Piston Rings TRIZ Cases
- Gifford-mcmahon (GM) cryocooler first-stage displacer, first-stage displacer assembly, and gifford-mcmahon cryocooler
See how a metal upper cap with precision-machined grooves prevents dimensional drift and abrasi
- Foam Dispenser Pump Passageway Layout to Reduce Dripping
An upward-then-downward passageway in a foam dispenser pump blocks gravity-driven leakage and reduces dripping between uses.
- Piston Ring Groove Asymmetry for Better Air Compressor Intake
An asymmetric piston groove lets the ring shift during retreat, enlarging the wall gap to improve air intake and pressure discharge.
