A hot gas engine which uses elliptical members in place of gears or connecting rod linkages to couple the reciprocating pistons to the central shaft of the machine, thereby reducing friction and overall size of the machine, reducing weight to power ratios and increasing efficiency. The elliptical members are so designed as to provide two power strokes per revolution of the central shaft, and the piston and cylinder arrangement is such that they spiral around the body of the machine, allowing a very compact engine.
