ABSTRACT:
An apparatus and method for synchronizing the phase of a pair of free piston Stirling machines without changing the design parameters or operating characteristics from the operating mode of each machine alone. Energy is coupled from corresponding gas spaces of each machine into an interconnected sonic transmission line to generate a standing wave in the transmission line. Preferably the transmission line is a tube which is, for example, one wavelength long to cause the two machines to run with their pressure waves in phase.
