Abstract:
1. A closed Stirling cycle power system, comprising: a housing having a drive shaft defining a central axis; a hot side including a hot rotor and a hot stator and hot side displacing chambers created in an offset space therebetween, the hot stator and hot side displacing chambers being fixed with respect to the housing and centered around the central axis, while the hot rotor rotates within the hot stator about a hot rotor axis offset with respect to the central axis and is connected to rotate the drive shaft, and wherein the hot rotor axis orbits around the central axis; a cold side including a cold rotor and a cold stator and cold side displacing chambers created in an offset space therebetween, the cold stator and cold side displacing chambers being fixed with respect to the housing and centered around the central axis, while the cold rotor rotates within the cold stator about a cold rotor axis offset with respect to the central axis and is connected to rotate the drive shaft, and wherein the cold rotor axis orbits around the central axis, wherein the rotational angle of the cold rotor is out of phase with the rotational angle of the hot rotor; and a stationary barrier member of thermally insulating material between the hot and cold sides, the barrier member having regenerative gas passages to allow gasses to flow therethrough thus connecting the displacing chambers of the hot and cold sides, wherein when rotary power is applied to the drive shaft the device will act as a heat pump and the hot side will get hotter and the cold side will get colder.
