Abstract
A torsionally flexible seal formed with alternating layers of elastic and reinforcing material provides a gas-tight barrier between a drive shaft and a portion of the Stirling engine housing surrounding a passageway through which the drive shaft extends. The shaft is connected to a series of mechanical linkage devices located within the housing which transmits power between the linearly reciprocative power piston and rotationally reciprocative drive shaft and which eliminates substantially the side forces exerted on the piston.
