Patent ID: 8650871

Claim:
A Stirling external combustion engine with a γ configuration comprising a drive shaft, a first actuator cylinder kinematically connected to said drive shaft, a second displacer cylinder kinematically connected to said drive shaft, and a thermodynamic circuit fluidly connected to both said actuator and displacer cylinders, and having at least an expansion chamber and a compression chamber for a heat-carrying fluid, in order to determine the cyclic movement of said first actuator cylinder and said second displacer cylinder, wherein said first actuator cylinder is mounted on a first support frame and said second displacer cylinder is mounted on a second support frame, distinct from and constrained in a mobile manner to the first support frame, wherein said first support frame and said second support frame are reciprocally hinged to each other, in correspondence with an axis of rotation of said drive shaft, movement means being mechanically connected to said first support frame and/or said second support frame, in order to determine the desired relative movement of said first support frame and said second support frame and to vary the reciprocal kinematic connection phasing of said two actuator and displacer cylinders with respect to said drive shaft.
