POWER PLANT WITH OPPOSED STIRLING ENGINE Russian patent published in 2012 - IPC F02G1/44 F02G1/53 

FIELD: machine building.

SUBSTANCE: power plant with opposed Stirling engine includes heater and cooler. Heater comprises together with a piston a hot cavity. Cooler comprises together with a piston a cold cavity. Hot cavity is connected by means of regenerator to cold cavity. Four tight capsules with hot and cold cavities are introduced to power plant. Pistons of hot and cold cavities of each capsule are connected by means of stocks to toothed racks fixed on them and engaged with rotors of combined electric machines. Hot cavity of the first capsule is connected to cold cavity of the second capsule via the pipeline in series connecting heater, regenerator and cooler. Hot cavity of the second capsule is connected to cold cavity of the third capsule via the pipeline in series connecting heater, regenerator and cooler. Hot cavity of the third capsule is connected to cold cavity of the fourth capsule via the pipeline in series connecting heater, regenerator and cooler. Hot cavity of the fourth capsule is connected to cold cavity of the first capsule via the pipeline in series connecting heater, regenerator and cooler. Inner space of capsules is filled with gas identical to gas in working cavities, the pressure of which is equal to average pressure of working medium in thermodynamic cycle.

EFFECT: invention allows simplifying the design, reducing the losses of working medium, improving reliability and capacity of power plant.
