ABSTRACT:
An improved transmission from linear power to rotary power in a Stirling heat engine having at least one cylinder with power and displacement pistons linearly operable therein. The power and displacement piston shafts are each interconnected to a common drive shaft through an actuating arm. The power and displacement shaft connections to the actuating arms are through universal joints and their drive shaft connections are rotary connections. The rotary connections of the actuating arms to the drive shaft are eccentrics or cams angularly displaced from the longitudinal center line of the drive shaft and rotatably positioned relative to each other so as to provide the proper operational phase angle of the pistons. A timing shaft running through at least a portion of the drive shaft is translatable a discrete distance to change the relative rotational positions of the eccentrics or cams through 180.degree. of rotation displacement piston eccentric rotates 90.degree. while the power piston eccentric rotates 90.degree. in the opposite direction. Translation of the timing shaft can be accomplished while the engine is in operation to provide engine power and rotational directional control.
