Abstract
A hot gas engine operating with a Stirling cycle includes a cylindrical space filled with a process gas and containing one or two working pistons and one or two displacement pistons moveable longitudinally in relation to each other. The displacement piston or pistons are integrated with the respective regenerator. The working and displacement piston or pistons are associated with transmission gears constructed as thrust crank transmissions so as to convert rotary motion into longitudinal piston displacement motion and vice-versa.
