Abstract
Mechanical arrangements with primary application to single-acting, multiple-piston, Stirling-cycle machines providing a dramatic reduction in mechanical complexity and production cost. Two specific new machines are disclosed in detail, a single-acting, two-piston 'ducted axle' machine and a quasi double-acting, four piston 'drum cam' machine. A power level control subsystem inherent in the ducted axle machine permits engine output to vary from maximum positive through zero to maximum negative under full load conditions by means of the simple rotation of a single moving part.
