TOWARDS FREE PISTON ENGINE APPLICATIONS

Proceedings of the JFPS International Symposium on Fluid Power, 2002
A hydraulic free piston engine (HFPE) combines a diesel engine and a hydraulic pump into one compact component. The piston assembly motion is influenced by pressures and inertia forces only and no mechanical linkage control the motion. The piston assembly moves during operation linearly back and forth between dead centres by means of the fuel energy ...

Interacting Parallel Fluidic Hysterons

Advanced Science, EarlyView.
The parallel coupling of fluidic hysterons is introduced, establishing advanced functionalities in inflatable soft systems. A pressure–volume framework reveals how preset volumes Δv∗${\Delta }v^*$ tune nonlinear interactions between hysterons and actuation sequences without changing architecture. Experiments validate the predictions, opening new routes
