Abstract
In the case of a heat engine, in particular a Stirling engine, comprising a displacement piston and a working piston which are coupled together in a housing sealed in a leak-proof manner against the outside so that they can oscillate in a linear direction, in which case the gas space between the displacement piston and the working piston is connected to the gas space between the displacement piston and the housing by way of a heater, a cooler and a regenerator arrangement to which an external source of heat may be connected, in order to make possible the take-off of mechanical energy from the closed housing for external use, provision is made for one magnetic or magnetizable coupling device (9, 15) located within the housing (1) to be connected at least with the working piston (2) and there is also a corresponding magnetic or magnetizable coupling device (8, 18) outside the housing (1) which is movably mounted in parallel with the piston travel.
