AI Technical Summary
The addition of control valves to existing air compressor support cylinders has increased the number of leakage points, affecting equipment stability and reliability, and increasing costs.
The air inlet is designed to be inside the mounting hole, and the second and third springs provide a reset force for the second piston, which automatically closes the air inlet, reduces leakage points, improves equipment stability, and reduces costs.
It effectively reduces equipment leakage points, improves operational stability and reliability, and lowers manufacturing costs.
