AI Technical Summary

Technical Problem

Existing aviation differential pressure signalers use plastic laminates for actuation and triggering, which involves a large number of parts, high friction, and is easily affected by temperature, resulting in poor reliability.

Method used

The design employs a Glyd ring actuation trigger structure to replace plastic stacks, reducing the number of parts. The Glyd ring sealing structure isolates high and low pressure, reduces friction, and improves temperature resistance.

Benefits of technology

This design achieves a simple structure, is less affected by temperature, and improves the reliability and environmental adaptability of the differential pressure signaler.
