Abstract

The pressure containment device for containing pressurized gas within a Stirling engine is characterized by enclosing a drive mechanism housing with a cylindrical pressure hull having first and second ends whereby a portion of the drive mechanism housing extends through the first end of the pressure hull and the second end thereof, is rigidly connected to the drive mechanism housing. An o-ring is used to seal the connection where the drive mechanism housing extends through the first end of the pressure hull to allow small axial and radial relative motions therebetween. An output shaft extends along the axis of revolution of the pressure hull and is supported by front and rear main bearings and a thrust bearing, all rigidly connected to the drive mechanism housing. A rotating shaft seal, also connected to the drive mechanism housing, prevents pressurized gas from escaping along the output shaft.
