ABSTRACT:
A Stirling cycle engine has power pistons disposed in power cylinders. Each power piston is interconnected by levers fixed on an oscillating shaft to a unidirectionally rotating output crank shaft. Reciprocating displacers are disposed in displacer cylinders separate from the power cylinders, to move the working fluid alternatingly from hot to cold ends of a heat exchanger unit associated with each power piston and cylinder. Variably positionable linkages driven by the power pistons control the length of stroke of reciprocating displacers to control the power output of the engine. Seals associated with rotationally oscillating shafts include spacers to support a flexible sleeve against the force of pressurized gases within the engine casing.
