Compressible component tester e.g. for shock absorber, applies compressed air pressure using pneumatic piston to shock absorber holder

摘要

The shock absorber (12) held between holders (16,18), is applied with compressed air pressure from pneumatic piston (28) of a drive assembly (24), through proportional valve (36) under PID control. A portable computer analyzes absorber property during the stroke cycle and stores the result.
