Abstract
This Stirling machine comprises a transfer piston () and a moving part () of a generator or of an electric motor, the transfer piston () periodically displacing a working gas between an expansion chamber (V) and a compression chamber (V) which chambers are respectively associated with two working faces of the transfer piston () of which the cross-sectional area ratio a/ais >0.35 so that its displacement along an axis X oriented towards the expansion volume (V) generates an in-phase working gas pressure component Pthat opposes the displacement of the piston (), so that all of the mechanical energy produced is transmitted to the moving part (). This machine comprises a resonant second piston () coupled to the transfer piston () by a quantity of energy that is proportional to the pressure component P.
