges what were previously separate components (air spring and hydraulic damper) into a single integrated unit, eliminating the need for parallel hydraulic shock absorbers and reducing overall device complexity

The patent implements a nested structure where the second pressure chamber is formed within the bellows of the air spring itself. The damping components (throttles, valves, air channels) are integrated within this nested chamber, allowing the damping system to occupy the same space as the air spring rather than requiring additional external space

The patent replaces the hydraulic fluid-based damping system with a pneumatic system using compressed air. The air spring uses internal air flow through throttles and valves to create damping effects, substituting the mechanical-hydraulic system with a pneumatic system that eliminates environmental contamination risks associated with hydraulic fluid leakage and disposal

The patent implements dynamic damping characteristics by incorporating valves that can change their flow characteristics based on operating conditions. The system includes check valves and controllable valves that adjust air flow resistance dynamically, allowing the damping effect to adapt to different vibration amplitudes and frequencies rather than being fixed like a simple orifice plate

The patent merges the damping function into the air spring structure by creating an integrated design where the second pressure chamber, air channels, throttles, and valves are all part of the same assembly. This eliminates the need for separate damping components and their associated mounting hardware, reducing overall weight while maintaining damping functionality
