Definitions
- the invention relates to a cylinder-piston unit, in particular for steam engines with expansion under the supply of heat according to the preamble of the main claim.
- the displacer 3 is guided in its stroke region with play parallel to the surrounding warm cylinder section 41 and has a cross section that becomes smaller in relation to the cylinder head 43.
- the mutually complementary surfaces can be made polygonal.
- the hottest heat transfer path B is assigned to this area.
